How to undo 'Do not ask again' for Clear unused output directories?
Answered
When opening a project (that was regenerated outside of idea for instance) sometimes I got the pop-up message like:
Clear unused output directories to free up a disk space: Clean up / Do not ask again
I accidentally clicked "Do not ask again". How do I revert this option? I couldn't find it in the settings.
Thanks

IDE creates a marker file after cleanup or selecting "Do not ask again": idea.system.path\compile-server\<project_name>_<hash>\stale_outputs_checked. Delete this file if you want IDE to suggest the cleanup again. This operation is needed only once to clean the old output directories caused by this bug: https://youtrack.jetbrains.com/issue/IDEA-185574 .
Since this bug is already fixed, you do not need to do it again once already cleaned for the current project.
