[1.7.10] Duplicate paths in Eclipse

[HappyKiller1O1]

This is by far, the weirdest error I have ever seen. I was creating a hammer called "CrewHammer" (That's what the item class was called) and, the onCreated method in that class was getting called twice. So, I deleted that class to see if I accidentally used it to define another Item and, this happened:

 

 

Each path for an error was met with another path by eclipse to the folder on my computer. This glitch seems to be duplicating the item making it impossible to set NBT. The duplicate path says "org.eclipse.jdt.core.external.folders/[my file path to the class with the error]". Has anyone gotten this error before and knows how to go about fixing it?

Were you updating workspace, like just now?

Yes, after updating the workspace and I deleted the class that happened. After creating a new workspace and adding my .java's back to it; it seemed to fix it.
