Deleting metadata folder might not work in this case  Or eclipse -clean command  Or reinstall eclipse might not solve this   Instead try deleting other java versions you might have in your machine    Check what you have right now using this    usr libexec java home -V   Delete other java versions which you don t want  following below command   sudo rm -rf  System Library Java JavaVirtualMachines java-version jdk   This should resolve your issue
