Gradle sync fails after upgrading from 0.23.0 to 0.24.x

[vojta-horanek]

Our project fails to be synced (specifically the KMP module) after updating moko-resources to 0.24.3 from 0.23.0. As I've tested, the same happens when using any of the other 0.24.x versions. The build (Android and iOS) is working fine, however android studio fails to sync and thus indexing is not working correctly. What is strange is that if XCode runs the copyResourcesKMMSharedDomainDebugXCFrameworkToApp task, it completes successfully and resources are indeed copied to the iOS application.

The following issue is displayed when trying to sync:

Unable to build Kotlin project configuration
Failed building KotlinMPPGradleModel

org.gradle.api.internal.tasks.DefaultTaskContainer$TaskCreationException: Could not create task ':shared:copyResourcesKMMSharedDomainXCFrameworkToApp'.

...

Caused by: java.lang.ClassCastException: class org.gradle.api.DefaultTask_Decorated cannot be cast to class org.jetbrains.kotlin.gradle.plugin.mpp.apple.XCFrameworkTask (org.gradle.api.DefaultTask_Decorated is in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader @277c0f21; org.jetbrains.kotlin.gradle.plugin.mpp.apple.XCFrameworkTask is in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader$InstrumentingVisitableURLClassLoader @5fb60b55)

The name KMMSharedDomain comes from using configureCopyXCFrameworkResources("KMMSharedDomain") in the configuration.

I've experimented a bit and found out that when I don't use configureCopyXCFrameworkResources in the configuration, the sync actually completes just fine -> obvious since the task does not get registered 😄

I suspect the cast in SetupAppleUtils:registerCopyXCFrameworkResourcesToAppTask is the cause of the issue.

This is a screenshot from the debugger evaluating this.project.tasks.getByName("assemble$xcFrameworkName") right before the sync crashes.

Thanks in advance.

looks like you use configureCopyXCFrameworkResources when should not use it.
XCFrameworkTask should be created by kotlin gradle plugin when you configure xcframework.

can you show your build.gradle?

[vojta-horanek]

This is the build.gradle of our KMP module.

plugins {
    alias(libs.plugins.XXX.kmm.library)
    alias(libs.plugins.skie)
}

android {
    namespace = "xxxxxxxx"
    sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")

    buildFeatures {
        buildConfig = true
    }
}

multiplatformResources {
    resourcesPackage.set("xxxxxxx")
    configureCopyXCFrameworkResources("KMMSharedDomain")
}

sqldelight {
    databases {
        create("Database") {
            packageName.set("xxxx")
            verifyMigrations.set(true)
        }
    }
}

@vojta-horanek hi. in your build gradle i not see usage of XCFramework and also not see framework configuration at all.
can you show what do your XXX.kmm.library plugin?

configureCopyXCFrameworkResources should be used only with XCFramework kotlin api

I get the same issue and I already have XCFramework and configureCopyXCFrameworkResources in the same file. The difference I've and maybe that has something to do with my issue is that my resource is in another sub-module and XCFRamework I'm creating in umbrella module. So my configureResources method is in Umbrella.

Not sure if multi-module setup is the cause of the issue.

Let me know if I should do something differently in that case @Alex009

Here is the repro even with one module.
