how do I delete an Eclipse project when I've already deleted the folder and contents?

Question

How do I fully delete an Eclipse project when I've already deleted the folder and contents? I want to do this so that I can reuse the project name.

Answer 1

Try removing directly the project within your workspace, within:

<workspace>\.metadata\.plugins\org.eclipse.core.resources\.projects\

as mentioned in "Where in an Eclipse workspace is the list of projects stored?"

Answer 2

In my case the project was completely removed yet still referenced in Eclipse. Thing is, the file holding the Working Sets configuration was the culprit. What I did was:

1. Shut down Eclipse
2. Open .metadata/.plugins/org.eclipse.ui.workbench/workingsets.xml
3. Find the faulty <item> tag and remove it
4. Start Eclipse

Answer 3

Don't have rep to comment directly on @VonC's answer yet. But here is how it worked for me.

1. removed the projects from <workspace>\.metadata\.plugins\org.eclipse.core.resources\projects\ As suggested above

2. Try to open each project, clicking "ok" to all th errors Now it seams it is gone, but if I try to import a new project with same name Eclipse claims they are still there.

3. in the project explorer press 'F5' to refresh. N ow eclipse realises the project is gone, and asks if it should remove the project from workspace, after accepting the project is now gone.

Maybe step 2 can be skipped, I have not tried.
