eclipse Invalid project name: Project “xxx” already exists.

For some reason, I manually delete a project in the workspace, or because of an exception when creating a project, I can’t see the name of a project in eclipse, but if I create the same project again, it will be reported that the name is invalid, and the project XXX already exists

Invalid project name: Project “xxx” already exists.

We can go to the workspace to delete the project information of XXX under the project information path (workspace. Metadata. Plugins. Org. Eclipse. Core. Resources. Projects), and then refresh the Project Explorer. In this way, eclipse will automatically rebuild the following project space, and then there will be no project of XXX, You can recreate the project XXX
