Zoltan>if I run the java compiler it cames back complaining that it doesn't know what the testkt is.
In other words, Kotlin compiles *.kt files, and javac compiles *.java files. As for me it looks great. Zoltan>But still: are there any benefits that kotlin is added to the core module? Some of them are highlighted in CALCITE-2458 description. On top of that, having "core" tests in "core" module simplifies development flow: one can run tests from within IDE (e.g. hack relevant class and run relevant test), one can just use `mvn test` to run the tests, and so on. Building "just two modules" with maven is a pain. Maven modules are processed sequentially, so adding more modules would pile up overhead. Then there's "release artifacts", and what sense would it make "core-tests" artifact published to Central? Vladimir
