Maven plugin for creating NetBeans modules. It defines a custom lifecycle called "nbm". During packaging, the module JAR is enhanced with NetBeans-specific manifest entries and, along with other required files, packed into a *.nbm file, ready for distribution. Additionally the plugin provides aggregator goals to create an update site or cluster for your module projects.
The newest version!
