Since the test JARs are built from source code (in test/java), we're
probably fine to just include them, but I wasn't sure if there's any paperwork
needed. @joewitt Think these are fine as-is? I believe so but wanted a second
opinion. An alternative could be to set the Module Directory to point at the
target/classes directory, that should allow them to be loaded but not have to
be in a JAR.
