Eclipse is in the unresponsive status after it is opened

After eclipse is turned on, it is in the unresponsive state, and the change is not reflected, and the CPU usage is 0. It should be caused by abnormal shutdown and incorrect file status in the eclipse workspace.

Solution: In the workspace directory, There Is A. Metadata Directory, which contains information about the workspace and various plug-ins. Deleting this directory can solve the problem.

For the sake of insurance. you can restart eclipse after renaming metadata to the/tmp directory. However, the configuration and project information of the original workspace disappear, and the welcome interface is displayed directly.

How can I restore the original project configuration? I tried to compare the current. Metadata directory with the one I backed up and found that many configuration files were missing. Try to restore some directories a little bit, but the effect is not satisfactory. It is because you do not know which files (directories) can be restored and which ones will cause problems. How can I restore the entire backup directory? Eclipse returns to the unable to start status again.
What should I do? The following figure shows the status of the start and stop: "loading workbench". It seems to be related to this workbench plug-in. Check the original. Metadata/. plugins directory and find the following two folders: org. Eclipse. UI. workbench and org. Eclipse. UI. workbench. texteditor.

Delete these two directories and restart eclipse. Started properly and the original project information is loaded correctly.
