To build on Anton's reply... check if your Maven goals change something on
the classpath (src, not target, to be clear), which is then picked up by
Eclipse and triggers a rebuild.

I work on a project where the Maven setup is so messed up that the resource
cycles might not only change files on the classpath, but even the actual
classpath itself. I regularly wait 30min or more for Eclipse to finish
building.
