Maven Archetype Modularity

["Piwoni, Andre" <ap...@obsglobal.com>]

I have one archetype A which can be used to generate project B with module C and module D. I also need capability to generate second, third etc. module C that could be added to existing project B.
How could I reuse module C definition in both cases? I could possibly create one  archetype for module C and one for module D as partial, if this would work? But would there be a way to reuse these archetypes by another archetype that can generate module C and D?

Thanks,
Andre Piwoni
