This is the one I meant as unspported
2. The second trying was using Maven Archetype 
3. The third trying was using Plugin Generator
I know what you mean - I've meanwhile changed this to contain a dummy property.
Isn't it strange a generated code not deploying correctly?
This is unfortunately a tradeoff between comfort (generate (dummies for) everything ) and being annoyed by
the generator asking hundreds of questions. Some people rather want to open rhq-plugin.xml in vi and edit
some stuff, while others just want everything being asked.
But thanks a lot for your feedback.
