Shot: NullPointerException when there are no screenshot tests

I’m running the plugin like the documentation says, and am getting this exception. I’m following it through and it looks like the plugin is trying to get screen shots for compose and there are none so there is a NPE.

Caused by: java.lang.NullPointerException
