Prebuild with Gradle: Could not find google-signin-support.jar

[tantzygames]

I'm not sure if this is an issue with Play Services Resolver or Google Sign In but I suspect it may have something to do with the recent change from arr to srcarr.

When I tried to prebuild with Gradle from Play Services Resolver I got the following error:

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring root project 'GenGradle'.

Could not find google-signin-support.jar (com.google.signin:google-signin-support:1.0.2).
Searched in the following locations:
file:/D:/Unity/Project/Temp/GenGradle/m2repository/com/google/signin/google-signin-support/1.0.2/google-signin-support-1.0.2.jar

Can you suggest a solution?
