How could I pass compiler args in a multiplatform repository? e.g. on my root `build.gradle`:

allprojects {
  tasks.withType(org.jetbrains.kotlin.gradle.dsl.KotlinCompile).configureEach { task ->
    task.kotlinOptions {
    }
  }
}

but this errors with

Execution failed for task ':mymodule:runCommonizer'.
> Could not create task ':mymodule:compileKotlinIosArm64'.
   > Cannot query the value of task ':mymodule:compileKotlinIosArm64' property 'compilation' because it has no value available.

note mymodule has the multiplatform plugin applied

Try exact same thing in afterEvaluate { } block

[leandro]

the error changed, good sign I guess, now i get:

> Could not create task ':store:compileDebugKotlinAndroid'.
   > Project#afterEvaluate(Closure) on project ':store' cannot be executed in the current context.

[leandro]

note, i added as:

tasks.withType(org.jetbrains.kotlin.gradle.dsl.KotlinCompile).configureEach { task ->
    afterEvaluate {
      task.kotlinOptions {
      }
    }
  }

[Big Chungus]

Ah, afterEvaluate needs to wrap your tasks invocation

[Big Chungus]

Basically top level

[leandro]

oh, I get the same error as before (the first one), with

afterEvaluate {
    tasks.withType(org.jetbrains.kotlin.gradle.dsl.KotlinCompile).configureEach { task ->
      task.kotlinOptions {
      }
    }
  }

[leandro]

No, apologies. It’s similar, but in a different task:

Cannot query the value of task ':mymodule:compileIosMainKotlinMetadata' property 'compilation' because it has no value available.

[Big Chungus]

How about this:

allprojects {
  afterEvaluate {
    tasks.withType<org.jetbrains.kotlin.gradle.dsl.KotlinCompile> { // this == task
      kotlinOptions {
      }
    }
  }
}

[Big Chungus]

If that doesn;t work you can try swapping the order of allprojects and afterEvaluate

[leandro]

No dice. But I changed the < and > to parenthesis because I’m editing a .groovy file, not kotlin. But still, same error 😞

[leandro]

so basically

allprojects {
  afterEvaluate {
      tasks.withType(org.jetbrains.kotlin.gradle.dsl.KotlinCompile) { // this == task
          kotlinOptions {
          }
      }
  }
}

[Big Chungus]

Hmm, then I'd suggest you writing the logic you want to reuse in buildSrc and apply it to each module individually

[Big Chungus]

allprojects can often be flaky due to script resolution dependencies, unfortunately

[Big Chungus]

You might also try using .kts gradle scripts. But that's just a wild guess with no guarantees to work.

[leandro]

Oh I figured 🤦 it seems I was using an old task, the right one is tasks.KotlinCompile instead of dsl.KotlinCompile

[Big Chungus]

can you post your final solution here for future explorers?

[leandro]

absolutely. that would be:

allprojects {
  tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach { task ->
    task.kotlinOptions {
    }
  }
}
