Solution

  • After trying to fix this multiple times, I finally resolved the issue. by doing the following: I removed eclipse. reinstalled eclipse. removed the metadata folder in my workspace. reinstalled eclipse etc

    It now works fine. I think it was some sort of corruption of the metadata folder. I am updating this to assist anyone else that might experience this strange issue.
