Answer 1

In my case, for some reason, Android Plugin Version wasn't set. I did try clearing cache and removing .gradle and .idea as well, but it didn't work out and after finally wandering for hours, I found this.

Answer 2

For me, I refer a jar in a module library. It cannot resolve the symbol in the jar. So I find the solution for my situation. Use the provided way.

provided fileTree(include: ['xxx.jar'], dir: '../moduleX/libs')

Answer 3

It seems that everyone uses a different approach for getting around these issues. I'll suggest another one that I feel is a bit less invasive than the others. When I introduce changes from an aar library that I include, I will open up the "settings.gradle" file for the project.

Then cut out the main project module from the list of projects:

include ':mainproj',

and then sync your project. Then paste it back in and re-sync your project once more. I believe that this is the same as some of the manual deletion steps, but this lets you do so from the IDE a bit quicker and less painfully.
