Thanks for the pull request.

Did you get this to work without breaking Android Studio's instant run?

[msfjarvis]

I don't use Instant Run but I don't see how anything here would break it.

That should work.
@MSF-Jarvis any reason for gradle 4.6 vs 4.8 (or 4.10.2?)

I get this when trying to run with Instant Run enabled:

SHA-256 digest error for org/eclipse/jgit/transport/CredentialsProvider.class

@zeapo I wasn't sure about the policy on alpha plugins with the project, I'll go bump everything to the latest available in a few.

@zidhuss no idea about that, will try to see if there's something I can do on my end. Did you try invalidating caches? Instant run is notoriously annoying about build caches :(

[zeapo]

@MSF-Jarvis I don't think (maybe I'm wrong) that we need the alpha on the plugin to be able to use a 4.8 or 4.10 (https://developer.android.com/studio/releases/gradle-plugin#3-2-0)

[msfjarvis]

Ah, true. Will downgrade the plugin back.
