The idea is to develop plugins so that most (if not all) the work is performed in a regular jar artifact... that way, to extend the plugin you just depend on the jar file not the plugin. What you therefore want to do is ensure that the plugin you need to extend is refactored so that 99.9% of the code in the mojo is moved into a separate module, then you just depend on that module. > > > Thank you. > > --------------------------------------------------------------------- > > To unsubscribe, e-mail: users-unsubscr...@maven.apache.org > > For additional commands, e-mail: users-h...@maven.apache.org > > > > > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@maven.apache.org > For additional commands, e-mail: users-h...@maven.apache.org > >
