Is it possible to use Lombok with Kotlin?

Lombok does not run on your source code, but on the AST. Anyway, it is an annotation processor that is run at compile-time by the Java compiler. The Kotlin compiler does not use these annotation processors. See also the answer https://stackoverflow.com/a/35530223/2621917 straight from the horse’s mouth.

You cannot use annotation @Slf4j, but manually create its object in the class required.
