I'm not sure if this is the same problem that you have, but a while ago 
I had some problems regarding facets being loaded.

I assume that your UndoFacet (interface and implementation) are in the 
same project that you are executing 'forge source plugin' on, if they 
aren't, then they should be (or you will need to run 'mvn clean install' 
to add those JARs to your local Maven repo).

As well, I had problems using the group ID 'org.jboss.forge'.  Any 
dependencies in my plugin with this group ID were assumed to be part of 
the core, and Forge would mark these as scope provided and cause some 

Once again, I don't think these problems should occur if UndoFacet and 
its implementation are in the same project as UndoPlugin, but just an 
idea of something to look for.
