Somes files that are in .gitignore are still in the repository
This will remove them.
Commands used to do this:
git rm --cached -r . &&
git add . &&
git restore --staged .gitmodul
The jars in src/java/JavaFileStorage/libs are no more used since commit
a63663c30e
If this removes too many files, it means that .gitignore has to be fixed.
To find which rule removes which file run:
git check-ignore -v <file>
Especially, removing .idea/ completely might not be correct depending on ones
objective.
