Hey @colorant I just looked around some more. Earlier we were getting errors when publishing artifacts that look like this:

    'groupId' contains an expression but should be a constant.

This is something new in Maven3 - it requires group ID's to be constants. That said, I looked into this a bit more and I think it only applies to the top level group being declared in the pom, not the group used in dependencies. So I agree we should make this a property.
