Hi! I was just updating to Jetbrains Compose 1.12 and get this:

java.lang.NoClassDefFoundError: androidx/compose/ui/platform/CompositionLocals_commonStubsKt
	at _COROUTINE._BOUNDARY._(CoroutineDebugging.kt:42)
	at androidx.compose.ui.test.SkikoComposeUiTest$runTest$1.invokeSuspend(ComposeUiTest.skiko.kt:275)
	at kotlinx.coroutines.test.TestBuildersKt__TestBuildersKt$runTest$2$1$1.invokeSuspend(TestBuilders.kt:317)
Caused by: java.lang.NoClassDefFoundError: androidx/compose/ui/platform/CompositionLocals_commonStubsKt

I already aligned all my org.jetbrains.compose.* dependencies according to github.com/JetBrains/compose-multiplatform/…/v1.12.0's "Libraries" section and the gradle dependencies output also shows no sign of older (AndroidX) Compose versions than 1.12. What else could I do to debug / fix this issue?

_commonStubsKt

It seems like your build includes non-android google's stubs instead of JetBrains' Compose Multiplatform libraries.

What's your gradle dependencies shows exactly?

Hi @Ivan Matkov, I pasted the desktop* specfic configurations here: <https://pastebin.ca/4knCLUzU8A> Thanks for your support!

Thanks.
I do not see a reason here 🤔
My assumption was that it somehow has a dependency to androidx.compose.ui instead of org.jetbrains.compose.ui because CompositionLocals_commonStubsKt clearly points to CompositionLocals.commonStubs.kt file in Google repo that contains no implementation and used as "stub" for non android targets.

Could you please file an issue to youtrack.jetbrains.com/newIssue?project=CMP with reproduction, so the team can a look at it in details?

Ok, I think the culprit was that I previously copied the Flow.flowWithLifecycle implementation over from AndroidX to Desktop because it was not available back in the day for that platform. By removing this and using the AndroidX-supplied variant for Desktop the error is gone.

Thanks for your support! You pointed me into the right direction.
