Hi guys,
I'm working on a web API that uses Kotlin and Spek and every time that I try to build my project using Gradle I'm getting the following error:

Exception in thread "main" java.lang.AbstractMethodError: Method org/jetbrains/spek/engine/Scope$Group.getType()Lorg/junit/platform/engine/TestDescri

Does anyone knows how can I solve or work around this problem in order to make the build process works properly?
