NetBeans UI support for Forge 2
$ mvn install $ cd application/ $ mvn nbm:cluster-app nbm:run-platform
works from command line. Of course, opening the sources in NetBeans IDE will give you more options than a command line.
At the end of your builder job you can call:
$ mvn nbm:autoupdate
which will generate target/netbeans_site/updates.xml catalog. If you publish it, users who add it into Tools/Plugins/Settings will be able to install your work into their existing NetBeans 8.0.x IDE.
