Had to write some custom Version.java generation code for the TestNG build recently. You have no idea how liberating it was to just write five lines of Kotlin and put them in my build file verbatim. No silly groovy or having to understand what the DSL means and how to use it: just pure straight Files.copy kotlin code in my build file. And it worked instantly.
