kotlinlang

We have a problem after upgrading to 2.1.20
We get the following error when running using JDK 17:
&gt; KotlinLibraryConventionPlugin has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0
&gt; 
Is JDK 21 required to target Kotlin 2.1.20?

Looks like your build logic convention plugin is targeting Java 21 maybe?

Do you have a toolchain setup or anything like this in `build-logic/build.gradle.kts` (or `buildSrc/build.gradle.kts`)?

It turns out I had to do a clean to reset the build config cache :sweat_smile:

Good old "off and on again" solution :sweat_smile:

That's probably a bug in the caching logic somewhere though. If your Gradle JVM changes, and you're not specifying a toolchain/target explicitely, I would have expected the build logic to recompile the convention plugins :shrug:

Yeah, that's a valid point, I'll see if there's a bug report on gradle
