+Makefile will build also the apps. These are the apps currently integrated in the script: **trellis-control**, **up4** and **fabric-tna**. For each one, there is a **build** target.
 
 `appname-build` builds with the version specified in the `Makefile.vars.DOCKER_TAG`, using the following sources in order: (1) Maven central (for released versions or snapshots); (2) Local source code (for local branch not yet pushed); (3) Gerrit/Github (for pending review in the form of refs/changes/... or pending pull request). As a prerequisite, the script prepares `mvn_settings.xml` file, creates the `local-apps` folder and checks out the code if it is not present (relies on `appname` target). **APPNAME_VERSION**, defined in `Makefile.vars.DOCKER_TAG` file, can be overridden at runtime.
