Using the new multi-platform gradle plugin to build a MP module(android/JS/iOS)
with grade 4.7 with metadata enabled. When I try to define cinterop for an
objC/swift dependency (firebase-firestorm-ios) and have 'kotlinx-coroutines-core-native' as a dependency I get an error (only when defining cinterop):


* What went wrong:
Could not resolve all files for configuration 'common alliOSFirestoreCInterop'.

Could not resolve org.jetbrains.kotlinxkotlinx coroutines core native1.0.1.

Required by:
project :common-all
> Unable to find a matching configuration of org.jetbrains.kotlinxkotlinx coroutines core native1.0.1:

....

The build file can be found here: https://github.com/RubyLichtenstein/Kotlin-Multiplatform-Firebase/blob/ios/common-all/build.gradle
Any ideas? I suppose since I was targeting 'iosArm64' that the correct configuration should have been 'debugIos_arm64Link'
but there is a mismatch due to 'Required org.gradle.usage 'java-api' and found incompatible value 'kotlin-api''.

It's a known problem with a cinterop in 1.3.0 and it is fixed in 1.3.10. As a workaround you can manually specify the needed attributes, just add this code snippet in your build script:

kotlin.targets.matching { it.platformType.name == 'native' }.all {
    compilations.all { 
        cinterops.all {
            configurations[dependencyConfigurationName].attributes.attribute(
                Usage.USAGE_ATTRIBUTE, 
                objects.named(Usage, 'kotlin-api')
            )
        }
    }
}

Thanks. I forgot to update. It is also already fixed in more recent dev releases of the plugin.
