After upgrading from 1.9.23 to 2.0.0-RC1, I get the following error.

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':shared:linkPodDebugFrameworkIosArm64'.
Caused by: java.lang.IllegalStateException: Following dependencies exported in the podDebugFramework binary are not specified as API-dependencies of a corresponding source set:

Please add them in the API-dependencies and rerun the build.

All of the mentioned dependencies are defined as api in commonMain and the project builds on 1.9.23. Copying the dependency to iosMain does not help either.

Hi! I noticed the same issue while adding support for SKIE for Kotlin 2.0.0.

It’s an issue with the order of the dependency and export declaration, here is a reproducer:

plugins {
    kotlin("multiplatform") version "2.0.0-Beta5"
}

group = "co.touchlab"
version = "1.0-SNAPSHOT"

repositories {
    mavenLocal()
    mavenCentral()
}

kotlin {
    ios()
    iosSimulatorArm64()
    iosX64()

//    Uncomment and it will work
//    val iosMain by sourceSets.getting {
//        dependencies {
//            api("co.touchlab:kermit:2.0.0")
//        }
//    }

    applyDefaultHierarchyTemplate()

    targets.withType<org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget> {
        binaries {
            framework {
                isStatic = true
                baseName = "SKIE-test"
                freeCompilerArgs = freeCompilerArgs + listOf("-Xbinary=bundleId=Kotlin")
                export("co.touchlab:kermit:2.0.0")
            }
        }
    }
    
//    Uncomment and it will not work
//    val iosMain by sourceSets.getting {
//        dependencies {
//            api("co.touchlab:kermit:2.0.0")
//        }
//    }
}

The crash itself originates in KotlinNativeLink object in the validatedExportedLibraries function. The function compares exported libraries with those that are declared as api dependencies. The issue is that the list of API dependencies is computed in the object constructor which happens when you declare the binaries.framework. Because the exported library is not declared yet (the dependencies block is after the framework declaration block), the property apiFiles does not contain it. This was the case for a very long time. What has changed in the 2.0.0 is that the KotlinNativeLink is now instantiated eagerly when you declare the binaries.framework. Or more precisely the Framework object itself is now instantiated eagerly.

[Filip Dolník]

A secondary effect of this issue is also that Gradle plugins cannot add dependencies that they want to export (which is the actual issue I run into with SKIE).

[Timofey Solonin]

Hi folks. Is my understanding correct that you use freeCompilerArgs in the framework block? Could you please see if using the following instead of the freeCompilerArgs helps:

linkTaskProvider.configure {
    toolOptions {
        freeCompilerArgs.add("-Xbinary=bundleId=Kotlin")
    }
}

If this doesn't help, could you please provide a reproduction?

[Filip Dolník]

Yeah, replacing the freeCompilerArgs = freeCompilerArgs + listOf("-Xbinary=bundleId=Kotlin") fixes the issue. Touching the freeCompilerArgs is what is causing the KotlinNativeLink to get created in my case at least.

[Timofey Solonin]

Here is the bug

[Filip Dolník]

To clarify the original message. As it turned out I tested the difference between 1.9.23 and 2.0.0 with a slightly different Gradle configs (missing the key freeCompilerArgs line 😄) so that explains why I haven’t seen the KotlinNativeLink being created eagerly.

The issue indeed seems to be that the original apiFiles FileCollection was “live” and now it’s not.
