Pushing code from Maven builds into Eclipse plugins

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 documen开发者_运维百科tation 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.

You can use Tycho.

Why do you need "an Eclipse plugin that puts a UI around some of it" when there is already m2eclipse ?
