Scapegoat not running in test only projects

[Green-Angry-Bird]

I have a project that has no source under src/main. All source is under src/test.

Running sbt clean test:compile I get the following output:
jonathon:~/devroot/BehaviourTests$ sbt clean test:compile
[info] Loading project definition from /home/jonathon/devroot/BehaviourTests/project
[info] Set current project to BehaviourTests (in build file:/home/jonathon/devroot/BehaviourTests/)

The scapegoat-report directory is not created.

I'm using sbt launcher version 0.13.7
My build definition uses Scala 2.11.5
