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

This was happening to me after a project I cloned from GitHub changed its structure to multi-module Maven project. Since some eclipse-specific files were in .gitignore, doing git pull kept the originals even after I removed the old project from Eclipse and re-imported it as new with submodules. This apparently caused some chaos leading to the issue.

Nuking the project directory and re-cloning the project resolved the issue.
