I think I see what is going on. After clearing the JTwork and JTreport directories, I was able to reproduce the failure. At least one of the tests looks to be missing a `@build` statement to check for dependencies.

Thanks for the thorough review; I'll correct the mistake in Tests and look over the build tags.
