The plugin is capable of populating the local or remote maven repository with module jars and NBM files from a given NetBeans installation. Useful for module development, modules with public APIs are separated from those without a public API. See the populate goal and the HOWTO document for details.
To get access to a repository with NetBeans.org module artifacts and metadata, add http://bits.netbeans.org/maven2/ repository to your project POM or the repository manager you are using. The repository hosts binaries of NetBeans 6.5 and later.
