Karl-Heinz Marbaise commented on MEAR-212:
------------------------------------------

Could you provide a full working project which reproduces this problem. Apart from that {{ Unknown artifact type[mar] for addressing }} seemed to be the problem here.

> I'm trying to generate and ear file but I'm getting the following message:  Failed to initialize ear modules: Unknown artifact type[mar] for addressing  (full debug stack trace is below)
> However I don't have any mar artifacts in my dependencies.  What I do have is a war that has 4 mar files added as resources and I'm making a ear with the skinny war feature.
> Why would the ear plugin give this error when it has no nothing to do with the mar resources in the war...or perhaps this error has nothing to do with those resources, not sure.
