Eugene Kuleshov commented on MWAR-192:
--------------------------------------

Guys, you can call this an m2eclipse bug or feature, but it all boils down to the current Maven and maven-war-plugin limitations.

What happen is that m2eclipse can resolve projects from the Eclipse workspace, so you can compile and run your code without deploying dependent projects to the Maven local repository. Normally, when Maven resolves artifacts it points to the file from the Maven local repository, but in order to make workspace dependency resolution work, m2eclipse replaces that link to a link pointing to a /target/classes folder for the corresponding project (you can see that in the exception stack trace above).

All in all, there is no easy fix for this issue on m2eclipse side, however the maven-war-plugin could detect that it got a class folder and not the jar file for the given artifact and in that case it can simply jar that folder and include the result jar into the web-inf/lib instead of trying to blindly copy it there.
