Which version of kotlin gradle plugin

I’m trying to learn to use Gradle. I followed instructions here: https://kotlinlang.org/docs/reference/using-gradle.html

I’m not sure which version to use, but I wanted the latest kotlin, so I search here: https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-gradle-plugin

and that suggests that 1.1-M04 is available. But Gradle can’t find that version. Is it available?

thanks,
Rob

… duh, nevermind. I see I need to specify a different repository to get the 1.1 stuff.
