				32	as a big collection of classes (e.g., project code, dependencies, and
				33	the class path). The way you create a bundle with BND is to tell it the
				34	content of the bundle's JAR file as a subset of the available classes.
				35	This plugin wraps BND to make it work specifically with the Maven 2
				36	project structure and to provide it with reasonable default behavior

				123	<p>The <tt><Export-Package></tt> instruction is a list of
				124	packages for the bundle to export. These packages are copied into the
				125	resulting bundle JAR file from the available classes (i.e., project
				126	classes, dependencies, and class path); thus, it is possible to include
				127	classes into your bundle that are not associated with source files in
				128	your project. <tt><Export-Package></tt> can be specified with
				129	package patterns using the '*' wildcard. Also, it is possible to
				130	exclude packages using negation by starting the package pattern with
				131	'!'. Thus, non-negated patterns indicate which of the available
				132	packages to include in the bundle, whereas negated patterns indicate
				133	which should not be included in the bundle.</p>
				134
				135	<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>
				136
				137	<p>Following standard OSGi R4 syntax, package patterns can include both
				138	directives and attributes, which will be copied appropriately into the
				139	generated Export-Package manifest header. Besides explicitly listing
				140	package version attributes, BND will also determine package versions by
				141	examining the source JAR file or from <tt>packageinfo</tt> files in the package directory.</p>

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>
				165	form will place the resource in the bundle JAR with only the file name,
				166	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>
				167	points to a directory, the entire directory hierarchy is copied into
				168	the resulting bundle JAR file relative to the specified directory. If a
				169	specific resource must be placed into a subdirectory of the bundle jar,
				170	then use the <tt>assignment</tt> form, where the first path is the the
				171	destination path (including file name if the resource is a file) and
				172	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>
				173
				174	<p>If a resource clause is specified inside of "{ ... }" brackets, then
				175	variable substitution will be performed on the resource, where
				176	variables in the resources are denoted with "${ ... }" syntax.</p>

Stuart McCulloch	7c961f5	2008-01-02 08:56:07 +0000	[diff] [blame]	178	<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.

				182	<p>The <tt><Import-Package></tt> instruction is a list of

				186	in certain cases when there is an unwanted import, such an import can
				187	be removed by using a negation package pattern. The package patterns
				188	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>

				761	<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.

				762	instructions will result in classes being inlined in the bundle, even
				763	though they also exist inside the embedded jar. If you want to export
				764	packages from an embedded dependency without such duplication then you
				765	can either inline the dependency, or use a new BND instruction called <tt><_exportcontents></tt>.</p>

				1084	<p>Sometimes you would like to clean your local OBR because it contains
				1085	bundles that are no longer in your local Maven repository. This case
				1086	often occurs when artifacts were deleted manually. The
				1087	maven-bundle-plugin provides a simple goal to check for missing
				1088	bundles, and remove them from the local OBR.</p>
				1089
				1090	<p>configuration:</p>
				1091	<ul>
				1092	<li><em>obrRepository</em> path to local OBR, defaults to <em><local-maven-repository></em><tt>/repository.xml</tt></li>

				1104	<p>With a remote OBR, several uploads may occur at the same time.
				1105	However, the remote OBR is centralized in one file, so concurrent
				1106	modification must be avoided. To achieve this, the plug-in implements a
				1107	locking system. Each time the plug-in tries to modify the file it sets
				1108	a file based lock. If it can't take the lock, it will wait and retry.
				1109	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>
