Resource/xxxx does not exist

Yesterday, several jar files were directly deleted under the project folder, and the resource/xxx Dees not exist prompt is displayed when you come back and run the project. after analyzing the cause, it should be because a jar is deleted outside, eclipse does not know yet, and WebProgramWhen I thought that the jar is still there, I published it, but the file does not exist, so I reported an error.

The solution is simple. Refresh the entire project and you will be OK.

One lesson is to delete as few jar files as possible. You 'd better delete them under the Web library. If they are deleted, remember to refresh the project.
