How can I target JVM 21 in a Kotlin 2.1.21 project?

jvmTarget.set(JvmTarget.JVM_21)

is an unresolved reference. JVM_20 exists but not 21.

Ah, perhaps I need Kotlin 2.2.0 for that.

You need Kotlin Gradle Plugin version 1.9.20 or later.

For completeness, you should probably use the same version for Kotlin and Kotlin Gradle Plugin.
