Eitan, I'm not sure this is really an m2e issue. The message "Launch configuration MyMaven references closed project MyMaven"
indicates that your "MyMaven" project references itself. If you go to Project -> Properties -> "Project references", such a selection should not be possible. I'd check the .classpath and .project files of the affected projects and see if you find a self-reference there.
