Answer 1

Sorry for grave-digging but I just stumbled across this while trying to achieve the same thing. Turns out that this has now been implemented, but requires a tiny configuration change.

So for any future adventures finding their way here: in your build.gradle to the following:

checkstyle {
  ignoreFailures = false
  maxWarnings = 0
}

This will then cause your builds to fail on Checkstyle errors.
