Starting point: a heap of Java code built in Maven (and edited and debugged in Eclipse via the maven-eclipse-plugin). Desired end point: an Eclipse plugin that puts a UI around some of it. Question: What's the shortest path in terms of tools?
The maven-eclipse-plugin documentation suggests that it might have a contribution to make to the picture, but it's not clear to me that the functionality described is alive and kicking for current (3.5) Eclipse.
