Thread: Eclipse Error: Could not open the editor: The file does not exist?

Hello everyone, I have been using Eclipse as a Java IDE for a while now and came to my first big problem. I have been creating a game for a few months now with no problems, now when I run eclipse and try to open my project and it's classes I receive an error 'Could not open the editor: The file does not exist.'

I check the details: 'org.eclipse.core.runtime.CoreException: The file does not exist.

I have never played around with any of eclipse's files nor deleted any. The files are still in both the .src and .bin files of my project within the workspace folder. What has happened? Is there any way to fix it? It would be heartbreaking if not as I spent quite a lot of time creating it. I do have some back up .txt files of earlier revisions of code though.

Any help on resolving this issue would be appreciated, thanks!!

First, right click the parent folder/package and hit refresh. Then check the actual hard drive location of the file(s) - I believe the default is within the workspace folder in your home directory. The file could be gone, but the tree not refreshed to show this. If its gone check your trash - Eclipse would not have trashed the file unless told to do so, and it would have updated the tree to reflect this.

Based upon what you said in post #3 they do exist.

When I say refresh, I meant in the Project Explorer view. I would also a) backup your project b) clean/rebuild the project c) restart Eclipse.

Oh ok, thank you! I managed to fix it, for some reason I needed to create the project again with the same name? I don't know why but it worked, all my classes are restored. Eclipse must have lost the path to my files.
