Can't build for Android?

[bigtunacan]

My project builds fine for Android until I try and add the HeyZap extension, then the build fails with this error

Could not find play-services-ads.jar (com.google.android.gms:play-services-ads:12.0.1).
  Searched in the following locations:
      https://jcenter.bintray.com/com/google/android/gms/play-services-ads/12.0.1/play-services-ads-12.0.1.jar

I have carefully gone over the HeyZap documentation multiple times and followed it step by step to no avail.

I also found this article on Stack Overflow that seems very related.

This makes me think there is and issue with the Gradle file that is being created; how might I make updates directly to this file?

Perhaps related to this article that YYG have posted about in the Announcements:

I'm only guessing as I don't build for Android, but as it is to do with not finding services I thought it may be related.
