@hoisie could you help to review this PR? Thanks.

Thank you so much for doing this. What's the best way to test this before merging it? I just want to make sure that the existing CircleCI checks can continue to run until these Github checks stabilize.

I've tried testing it before, and you can see https://github.com/LitterSun/robolectric/actions, I also tested some error cases.
I agree with keeping CircleCI checks until these Github checks stabilize.

Thanks again! Can't wait to get this up and running!
