| <h1><a name="ApacheFelixMavenBundlePlugin(BND)-BundlePluginforMaven"></a>Bundle Plugin for Maven</h1> |
| |
| <p>This plugin for Maven 2 is based on the <span class="nobr"><a href="http://www.aqute.biz/Code/Bnd" title="Visit page outside Confluence" rel="nofollow">BND<sup><img class="rendericon" src="apache-felix-maven-bundle-plugin-bnd_files/linkext7.gif" alt="" width="7" align="absmiddle" border="0" height="7"></sup></a></span> |
| tool from Peter Kriens. The way BND works is by treating your project |
| as a big collection of classes (e.g., project code, dependencies, and |
| the class path). The way you create a bundle with BND is to tell it the |
| content of the bundle's JAR file as a subset of the available classes. |
| This plugin wraps BND to make it work specifically with the Maven 2 |
| project structure and to provide it with reasonable default behavior |
| for Maven 2 projects.</p> |
| |
| <p><em>NOTE: only compile, runtime and system scoped dependencies are passed to BND. Provided and test dependencies are <b>not</b> included in the classpath seen by BND.</em></p> |
| |
| <p>Since the 1.4.0 release, this plugin also aims to automate OBR (OSGi |
| Bundle Repository) management. It helps manage a local OBR for your |
| local Maven repository, and also supports remote OBRs for bundle |
| distribution. The plug-in automatically computes bundle capabilities |
| and requirements, using a combination of Bindex and Maven metadata.</p> |
| |
| <p><a name="ApacheFelixMavenBundlePlugin(BND)-simpleexample"></a></p> |
| |
| <h1><a name="ApacheFelixMavenBundlePlugin(BND)-SimpleExample"></a>Simple Example</h1> |
| |
| <p>Rather than going straight to a detailed list of plugin features, we |
| will first look at a simple example of how to use the plugin to give an |
| immediate flavor. A detailed "<a href="#ApacheFelixMavenBundlePlugin%2528BND%2529-howto" title="how-to on Apache Felix Maven Bundle Plugin (BND)">how to</a>" will follow.</p> |
| |
| <p>Assume that we have a simple bundle project that has a pubic API package an several implementation packages, such as:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>org.foo.myproject.api |
| org.foo.myproject.impl1 |
| org.foo.myproject.impl2 |
| ... |
| </pre> |
| </div></div> |
| |
| <p>If we also assume that we have a bundle activator in one of the implementation packages, then the <tt><plugins></tt> section of the POM file for this bundle project would look like this:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>... |
| <plugins> |
| <plugin> |
| <groupId>org.apache.felix</groupId> |
| <artifactId>maven-bundle-plugin</artifactId> |
| <extensions>true</extensions> |
| <configuration> |
| <instructions> |
| <Export-Package>org.foo.myproject.api</Export-Package> |
| <Private-Package>org.foo.myproject.*</Private-Package> |
| <Bundle-Activator>org.foo.myproject.impl1.Activator</Bundle-Activator> |
| </instructions> |
| </configuration> |
| </plugin> |
| </plugins> |
| ... |
| </pre> |
| </div></div> |
| |
| <p>The <tt><Export-Package></tt> and <tt><Private-Package></tt> instructions tell the plugin about the contents of the resulting bundle JAR file. The <tt><Export-Package></tt> instruction tells the plugin which of the available packages to copy into the bundle <b>and</b> export, while the <tt><Private-Package></tt> instruction indicates which of the available packages to copy into the bundle <b>but not</b> |
| export. If the two sets overlap, as they do in the case, then the |
| export takes precedence. Since we did not specify any values for any |
| other bundle manifest headers, they will assume default values which |
| are described <a href="#ApacheFelixMavenBundlePlugin%2528BND%2529-defaultbehavior" title="default-behavior on Apache Felix Maven Bundle Plugin (BND)">below</a>. One specific behavior to highlight is that the plugin generates the <tt>Import-Package</tt> |
| bundle manifest header based on the contents of the bundle, which means |
| that you generally do not ever need to explicitly specify it yourself. |
| That's it.</p> |
| |
| <h1><a name="ApacheFelixMavenBundlePlugin(BND)-Features"></a>Features</h1> |
| |
| <p>The BND library underlying the plugin defines instructions to direct |
| its behavior. For this Maven plugin, these instructions are issued in |
| the plugin configuration section of the POM file, as was illustrated <a href="#ApacheFelixMavenBundlePlugin%2528BND%2529-simpleexample" title="simple-example on Apache Felix Maven Bundle Plugin (BND)">above</a>. BND recognizes three types of instructions:</p> |
| |
| <ol> |
| <li><em>Manifest headers</em> - Any instruction that starts with |
| a capital letter will appear in the resulting bundle's manifest file; |
| the value for the header will either be copied, augmented, or generated |
| by BND depending on the instruction.</li> |
| <li><em>Variables</em> - Any instruction starting with a lowercase letter is assumed to be a variable in the form of a name-value pair, such as <tt>version=3.0</tt>, that can be used for property substitution, but is not copied to the manifest.</li> |
| <li><em>Directives</em> |
| - Any instruction starting with a '-' character is considered to be a |
| directive that informs BND to perform some special processing and is |
| not copied to the manifest.</li> |
| </ol> |
| |
| |
| <p>The remainder of this section covers the most important aspects of BND's instructions; for complete details refer to the <span class="nobr"><a href="http://www.aqute.biz/Code/Bnd" title="Visit page outside Confluence" rel="nofollow">BND documentation<sup><img class="rendericon" src="apache-felix-maven-bundle-plugin-bnd_files/linkext7.gif" alt="" width="7" align="absmiddle" border="0" height="7"></sup></a></span>.</p> |

| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Instructions"></a>Instructions</h2> |
| |
| <h3><a name="ApacheFelixMavenBundlePlugin(BND)-{{<ExportPackage>}}"></a><tt><Export-Package></tt></h3> |
| |
| <p>The <tt><Export-Package></tt> instruction is a list of |
| packages for the bundle to export. These packages are copied into the |
| resulting bundle JAR file from the available classes (i.e., project |
| classes, dependencies, and class path); thus, it is possible to include |
| classes into your bundle that are not associated with source files in |
| your project. <tt><Export-Package></tt> can be specified with |
| package patterns using the '*' wildcard. Also, it is possible to |
| exclude packages using negation by starting the package pattern with |
| '!'. Thus, non-negated patterns indicate which of the available |
| packages to include in the bundle, whereas negated patterns indicate |
| which should not be included in the bundle.</p> |
| |
| <p>The list of package patterns is ordered and earlier patterns are applied before later patterns. For example, if you specify "<tt>org.foo.*,!org.foo.impl</tt>" the second pattern has no effect since all <tt>org.foo</tt> packages have already been selected by the first pattern. Instead, you should specify "<tt>!org.foo.impl,org.foo.*</tt>", which will export all <tt>org.foo</tt> packages except <tt>org.foo.impl</tt>.</p> |
| |
| <p>Following standard OSGi R4 syntax, package patterns can include both |
| directives and attributes, which will be copied appropriately into the |
| generated Export-Package manifest header. Besides explicitly listing |
| package version attributes, BND will also determine package versions by |
| examining the source JAR file or from <tt>packageinfo</tt> files in the package directory.</p> |
| |
| <h3><a name="ApacheFelixMavenBundlePlugin(BND)-{{<PrivatePackage>}}"></a><tt><Private-Package></tt></h3> |
| |
| <p>The <tt><Private-Package></tt> instruction is similar in every way to the <tt><Export-Package></tt> instruction, except for the fact that these packages will <b>not</b> |
| be exported by the bundle. If a package is selected by both the export |
| and private package headers, then the export takes precedence.</p> |
| |
| <h3><a name="ApacheFelixMavenBundlePlugin(BND)-{{<IncludeResource>}}"></a><tt><Include-Resource></tt></h3> |
| |
| <p>The <tt><Include-Resource></tt> instruction is a list of |
| arbitrary resources that should be copied into the bundle JAR file. The |
| specified resources are declared as clauses that can have the following |
| forms:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>clause ::= assignment | inline | simple |
| assignment ::= PATH '=' PATH |
| simple ::= PATH |
| inline ::= '@' PATH |
| </pre> |
| </div></div> |
| |
| <p>For the <tt><Include-Resource></tt> instruction, actual file paths are relative to the <tt>pom.xml</tt>, while file copy destinations are relative to the root of the resulting bundle JAR file. In the case of <tt>assignment</tt> or <tt>simple</tt> forms, the <tt>PATH</tt> parameter can point to a file or directory. The <tt>simple</tt> |
| form will place the resource in the bundle JAR with only the file name, |
| i.e., without any path component. For example, including <tt>src/main/resources/a/b.c</tt> will result in a resource <tt>b.c</tt> in the root of the bundle JAR. If the <tt>PATH</tt> |
| points to a directory, the entire directory hierarchy is copied into |
| the resulting bundle JAR file relative to the specified directory. If a |
| specific resource must be placed into a subdirectory of the bundle jar, |
| then use the <tt>assignment</tt> form, where the first path is the the |
| destination path (including file name if the resource is a file) and |
| the second path is the resource to copy. The <tt>inline</tt> form requires a ZIP or JAR file, which will be completely expanded in the bundle JAR.</p> |
| |
| <p>If a resource clause is specified inside of "{ ... }" brackets, then |
| variable substitution will be performed on the resource, where |
| variables in the resources are denoted with "${ ... }" syntax.</p> |
| |
| <p>By default the bundle plugin converts the project's Maven resource directories into a single <tt><Include-Resource></tt> instruction. If you specify your own <tt><Include-Resource></tt> instruction, this will replace the generated one. To include the generated list of Maven resources in your own <tt><Include-Resource></tt> instruction just add {<tt>maven-resources</tt>} to the list and it will be expanded automatically.</p> |
| |
| <h3><a name="ApacheFelixMavenBundlePlugin(BND)-{{<ImportPackage>}}"></a><tt><Import-Package></tt></h3> |
| |
| <p>The <tt><Import-Package></tt> instruction is a list of |
| packages that are required by the bundle's contained packages. The |
| default for this header is "*", resulting in importing all referred |
| packages. This header rarely has to be explicitly specified. However, |
| in certain cases when there is an unwanted import, such an import can |
| be removed by using a negation package pattern. The package patterns |
| work in the same way as for <tt><Export-Package></tt>, which means they are ordered. For example, if you wanted to import all packages except <tt>org.foo.impl</tt> you would specify "<tt>!org.foo.impl,*</tt>"</p> |
| |
| <p><a name="ApacheFelixMavenBundlePlugin(BND)-defaultbehavior"></a></p> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-DefaultBehavior"></a>Default Behavior</h2> |
| |
| <p>To use this plugin, very little information is required by BND. As |
| part of the Maven integration, the plugin tries to set reasonable |
| defaults for various instructions. For example:</p> |
| |
| <ul> |
| <li><tt><Bundle-SymbolicName></tt> is computed using the shared <span class="nobr"><a href="http://svn.apache.org/repos/asf/maven/shared/trunk/maven-osgi/src/main/java/org/apache/maven/shared/osgi/DefaultMaven2OsgiConverter.java" title="Visit page outside Confluence" rel="nofollow">Maven2OsgiConverter<sup><img class="rendericon" src="apache-felix-maven-bundle-plugin-bnd_files/linkext7.gif" alt="" width="7" align="absmiddle" border="0" height="7"></sup></a></span> component, which uses the following algorithm:<br> |
| Get the symbolic name as groupId + "." + artifactId, with the following exceptions: |
| <ul> |
| <li>if |
| artifact.getFile is not null and the jar contains a OSGi Manifest with |
| Bundle-SymbolicName property then that value is returned</li> |
| <li>if |
| groupId has only one section (no dots) and artifact.getFile is not null |
| then the first package name with classes is returned. eg. |
| commons-logging:commons-logging -> org.apache.commons.logging</li> |
| <li>if artifactId is equal to last section of groupId then groupId is returned. eg. org.apache.maven:maven -> org.apache.maven</li> |
| <li>if |
| artifactId starts with last section of groupId that portion is removed. |
| eg. org.apache.maven:maven-core -> org.apache.maven.core</li> |
| </ul> |
| </li> |
| <li><tt><Export-Package></tt> is assumed to be "<tt><Bundle-SymbolicName>.*</tt>", unless <tt><Private-Package></tt> is specified, then <tt><Export-Package></tt> is assumed to be empty.</li> |
| <li><tt><Private-Package></tt> is assumed to be empty by default.</li> |
| <li><tt><Import-Package></tt> is assumed to be "<tt>*</tt>", which imports everything referred to by the bundle content, but not contained in the bundle.</li> |
| <li><tt><Include-Resource></tt> is generated from the project's Maven resources, typically "<tt>src/main/resources/</tt>", |
| which will copy the specified project directory hierarchy into the |
| resulting bundle JAR file, mirroring standard Maven behavior.</li> |
| <li><tt><Bundle-Version></tt> is assumed to be "<tt>${pom.version</tt>}" with '-' character separator of the qualifier replaced with a '.' character.</li> |
| <li><tt><Bundle-Name></tt> is assumed to be "<tt>${pom.name</tt>}".</li> |
| <li><tt><Bundle-Description></tt> is assumed to be "<tt>${pom.description</tt>}".</li> |
| <li><tt><Bundle-License></tt> is assumed to be "<tt>${pom.licenses</tt>}".</li> |
| <li><tt><Bundle-Vendor></tt> is assumed to be "<tt>${pom.organization.name</tt>}".</li> |
| <li><tt><Bundle-DocURL></tt> is assumed to be "<tt>${pom.organization.url</tt>}".</li> |
| </ul> |
| |
| |
| <p>Since the plugin creates bundles for OSGi R4, it hard-codes <tt>Bundle-ManifestVersion</tt> |
| to be '2'. Additionally, it generates imports for every export to |
| ensure package substitutability, which is very important when working |
| with collaborating services. It is possible to override any of these |
| values (except <tt>Bundle-ManifestVersion</tt>) just by specifying the desired value in the plugin configuration section of the POM file.</p> |

| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-GetMaven2"></a>Get Maven2</h2> |
| |
| <p>The first step in the process of using the plugin is downloading and |
| installing the latest version of the Maven2 runtime. The latest Maven2 |
| release and instuctions for getting started with Maven2 can be found at |
| the <span class="nobr"><a href="http://maven.apache.org/index.html" title="Visit page outside Confluence" rel="nofollow">Maven website<sup><img class="rendericon" src="apache-felix-maven-bundle-plugin-bnd_files/linkext7.gif" alt="" width="7" align="absmiddle" border="0" height="7"></sup></a></span>.</p> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-UsingthePlugin"></a>Using the Plugin</h2> |
| |
| <p>To use the maven-bundle-plugin, you first need to add the plugin and |
| some appropriate plugin configuration to your bundle project's POM. |
| Below is an example of a simple OSGi bundle POM for Maven2:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre><project> |
| <modelVersion>4.0.0</modelVersion> |
| <groupId>my-osgi-bundles</groupId> |
| <artifactId>examplebundle</artifactId> |
| <packaging>bundle</packaging> <!-- (1) --> |
| <version>1.0</version> |
| <name>Example Bundle</name> |
| <dependencies> |
| <dependency> |
| <groupId>org.apache.felix</groupId> |
| <artifactId>org.osgi.core</artifactId> |

| </dependency> |
| </dependencies> |
| <build> |
| <plugins> |
| <plugin> <!-- (2) START --> |

| </instructions> |
| </configuration> |
| </plugin> <!-- (2) END --> |
| </plugins> |
| </build> |
| </project> |
| </pre> |
| </div></div> |
| |
| <p>There are two main things to note: (1) the <tt><packaging></tt> |
| specifier must be "bundle" and (2) the plugin and configuration must be |
| specified (the configuration section is where you will issue |
| instructions to the plugin).</p> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-RealWorldExample"></a>Real-World Example</h2> |
| |
| <p>Consider this more real-world example using Felix' Log Service |
| implementation. The Log Service project is comprised of a single |
| package: <tt>org.apache.felix.log.impl</tt>. It has a dependency on |
| the core OSGi interfaces as well as a dependency on the compendium OSGi |
| interfaces for the specific log service interfaces. The following is |
| its POM file:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre><project> |
| <modelVersion>4.0.0</modelVersion> |

| </plugins> |
| </build> |
| </project> |
| </pre> |
| </div></div> |
| |
| <p>Notice that the <tt><Export-Package></tt> instruction |
| specifies that the bundle exports the Log Service package, even though |
| this package is not contained in the bundle project. By declaring this, |
| the plugin will copy the Log Service package into the resulting bundle |
| JAR file. This is useful in this case because now the bundle can |
| resolve without having to download the entire compendium bundle. The |
| resulting manifest for the Log Service bundle looks like this (notice |
| how the imports/exports automatically have version information |
| associated with them, which was obtained from packageinfo files in the |
| source packages):</p> |

| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-BuildingthePlugin"></a>Building the Plugin</h2> |
| |
| <p>The plugin is hosted at the Apache Felix project. The following |
| steps describe how to build and install the plugin into your local |
| Maven2 repository.</p> |
| |
| <p>Using the SVN client of your choice, checkout the maven-bundle-plugin project.</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>$ svn co http://svn.apache.org/repos/asf/felix/trunk/bundleplugin |
| </pre> |
| </div></div> |
| |
| <p>Using Maven2, build and install the maven-bundle-plugin by issuing |
| the following Maven2 command in the project directory that was created |
| as a result of the previous step.</p> |

| <p>There are also new instructions available from the underlying BND |

| |
| <p>The default goal <b><tt>bundle</tt></b> will be initialized by setting the <packaging> entry to "bundle".</p> |
| |
| <h1><a name="ApacheFelixMavenBundlePlugin(BND)-Thefollowingfeaturesareonlyavailablefromversion1.2.0onwards"></a>The following features are only available from version 1.2.0 onwards</h1> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Embeddingdependencies"></a>Embedding dependencies</h2> |
| |
| <p>The Maven Bundle Plugin supports embedding of selected project dependencies inside the bundle by using the <tt><Embed-Dependency></tt> instruction:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><Embed-Dependency></span>dependencies<span class="code-tag"></Embed-Dependency></span></pre> |
| </div></div> |
| |
| <p>where:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>dependencies ::= clause ( ',' clause ) * |
| clause ::= MATCH ( ';' attr '=' MATCH | ';inline=' inline ) |
| attr ::= 'groupId' | 'artifactId' | 'version' | 'scope' | 'type' | 'classifier' |
| inline ::= 'true' | 'false' | PATH ( '|' PATH ) * |
| MATCH ::= <globbed regular expression> |
| PATH ::= <Ant-style path expression> |
| </pre> |
| </div></div> |
| |
| <p>The plugin uses the <tt><Embed-Dependency></tt> instruction to transform the project dependencies into <tt><Include-Resource></tt> and <tt><Bundle-ClassPath></tt> |
| clauses, which are then appended to the current set of instructions and |
| passed onto BND. If you want the embedded dependencies to be at the |
| start or middle of <tt><Include-Resource></tt> or <tt><Bundle-ClassPath></tt> then you can use {<tt>maven-dependencies</tt>}, which will automatically expand to the relevant clauses.</p> |
| |
| <p>The MATCH section accepts alternatives, separated by <b>|</b>, and can be negated by using <b>!</b> at the <em>beginning</em> of the MATCH. Use <b>*</b> to represent zero or more unknown characters and <b>?</b> to represent a single unknown character. There is no need to escape the <b>.</b> character inside MATCH. The first MATCH in a clause will filter against the artifactId.</p> |
| |
| <p>some examples:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><span class="code-comment"><!-- embed all compile and runtime scope dependencies --></span></span> |

| <span class="code-tag"><Embed-Dependency></span>junit;scope=runtime<span class="code-tag"></Embed-Dependency></span> |
| |

| <span class="code-tag"><Embed-Dependency></span>*;scope=!runtime;type=!pom;inline=true<span class="code-tag"></Embed-Dependency></span> |
| |
| <span class="code-tag"><span class="code-comment"><!-- embed all compile and runtime scope dependencies, except those with artifactIds in the given list --></span></span> |
| <span class="code-tag"><Embed-Dependency></span>*;scope=compile|runtime;inline=false;artifactId=!cli|lang|runtime|tidy|jsch<span class="code-tag"></Embed-Dependency></span> |
| |
| <span class="code-tag"><span class="code-comment"><!-- inline contents of selected folders from all dependencies --></span></span> |
| <span class="code-tag"><Embed-Dependency></span>*;inline=images/**|icons/**<span class="code-tag"></Embed-Dependency></span></pre> |
| </div></div> |
| |
| <p>examples of using {<tt>maven-dependencies</tt>}:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><Include-Resource></span> |
| {maven-resources}, {maven-dependencies}, |
| org/foo/Example.class=target/classes/org/foo/Example.class |
| <span class="code-tag"></Include-Resource></span> |
| |
| <span class="code-tag"><Bundle-ClassPath></span>.,{maven-dependencies},some.jar<span class="code-tag"></Bundle-ClassPath></span></pre> |
| </div></div> |
| |
| <p>By default matched dependencies are embedded in the bundle as <tt>artifactId-version.jar</tt>. This behaviour can be modified using the following instructions:</p> |
| |
| <ul> |
| <li><tt><Embed-StripVersion>true</Embed-StripVersion></tt> - removes the version from the file (ie. <em>artifactId.jar</em>)</li> |
| <li><tt><Embed-StripGroup>false</Embed-StripGroup></tt> - adds the groupId as a subdirectory (ie. <em>groupId/artifactId-version.jar</em>)</li> |
| <li><tt><Embed-Directory>directory</Embed-Directory></tt> - adds a subdirectory (ie. <em>directory/artifactId-version.jar</em>)</li> |
| </ul> |
| |
| |
| <p>Normally the plugin only checks direct dependencies, but this can be |
| changed to include the complete set of transitive dependencies with the |
| following option:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><Embed-Transitive></span>true<span class="code-tag"></Embed-Transitive></span></pre> |
| </div></div> |
| |
| <p>If you want a dependency inlined instead of embedded add the <tt>inline=true</tt>. For example to inline all <em>compile</em> and <em>runtime</em> scoped dependencies use:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><Embed-Dependency></span>*;scope=compile|runtime;inline=true<span class="code-tag"></Embed-Dependency></span></pre> |
| </div></div> |
| |
| <h3><a name="ApacheFelixMavenBundlePlugin(BND)-EmbedDependencyandExportPackage"></a>Embed-Dependency and Export-Package</h3> |
| |
| <p>If you embed a dependency with <tt><Embed-Dependency></tt>, and your <tt><Export-Package></tt> or <tt><Private-Package></tt> instructions match packages inside the embedded jar, you will see some duplication inside the bundle. This is because the <tt><Export-Package></tt> and <tt><Private-Package></tt> |
| instructions will result in classes being inlined in the bundle, even |
| though they also exist inside the embedded jar. If you want to export |
| packages from an embedded dependency without such duplication then you |
| can either inline the dependency, or use a new BND instruction called <tt><_exportcontents></tt>.</p> |
| |
| <p><tt><_exportcontents></tt> behaves just like Export-Package, except it doesn't change the content of the bundle, just what content should be exported.</p> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-OBRintegration"></a>OBR integration</h2> |
| |
| <p>The latest Maven Bundle Plugin automatically updates the local OBR |
| repository.xml file during the install phase, using a default location |
| of:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-java"><LOCAL-MAVEN-REPOSITORY>/repository.xml</pre> |
| </div></div> |
| |
| <p>You can configure the location of the OBR repository by using the command line:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-java">mvn clean install -DobrRepository=<PATH_TO_OBR></pre> |
| </div></div> |
| |
| <p>or in the configuration section for the maven-bundle-plugin in your Maven POM:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><groupId></span>org.apache.felix<span class="code-tag"></groupId></span> |

| <span class="code-tag"></instructions></span> |
| <span class="code-tag"></configuration></span></pre> |
| </div></div> |
| |
| <p>to disable OBR installation set the obrRepository to NONE, for example:</p> |

| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Eclipse/PDEintegration"></a>Eclipse/PDE integration</h2> |
| |
| <p>It is possible to configure the Maven Bundle Plugin to put the |
| bundle manifest where Eclipse/PDE expects it, and use the Maven |
| Dependency Plugin to arrange for any embedded dependencies to appear in |
| a local directory that matches the Bundle-ClassPath entries. Here is an |
| example POM that does this:</p> |
| |
| <div class="preformatted"><div class="preformattedContent"> |

| <p>FYI: the above POM was generated using the <tt>pax-create-bundle</tt> command from <span class="nobr"><a href="http://www.ops4j.org/projects/pax/construct/index.html" title="Visit page outside Confluence" rel="nofollow">Pax-Construct<sup><img class="rendericon" src="apache-felix-maven-bundle-plugin-bnd_files/linkext7.gif" alt="" width="7" align="absmiddle" border="0" height="7"></sup></a></span> and then tweaked to demonstrate using the Maven Dependency Plugin to handle embedded jars in Eclipse.</p> |
| |
| <p>With the original Pax-Construct generated POM you would simply use:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-java">mvn clean <span class="code-keyword">package</span> pax:eclipse</pre> |
| </div></div> |

| <p>to create the appropriate Eclipse files and manifest, and also |
| handle any embedded entries. The pax:eclipse goal extends |
| eclipse:eclipse, and supports the same parameters.</p> |

| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Unpackingbundlecontentsto'target/classes'"></a>Unpacking bundle contents to 'target/classes'</h2> |
| |
| <p>Once in a while you may create a bundle which contains additional classes to the ones compiled from <tt>src/main/java</tt>, |
| for example when you embed the classes from another jar. This can |
| sometimes cause unforeseen problems in Maven, as it will use the output |
| directory (<tt>target/classes</tt>) rather than the final bundle, when compiling against projects in the same reactor (ie. the same build).</p> |
| |
| <p>The easiest way to get around this Maven 'feature' is to unpack the |
| contents of the bundle to the output directory after the packaging |
| step, so the additional classes will be found where Maven expects them. |
| Thankfully there is now an easy option to do this in the bundle-plugin:</p> |
| |

| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-UsinganexistingMANIFEST.MFfile"></a>Using an existing MANIFEST.MF file</h2> |
| |
| <p>If you have an existing manifest, you can add this to the Bnd instructions, like so:</p> |
| |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><_include></span>src/main/resources/META-INF/MANIFEST.MF<span class="code-tag"></_include></span> |
| <span class="code-tag"><Export-Package></span>org.example.*<span class="code-tag"></Export-Package></span></pre> |
| </div></div> |
| |
| <p>Bnd will use it when calculating the bundle contents, and will also |
| copy across all manifest attributes starting with a capital letter.<br> |
| As shown in the above example, you could use this to include a non-OSGi |
| manifest which you then customize with extra OSGi attributes.</p> |
| |

| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-bundle:ant"></a>bundle:ant</h2> |
| |
| <p>The <b>ant</b> goal creates a customized <tt>build.xml</tt> Ant script along with a collection of BND instructions and properties, taken from the current project and stored in <tt>maven-build.bnd</tt>. You also need to run <b><tt>ant:ant</tt></b> to create the standard Ant support tasks to download Maven dependencies and perform compilation, etc.</p> |
| |
| <p>The customized Ant script uses the BND tool to rebuild the bundle, |
| so any source changes should be reflected in the (re)generated manifest.</p> |
| |
| <p>Example:</p> |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>mvn ant:ant bundle:ant |

| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-bundle:clean"></a>bundle:clean</h2> |
| |
| <p>Sometimes you would like to clean your local OBR because it contains |
| bundles that are no longer in your local Maven repository. This case |
| often occurs when artifacts were deleted manually. The |
| maven-bundle-plugin provides a simple goal to check for missing |
| bundles, and remove them from the local OBR.</p> |
| |
| <p>configuration:</p> |
| <ul> |
| <li><em>obrRepository</em> path to local OBR, defaults to <em><local-maven-repository></em><tt>/repository.xml</tt></li> |
| </ul> |
| |
| |
| <p>Example:</p> |
| <div class="preformatted"><div class="preformattedContent"> |

| </div></div> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Concurrentupdates"></a>Concurrent updates</h2> |
| |
| <p>With a remote OBR, several uploads may occur at the same time. |
| However, the remote OBR is centralized in one file, so concurrent |
| modification must be avoided. To achieve this, the plug-in implements a |
| locking system. Each time the plug-in tries to modify the file it sets |
| a file based lock. If it can't take the lock, it will wait and retry. |
| After 3 attempts the upload process fails. To bypass this lock add <tt>-DignoreLock</tt> to the command-line (or add <tt><ignoreLock>true<ignoreLock></tt> to the configuration section of your Pom).</p> |
| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-FTPprotocol"></a>FTP protocol</h2> |
| |
| <p>Not all protocols are supported by Maven out of the box. For example the ftp protocol requires the <b>wagon-ftp</b> component. To enable the ftp protocol add this to your Pom:</p> |
| <div class="code"><div class="codeContent"> |
| <pre class="code-xml"><span class="code-tag"><build></span> |
| <span class="code-tag"><extensions></span> |

| |
| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Howtheplugincomputesthedescriptionofthebundle"></a>How the plug-in computes the description of the bundle</h2> |
| |
| <p>The description of the bundle comes from three different sources:</p> |
| <ul> |
| <li>Bindex : Bindex is a tool that analyzes a bundle manifest to generate OBR description</li> |
| <li>pom.xml : by analyzing the pom file, various information is collected (symbolic name ...)</li> |
| <li>obr.xml : this file contains customized description and capabilities for the bundle</li> |
| </ul> |
| |
| |
| <p>These sources are merged together using the following precedence:</p> |
| <div class="preformatted"><div class="preformattedContent"> |
| <pre>Bindex |
| | (overrides) |
| pom.xml |
| | (overrides) |
| obr.xml |

| <h2><a name="ApacheFelixMavenBundlePlugin(BND)-Knownissues&limitations"></a>Known issues & limitations</h2> |
| |
| <ol> |
| <li>obr.xml (file given by the user to add properties not found |
