回答1:
Try changing the workspace if that works. To force change workspace prompt, make following change.
<Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true
If that works, go to workspace\.metadata\.plugins\org.eclipse.core.resources and delete .snap file.
If #2 does not work, try deleting workspace\.metadata\.plugins\org.eclipse.core.resources folder. Make sure you back it up, just in case it is needed in future.
回答2:
After about 30-45 minutes of heat n trials i found out there was a file in %eclipse_workspace%.metadata.plugins\org.eclipse.core.resources.root by extension ".tree". I removed it and it i could restart eclipse. Though all projects in my workspace got deleted
回答3:
Try deleting .snap folder created in plugins under .metadata folder. e.g. my workspace is at location -> C:\RawWorkspace\ .metadata will be at C:\RawWorkspace.metadata
You might need to delete .snap from below plugin - C:\RawWorkspace.metadata.plugins\org.eclipse.core.resources
I got error for Resource plugin. So I deleted .snap from resource plugin.
回答4:
I face the same issue and try many but one of the following worked in my case:
- just navigate to WorkSpace.metadata.plugins\org.eclipse.core.resources.root
- delete the *.tree file
Hopefully it work in your case - good luck.
回答5:
Deleting the .snap file works for me when i got the same issue as mentioned in the original post. workspace.metadata.plugins\org.eclipse.core.resources and delete .snap file.
Thanks!
回答6:
I had this same problem, option 1 from user1401472s answer worked for me Restoring the projects from the corrupted workspace was as simple as re-importing them from the old workspace into the new workspace via: file -> import -> General -> "Existing Projects From Workspace" and selecting the old workspace folder as the root-directory.
EDIT: this was on windows 10
