Is it only me or the warning for beta expect/actual classes won't ever go away, no matter which flag I set.
IDEA 2023.3 EAP (latest) and 1.9.21

tasks.withType<KotlinCompilationTask<*>>().configureEach {
    compilerOptions {
        freeCompilerArgs.add("-Xexpect-actual-classes")
    }
}

I have this in shared:build.gradle and warning is gone

This is the way I had to do it in 1.9.20, based on this thread. Kotlin 1.9.21 introduced a language feature option to address this issue with the IDE not picking up the compiler flag.

1.9.21 has partially returned compiler options DSL in extension, so following should work:

kotlin {
    compilerOptions {
        freeCompilerArgs.add("-Xexpect-actual-classes")
    }
}

Thanks @tapchicoma, this looks a lot cleaner.
