Trouble accessing SonarQube Gradle Plugin

Using the docs Gradle Plugins Sonarqube in my build.gradle (I have tried both apply models {using the buildscript and the new plugins block})

I run ./gradlew build getting this error:

FAILURE: Build failed with an exception.

Could not resolve all dependencies for configuration ':compileClasspath'.
