Try changing the workspace if it works. To force a change to a workspace prompt, make the following change.

 <Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true

  • If this works, go to the \ .metadata \ .plugins \ org.eclipse.core.resources workspace and delete the .snap file.

  • If # 2 doesn't work, try deleting the workspace \ .metadata \ .plugins \ org.eclipse.core.resources folder. Make sure you back up in case you need it in the future.

After about 30-45 minutes of hot testing, I found out that a .tree extension file was added to the% eclipse_workspace% .metadata.plugins \ org.eclipse.core.resources.root file. I uninstalled it and I was able to restart eclipse. Although all projects in my workspace have been deleted

Try deleting the .snap folder created in the plugins in the .metadata folder. for example, my workspace is in the location -> C: \ RawWorkspace \ .metadata will be in C: \ RawWorkspace.metadata p>

You may need to remove the .snap from the plugin - C: \ RawWorkspace.metadata.plugins \ org.eclipse.core.resources

I got an error for the Resource plugin. Therefore, I removed .snap from the resource plugin.

I ran into the same problem and tried a lot in my case, but one of the following:

  • just go to WorkSpace.metadata.plugins \ org.eclipse.core.resources.root
  • delete the * .tree file

Hope it works in your case - good luck.
