I used to view resources of external libraries in the Project Panel of Android Studio. But somehow for one of my projects the res directory is not visible in Project Panel > External Libraries > lib name

Only AndroidManifest.xml shows in the panel, and it has weird icon. When I hover the icon with cursor a popup appears: "Excluded from compilation".

How it used to look (screenshot from another project):

How it looks now:

I followed the steps from "File > Repair IDE" but with no success. One part of it was "Invalidate caches and restart" and it wasn't solution for me.

It seems that I changed some setting, but I don't know which one has to do with this issue.

What worked for me was ensuring that .gradle is NOT in the list of ignored folders.

The setting is located in Preferences → Editor → File Types → Ignored Files and Folders
