Gradle sync failed: Gradle DSL method not found: 'compile()',Consult IDE log for more details (Help | Show Log)

Question

I am currently trying to learn how to use Google services apk, and tried one of their samples called Buttonclicker where i can learn how to use their multiplayer apk.

However after following all the instructions, i got the error,

Gradle sync failed: Gradle DSL method not found: 'compile()'
            Consult IDE log for more details (Help | Show Log)

I have tried looking at similar stackoverflow pages but i cant seem to find any solution to it.

I suspect this has to do with the gradle but i am not sure where i have gone wrong

This happenned after i have generated my apk, and i headed on to try to get the signing done whereby i set the build types to release after doing all the required steps.

Gradle file
