Plugin

[dubinsky]

• [ ] add new tags to the plugin's portal page: manually at https://github.com/gradle/plugin-portal-requests !
• [x] switch to the new plugin publishing plugin if I can figure out how to use my signing properties;
• [ ] look at the https://github.com/helmethair-co/scalatest-junit-runner;
• [x] consider splitting the plugin into sbt testing and ScalaJS - why bother?

Compare and contrast with the ScalaTest Gradle plugin in my README:

• [ ] https://github.com/maiflai/gradle-scalatest/issues/69
• [ ] https://github.com/maiflai/gradle-scalatest/issues/67
