I have a Kotlin Gradle project. I added Lombok as a dependency and also registred it with kapt
compileOnly("org.projectlombok:lombok:$lombokVersion")
kapt("org.projectlombok:lombok:$lombokVersion")
I would like to use just @Slf4j anotation for automatic log generation. It works for Java classes but not for the Kotlin ones.
Is using Kotling and Lombok together even possible as of now ?
EDIT: Adding more details
If I annotate a Kotlin classs with @Slf4j and use log inside it I get
Unresolved reference: log
Evidently no annotation processing is applied.
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.
Refer https://www.reddit.com/r/Kotlin/comments/8gbiul/slf4j_loggers_in_3_ways/
It's not supported and, by the looks of things, it isn't going to be.
If all you want to use Lombok for is @Slf4j, then I'd suggest using kotlin-logging instead: https://github.com/MicroUtils/kotlin-logging
I can't see how it would work without additional support from the lombok team. Lombok is based on annotation processing so it runs during compilation time and runs on your source code, so I guess it assumes Java's syntax.
