Cant apply Kotlin Gradle plugin v1.7.20 on JDK 19

[daniel-jasinski]

When using the latest nightly build of Gradle with the latest Kotlin version (1.7.20) on JDK 19 build fails during Kotlin plugin dependency resolution.

Expected Behavior

Gradle should be able to configure the project on JDK 19 with Kotlin 1.7.20.

Current Behavior

Project configuration fails with the following errors:

A problem occurred configuring project ':buildInclude'.
Could not determine the dependencies of null.
Could not resolve all task dependencies for configuration ':buildInclude:classpath'.

Thank you for your interest in Gradle!

This issue lacks information and/or a reproducer to track down the problem. Unless you provide that information over the next 7 days, this issue will be closed.

You can use the following as a base for your reproducer: https://github.com/gradle/gradle-issue-reproducer

The error looks like an incomplete setup, but it is hard to say what is missing exactly without a reproducer.

I can reproduce this with this minimal sample:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.20")
        classpath("org.jetbrains.kotlinx:atomicfu-gradle-plugin:0.18.4")
    }
}

Reproducer: https://github.com/Prototik/gradle-bug-22440

Removing atomicfu plugin or changing kotlin plugin to 1.7.10 fixes the build.

Actually atomicfu maintainers aware of the issue: Kotlin/kotlinx-atomicfu#248.
But still message not clear and intuitive anyway.

See #22510
