Eclipse: "'Periodic workspace save.' has encountered a pro‍blem."

I'm using Eclipse Indigo on Mac 10.7.4. While working, I get these periodic, annoying dialogs

'Periodic workspace save.' has encountered a problem.

Could not write metadata for '/.org.eclipse.jdt.core.external.folders'.
/Users/davea/Dropbox/workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/.org.eclipse.jdt.core.external.folders/.markers.snap (No such file or directory)

I seem to be able to continue as normal, but I was wondering how I can eliminate these errors.

The solution that work for me is the following:

  1. Delete .metadata folder
  2. Restart eclipse

Agree with @J-Dizzle,

I am a beginner in web-development and had a hard time solving this today. Had similar problems when I was creating a SpringBoot project in STS. Tried most of the solutions mentioned but they didn't work. Tried removing .metadata folder and re-building my springboot project but still nothing worked.

NOTE : I had multiple workspace in STS and this error occurred after migrating a project from one workspace to another.

Solution : All you need to do is restart your eclipse/STS IDE and it will work just fine.
