Implicit task dependency when using Gradle 8 + KMP custom cinterop #2977
Description
Describe the bug
You can see the issue here: cashapp/redwood#823. We're trying to upgrade from Gradle 7.6 -> 8.x and see implicit task dependency issues:
- Gradle detected a problem with the following location: '/Users/runner/work/redwood/redwood/.gradle/kotlin/kotlinTransformedCInteropMetadataLibraries/app.cash.zipline-zipline-0.9.17-nativeMain-cinterop/app.cash.zipline_zipline-cinterop-quickjs-wkj8jQ.klib'.
Reason: Task ':redwood-treehouse:dokkaHtmlPartial' uses this output of task ':redwood-protocol-widget:transformIosMainCInteropDependenciesMetadataForIde' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
Possible solutions:
1. Declare task ':redwood-protocol-widget:transformIosMainCInteropDependenciesMetadataForIde' as an input of ':redwood-treehouse:dokkaHtmlPartial'.
2. Declare an explicit dependency on ':redwood-protocol-widget:transformIosMainCInteropDependenciesMetadataForIde' from ':redwood-treehouse:dokkaHtmlPartial' using Task#dependsOn.
3. Declare an explicit dependency on ':redwood-protocol-widget:transformIosMainCInteropDependenciesMetadataForIde' from ':redwood-treehouse:dokkaHtmlPartial' using Task#mustRunAfter.
To Reproduce
git clone https://github.com/cashapp/redwood.git -b renovate/gradle-8.x
cd redwood
./gradlew dokkaHtmlMultiModule
If we remove kotlin.mpp.enableCInteropCommonization=true from gradle.properties, dokkaHtmlMultiModule then builds successfully
