Could not find "org.jetbrains.kotlinx:atomicfu-cinterop-interop" when using coroutines 1.8.0-RC

[mvicsokolova]

The following error was reproduced in projects, that depended solely on kotlinx.coroutines 1.8.0-RC and did not have a direct dependency to atomicfu:

> Task :compileKotlinIosArm64 FAILED
e: Could not find "org.jetbrains.kotlinx:atomicfu-cinterop-interop" in [/.konan/klib,/.konan/kotlin-native-prebuilt-macos-aarch64-1.9.21/klib/common, /.konan/kotlin-native-prebuilt-macos-aarch64-1.9.21/klib/platform/ios_arm64]

The reason: kotlinx.coroutines were built with the latest version of atomicfu-gradle-plugin that does not provide a transitive dependency to atomicfu in case of enabled Native IR transformation. Though it is still required, because coroutines use declarations from kotlinx.atomicfu.locks module.

That is a problem on kotlinx.atomicfu side, it should always add the implementation atomicfu dependency for native targets.

The WA is adding atomicfu dependency manually:

val nativeMain by creating {
  dependencies {
    implementation("org.jetbrains.kotlinx:atomicfu:0.23.1")
  }
}

Also, see: Kotlin/kotlinx.coroutines#3968

Regression analysis:

The root cause: the only test that covered this scenario was smokeTest project in kotlinx-coroutines integration-testing. It emulates a user project that only depends on the locally published current coroutines. There were no native targets declared in the project, hence the native coroutine klib was not used and the compilation completed successfully.

Preventive steps taken: native targets were added to smokeTest in coroutines, also the user-project test was added to kotlinx-atomicfu to check the build of user projects against the library that uses atomicfu.
