I wanted to make a top level enum class to use in my build.gradle.kts but i get an error saying

Don't know how to generate outer expression: Class: class MyClassName

. Is there a trick to using enum classes with the kotlin gradle dsl?

You could try putting it in buildSrc

hmm i dont run into that issue on gradle 4.9

just tested it out with gradle 4.9-rc-2 and it works fine now. interesting.

I didn't try to use it, I only tried it but declaring it. Their might be an open issue for that I don't remember
