Investigate a way for better Eclipse integration

[dscho]

We do a pretty good job already, but the following scenario is still too hard to handle: if a developed opens two related projects in Eclipse, they are not automatically connected unless the versions match. However, almost always the developer wants them to be connected in such a case.

So far, we try to help the situation by having dev profiles, but they still need a lot of manual interaction, and are not bound to whether the projects are open in the same workspace.

Investigate how easy/feasible it would be e.g. to write an m2e plugin that helps with all this, bound to a mojo of the scijava-maven-plugin.
