Hi any idea why I can not use kotlin 1 9 20 with compose mul kotlinlang #compose

This version (1.5.3) of the Compose Compiler requires Kotlin version 1.9.10 but you appear to be using Kotlin version 1.9.20 which is not known to be compatible.  Please consult the Compose-Kotlin compatibility map located at <https://developer.android.com/jetpack/androidx/releases/compose-kotlin> to choose a compatible version pair (or `suppressKotlinVersionCompatibilityCheck` but don't say I didn't warn you!).

Release notes say: Support Kotlin 1.9.20, see https://github.com/JetBrains/compose-multiplatform/releases/tag/v1.5.10

Yes, but compose compiler doesn't support Kotlin 1.9.20 yet (it's a different artifact)

The Jetbrains Compose compiler supports 1.9.20. @Jan are you also using the Jetpack Compose compiler?

Theoretically it should be selected automatically: https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-compatibility-and-versioning.html#kotlin-compatibility

Can you show your

build.gradle.kts

If you configure it inside the

android

block:

Copy code

android {
   composeOptions {
        kotlinCompilerExtensionVersion = "1.5.3"
    }
}

then it probably just takes the one from Google.

That's an example configuration of a Compose Multiplatform Android subproject https://github.com/JetBrains/compose-multiplatform/blob/master/examples/chat/androidApp/build.gradle.kts
