PR title says '..in benchmarks module', but you actually migrated to compilerOptions everywhere, right?

[sandwwraith]

It wasn't here before, why is it needed?

[qwwdfsad]

In master (2.0.20), KGP requires toolchain and and jvmTarget to be consistent. Otherwise, things like org.gradle.api.InvalidUserCodeException: Inconsistent JVM-target compatibility detected for tasks 'compileTestJava' (1.8) and 'compileTestKotlin' (11). pop up

Hm, given that we have both options.release = 8 in JavaCompile and freeCompilerArgs.add("-Xjdk-release=1.8") in KotlinCompile, do we actually need toolchains?

[sandwwraith]

Since you've added jdkToolchainVersion as a property, this block on line 21:

java {
    toolchain {
        languageVersion.set(JavaLanguageVersion.of(11))
    }
}

probably should use it as well instead of JavaLanguageVersion.of(11)
