Add cinterop stubs to custom source set

Native
1

I have a commonNativeMain source set and stubs generated from an Objective-C framework for many Apple targets. Of course the stubs have exactly the same APIs so I’d like to write once in nativeCommonMain and then compile for each target platform, so i went for:

val nativeCommonMain by creating {
    dependsOn(commonMain)
}

val iosArm64Main by getting {
    dependsOn(nativeCommonMain)
}
val iosX64Main by getting {
    dependsOn(nativeCommonMain)
}
val macosX64Main by getting {
    dependsOn(nativeCommonMain)
}

Now, while this solution compiles just fine, the code completion of IntelliJ IDEA does not know nothing about the stubs when inside commonNativeMain, which is very unpleasant!

Is there a solution to this problem?

I finally came up with a solution! I created a Gradle Sync task that copies the files from one source set to the others so that you have to write it only once.

Here’s my implementation, keep in mind that this task copies the entire main KotlinSorceSet to the others!

While I might belive that this is the best solution currently I don’t think this should be solved like this in the long run. Kotlin should have an option to pass on the stubs to different source sets. Maybe you should create a youtrack issue for this.

Looks like there is already, and it’s not new, almost a year!
