Newer versions (6ish or so) have introduced a SonarKotlin plugin, so they're working on native support of Kotlin. Simplifies configuration of Sonar for scanning Kotlin code.
I believe it will also display results from Detekt, but it's been awhile since that update took place, so I don't recall specifics.
