M2 or M3? For M2 the first error is normal, since every plugin is loaded once and once only. If the first usage of the assembly plugin does not contain your handler as part of its classpath, it will not be available anywhere else in the multi-project build. M3 should instantiate the plugin again with the proper CP. - Jörg --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
