Need help with Kotlin Multiplatform iOS build issue

I’m running into a problem when building our KMP project, specifically with the task

:composeApp:compileKotlinIosSimulatorArm64.

Instead of generating a .klib file at:

compose App/build/classes/kotlin/ios Simulator Arm64/main/lib/compose App

the build consistently creates a directory named composeApp/ (inside it there’s a default/ folder and other files). As a result, the build fails with:

java.io.FileNotFoundException: ...compose App (Is a directory)

- kotlin: 2.1.21, cmp: 1.7.3

Has anyone seen this behavior where a .klib is expected but a directory is created instead? Any ideas what might be causing this or how to debug it further?

Appreciate any pointers 🙏

directory is expected for this task. What is your compilation problem exactly? Could you share a Gradle build scan? Or full stacktrace?

when i'm trying to launch ios application, i'm getting this error:

❌ /.../composeApp/build/classes/kotlin/iosSimulatorArm64/main/klib/composeApp (Is a directory)
❌ /.../composeApp/build/classes/kotlin/iosSimulatorArm64/main/klib/composeApp (Is a directory)

Could you share the full stacktrace?

[tapchicoma]

could you add --stacktrace to Gradle invocation and share the produced stacktrace?

[tapchicoma]

Or parametrize through `gradle.properties`:

org.gradle.logging.stacktrace=always

I suppose you need to update moko-resources to 0.24.5 release: https://github.com/icerockdev/moko-resources/releases/tag/release%2F0.24.5

I tried it, but I updated the dependency, not the plugin itself. This fixed the problem, thanks!
