John Roesler commented on KAFKA-6474:
-------------------------------------
Yeah, thanks [~h314to]! I had tried it with just half of that change, and it
obviously didn't work. I'm really glad you figured that out!
FYI, there are other sub-projects in kafka that are going to follow this
pattern, so I'm going to start a dev mailing list discussion to share your
pattern.
Also, for completeness, I had to augment your build.gradle patch slightly to
get './gradlew streams:test-utils:test' to pass:
{noformat}

The reason is that we are skipping :streams:copyDependantLibs during
test-utils:compile now (to avoid the circular dependency), so we have to
explictly depend in testCompile on any libs that would have been transitively
pulled in from :streams (and are in the test's run-time code path).
In case you run into a similar error when you run the full test suite, the
error I saw was:
{noformat}
java.lang.ClassNotFoundException: org.rocksdb.RocksDBException{noformat}
