IDE shows unresolved references for MPP Compose in androidMain source sets

[arkivanov]

This happens for me for a couple of months already. All MPP Compose references are red (unresolved) in all androidMain source sets in all IDEs. Other KMP libraries work fine. Everything compiles just fine.

Kotlin 1.7.0, 1.7.10 Compose 1.2.0-alpha01-dev753, 1.2.0-beta01 Gradle 7.4.2, 7.5.1 AGP 7.2.2.

I have tried different IDEs:

• AS Chipmunk 2021.2.1 Patch 2
• AS Dolphin 2021.3.1 RC 1
• AS Flamingo 2022.2.1 Canary 1
• IDEA Ultimate 2022.2.1

I have also tried different OSs - Ubuntu and macOS.

I have attached a reproducer project - Reproducer.zip.

If you apply the original androidx compose libraries to the Android source set (androidMain), the IDE issue is gone.

try specifying these two properties in gradle properties of the project & subprojects

kotlin.mpp.enableGranularSourceSetsMetadata=true
kotlin.mpp.hierarchicalStructureSupport=true

@wakaztahir Isn't HMPP is enabled by default since 1.6.20? https://kotlinlang.org/docs/multiplatform-hierarchy.html

[wakaztahir]

yeah , I thought you might have them false , since I was having issues and found it was false

It seems reproducible with AGP 7.2.2, but isn't reproducible with AGP 7.3.0 or AGP 7.1.3.

AGP 7.3.0 is supported by IDEA 2022.3 EAP (223.4884.69) and Android Studio Dolphin 2021.3.1

I couldn't use AGP 7.1.3 with Kotlin 1.7.10. For example Android lint fails with error messages like:

Meantime, there seems to be a workaround with AGP 7.2.2. Just add Jetpack Compose original dependencies in pure Android modules and androidMain KMP source sets.

implementation("androidx.compose.foundation:foundation:1.2.1")
implementation("androidx.compose.material:material:1.2.1")
