Got gradle to work and tests working again for the most part.
Added a better message for what's expected of TestConstants
Even DRYer TestConstants
Forgot to add the 'gen' folder to the tests source.  Now those get run as well.  Fixed a few things that were essentially typos.
Added gradle wrapper jar.  Just call gradlew test and you don't need to install Gradle anymore.
