@yan there was something going wrong with my IntelliJ as I switched to a different machine and just adding plugin as described in the https://discuss.kotlinlang.org/t/kotlin-1-0-6-eap/2117 worked for me. This is example project I tested against https://github.com/pbartoszek/kotlin-allopen. So it looks like Intellij needs to detect somehow that compiler plugin is defined in pom and run it behind the scene...
