In Kotlin 1.9.20-Beta, what's the correct way to pass a compiler flag (in an mpp project)? I currently have:

val extension: KotlinProjectExtension = ...
extension.targets.forEach {
  it.compilerOptions.freeCompilerArgs.add("-Xfoo")
}

I would advice you to try this new DSL

[tapchicoma]

if you want to do it in convention plugin - then please use KotlinMultiplatfromExtension.compilerOptions { ... } or KotlinMultiplatformExtension.compilerOptions.optIn.add(...)

Thank you! Yep I wanted to do in a convention plugin, and this works ☝️
One aside is that I have a shared function for both KotlinMultiplatfromExtension and KotlinAndroidProjectExtension and wished I could apply there (through the common type KotlinProjectExtension), but I just need to pass -Xexpect-actual-classes and this might not be necessary for kotlin-android modules, I think?

[tapchicoma]

I suspect - not - it is not needed for Kotlin/Android project as there is no common code
