Some projects cannot be imported because they already exist in the workspace error in Eclipse

Question

I am trying to import a project that me and my co-worker have been working on.. and keep getting this error after I select-- \"import\" then \"import existing project\" then

Answer 1

In my case, I copied one of the projects (say 'Project1') from the workspace and pasted it to the same workspace. After that I modified the name of the pasted project (say to 'Project2'). I could not see it in the repository.

The main reason was .project file from the new project still had: Project1 instead of Project2.

So, I did following things in order to get the issue fixed:

1. Cut and paste Project2 outside the workspace
2. Change .project file to have Project2
3. Try importing Project2 again.

It worked for me.
