This is caused by a version mismatch of some kind. Please make sure that all Kotlin-related dependencies in your build script have the same version 1.0.4. If you’re using Dokka, please ensure that you use version 0.9.9.
I’m not using Dokka, the only other plugin I use is anko and its updated to latest version 0.9
Please show your full build.gradle.
