'Building workspace' has encountered an error

I ran into this same issue and I believe the culprit to be the Sonarqube plugin I had installed.

This discussion pointed me in that direction:

Uninstalled the Sonarqube plugin and the error is gone.


Try next steps:

  1. Go to your eclipse installation folder
  2. Run "eclipse.exe -clean"
  3. Work normally
  4. Enjoy

I uninstalled my Netbeans because Eclipse and Netbeans are both usin the same workspace.

i uninstalled Netbeans and the error is gone.
