Eclipse loops endlessly: Invoking 'Maven Project Builder'

Question

Ugh! My Eclipse is stuck in an endless loop:

• No operations to display at this time
• Refreshing Workspace Building
• Workspace. Invoking \'Maven Pro

Answer 1

I was getting the same issue in an eclipse (Juno) Maven project that had nothing to do with GWT - it just kept refreshing and "Invoking Maven Project Builder". Going to the Progress view and requesting a cancellation of either progress entry (by clicking that red stop button on the right) didn't help.

The project the builder kept getting stuck on was always the same, and a couple of levels deep in a set of multi-pom maven projects in eclipse.

What eventually solved it for me was just going into that particular project's Properties > Builders and unchecking Maven Project Builder (but keeping the Java Builder checked so that it would still auto-build when code changed). I just ignored the warning about this being an "advanced operation" and possibly having "many side-effects" - I figured it couldn't be any more annoying than that constant build-refresh cycle. I'm still not sure what the cause of this loop was, but that stopped it for me. And I haven't had any problems since.
