Android Wear Project Gradle Sync Fails
Had the same problem. Open up your Android SDK manager, go to tools -> manage add on sites, and add your own repo:
https://dl-ssl.google.com/android/repository/addon-play-services-5.xml
I finally found these helpful guides. There are lots of broken links and bad info floating around, but these should work:

Also, double check your android sdk manager to make sure you have all the latest updates, as well as the android support repository/libraries!
All the suggestion here at SO are now outdated.
What you should do is make sure "Google Repository" is checked and installed in the SDK manager.
If all of these didn't work for you, check out the instructions at https://code.google.com/p/android/issues/detail?id=72454For me, I was simply missing Google Repository from the extras section in the sdk manager
