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 opened my module's .project file. There were two entries:

  org.maven.ide.eclipse.maven2Builder


  org.eclipse.m2e.core.maven2Builder

I removed org.eclipse.m2e.core.maven2Builder entry and it magically fixed the problem.
