Failed to resolve two packages while trying to gradle sync.

[n3at-fr33k]

Following the Codelab and such, and can't get past the very first steps, of running the test app to see nothing happening. The build won't finish, because I get the following errors:
Failed to resolve: play-services-basement

Failed to resolve: play-services-measurement-base

The steps I did before this included:

1. Opening the project, and following this prompt:
   Unregistered VCS root detected The directory C:\Users\bcook\friendlychat-android is under Git, but is not registered in the Settings. Add root Configure Ignore
   I clicked Add root. Then, it re-ran the Gradle Build, and then failed.

This should be fixed by some recent updates. Sorry for the (incredibly) slow response here!
