Once you have verified your path and permissions [no NFS], you would
address this as a a metadata issue:

  Fix List (for all the various iterations of this issue):

   1. In .metadata/, remove the .lock file
   2. If 1 doesn't work, try end process javaw.exe etc. then rm .lock file
   3. If 1 & 2 doesn't work, try remove the .log file in .metadata/, and
   double check .plugin/.
   4. This always worked for me: relocate .metadata/, open and close
   eclipse, then overwrite .metadata back

The solution involves cleaning up the .metadata folder with correct
contents!
