Hey everyone
I upgraded Kotlin Version to 1.9.20
But now in Shared Module build.gradle.kts, I’m getting these error on Sync

e: file:///Volumes/Files/Medial/MedialMultiplatform/shared/build.gradle.kts:18:5: Unresolved reference: androidTarget
e: file:///Volumes/Files/Medial/MedialMultiplatform/shared/build.gradle.kts:93:9: Unresolved reference: androidMain
e: file:///Volumes/Files/Medial/MedialMultiplatform/shared/build.gradle.kts:119:9: Unresolved reference: iosMain

This is my project Gradle

plugins {
    //trick: for the same plugin versions in all sub-modules
    id("com.android.application").version("8.2.0-beta06").apply(false)
    id("com.android.library").version("8.2.0-beta06").apply(false)
    kotlin("multiplatform").version(libs.versions.kotlin.get()).apply(false)
    id("com.codingfeline.buildkonfig").version("0.14.0").apply(false)
    kotlin("plugin.serialization").version("1.4.21").apply(false)
    id("org.jetbrains.compose").version(libs.versions.compose.get()).apply(false)
    id("com.google.gms.google-services").version("4.3.14").apply(false)
    alias(libs.plugins.crashlytics).apply(false)
}

this build files are not using the kotlin dsl. for getting the configurations you need to use something like val androidMain by getting

[Chrimaeon]

see one of the example apps. i.e. https://github.com/JetBrains/compose-multiplatform/tree/master/examples/imageviewer

[Vaibhav Jaiswal]

Even in Kotlin 1.9.20?

[Chrimaeon]

yes, your syntax is groovy.

[Vaibhav Jaiswal]

@Chrimaeon https://kotlinlang.org/docs/whatsnew1920.html#use-completion-for-source-sets

This shows we can use it without by getting

[Vaibhav Jaiswal]

It’s not detecting androidTarget too

[Chrimaeon]

It doesn’t say that this is Kotlin dsl.

[Vaibhav Jaiswal]

Okay, so I tried with getting this is what I get while syncing

After that, replace `by getting` with static accessors:

  sourceSets {
      commonMain { ... }
      
      iosMain {
          dependencies { ... }
      }
  }

[Chrimaeon]

then I’m out of ideas.

[Vaibhav Jaiswal]

No issues, thanks for helping out

[Chrimaeon]

what is the sentance before After that? did you doo that?

[Vaibhav Jaiswal]

to not use ios() and rather specify iOSArm64() etc ..

[Vaibhav Jaiswal]

These are just warnings

[Chrimaeon]

👍

[Jeff Lockhart]

This is correct, you can use static accessors for default hierarchy template source sets instead of by getting with Kotlin 1.9.20.

I'm assuming this:

commonMain {
    dependencies {
        implementation(kotlin("test"))
    }
}

is actually:

commonTest {
    dependencies {
        implementation(kotlin("test"))
    }
}

I'd make sure you're running the latest version of plugins and dependencies. In this case there was an issue because of the Build Konfig plugin, which it looks like you are using as well.

[Vaibhav Jaiswal]

@Jeff Lockhart I’ve tried by removing buildKonfig as well, commonMain and commonTest are wokring, but its still unable to detect androidMain and iosMain, as well as androidTarget

[dsavvinov]

It seems like for some reason you’re actually getting a version of KGP older than 1.9.20. This can happen if other Gradle plugins have “hard” dependencies on KGP and if they are not updated. It’s hard to be more precise without having a full access to buildscripts (settings.gradle.kts, convention plugins if any, etc.)

[Vaibhav Jaiswal]

The Android Studio version I’m using Hedgehog Beta 6, it has Kotlin Plugin 1.9.10, can this be the cause?

[Jeff Lockhart]

The Kotlin IDE plugin shouldn't affect the actual build.
