At present, there is no correct solution on Google. This is a very simple mistake. The reason is that the jar package source attachment: Specifies that you do not have a drive letter. Just delete it and it's OK. This function is to specify the source path.

The advantage is that you don't have to delete the project at all and recreate it.

For projects already in operation, it's very troublesome. This method can be solved.
