Just did that now. Waiting for his response.

@reidbaker the change in #3574 seems to have removed the package from this manifest. Was that intended, and is putting it back undoing what you were trying to do?

[reidbaker]

The package is now defined in the build.gradle. Please don't add this back in the manifest
