Yes there is. The KGP plugin registers an extension named `kotlin` of type `KotlinJvmProjectExtension`

Any idea how I might access it's `KotlinJvmOptions` configuration? I am attempting to move the code below from a build script configuration, via task lookup, into a conventional plugin. I can't easily see how I might be able to do this via the `KotlinJvmProjectExtension`

```tasks.withType(KotlinCompile::class).configureEach {
   kotlinOptions {
      allWarningsAsErrors = true
      jvmTarget = JavaVersion.VERSION_11.toString()

      sourceCompatibility = JavaVersion.VERSION_11.toString()
      targetCompatibility = JavaVersion.VERSION_11.toString()

      freeCompilerArgs = freeCompilerArgs + "-Xexplicit-api=strict" + "-opt-in=kotlin.RequiresOptIn"
   }
}```


Yeah configuring the extension is quite different than configuring the task.

It depends on the options. But from the top of my head something like `kotlin.target.compilations["main"]` will get you the compilation options for the main source set.

`kotlin.target.compilations.configureEach {}` should work if you want to configure them all

That seems to be what I was looking for, thank you for the help!

out of curiosity : are you releasing your convention plugins  or using includeBuild ?

At the moment I am using `includeBuild`, but may start releasing them to a private artifact repository later on

Thanks. I reverted the includeBuild because of the performance penalty our build incurred : the dependency resolution for all modules ended up being done single threaded. which aligns with the squad blog post and the documentation
