Upon restart it scans the metadata and sees this lock file, and as there is no pending task to clear it in the current instance, it awaits a deletion that will never happen. The problem occurs because Eclipse quits before it is able to delete a hidden “.lock” file in the workspace metadata. To be clear DO NOT DO ANY OF THESE!

The very worst recommends completely removing Eclipse and starting again. “Delete all of the hidden files in your workspace.”

“Delete your metadata directory and reimport.” “Delete your workspace and reimport your projects.” If you search for this problem you’ll see a lot of sledgehammer fixes suggested: This issue appears as you start Eclipse after an incomplete shutdown on a previous session – i.e.
