cannot import gradle project
Answered
I am trying to just get started from zero by running the Kotlin Koans from here https://kotlinlang.org/docs/tutorials/koans.html.
I have gradle installed
I clone the repo and try to import the project, getting this error
When I open the gradle settings, all options are greyed out, so I don't see any way to fix anything.
Would be grateful for any advice.

You should be able to specify Gradle JVM here:
That option is greyed out because there is no linked gradle project. It's a chicken-egg: I can't import the gradle project because there is no Gradle JVM, and I can't set the Gradle JVM because there is no gradle project :(
Try creating a new Gradle project from scratch, there will be options to specify the JVM.
You can also try adjusting your JAVA_HOME to point to JDK instead of JRE.
That (creating a new Gradle project) ungreyed the options in the koans project! I'm grateful!
