Instrumented test coverage fails with coroutines 1.10.0+

[Del-S]

Issue: Cannot run instrumented tests when enableAndroidTestCoverage is set to true while using coroutines 1.10.0+. I tried 1.9.0 and it works fine.

* What went wrong:
Execution failed for task ':codebase:domain:mergeExtDexDevDebugAndroidTest'.
> Could not resolve all files for configuration ':codebase:domain:devDebugAndroidTestRuntimeClasspath'.
   > Failed to transform kotlinx-coroutines-debug-1.10.1.jar (org.jetbrains.kotlinx:kotlinx-coroutines-debug:1.10.1) to match attributes {artifactType=android-dex, dexing-component-attributes=ComponentSpecificParameters(minSdkVersion=24, debuggable=true, enableCoreLibraryDesugaring=true, enableGlobalSynthetics=true, enableApiModeling=false, dependenciesClassesAreInstrumented=false, asmTransformComponent=null, useJacocoTransformInstrumentation=true, enableDesugaring=true, needsClasspath=false, useFullClasspath=false, componentIfUsingFullClasspath=null), org.gradle.category=library, org.gradle.dependency.bundling=external, org.gradle.jvm.environment=standard-jvm, org.gradle.jvm.version=8, org.gradle.libraryelements=jar, org.gradle.status=release, org.gradle.usage=java-runtime, org.jetbrains.kotlin.platform.type=jvm}.

So for now I just want to check coverage while writing tests but we might need to have coverage report combined for unit tests and instrumented tests. I will try to provide some example project during the weekend (I hope), but if anyone has an idea why this happens in the meantime I would appreciate help with this. Thanks.

Looks like your code coverage tool attempts to also check how well your tests cover the code in kotlinx.coroutines. It's worth a try to exclude kotlinx.coroutines code from your coverage check. I don't know how to do that, though; maybe you could ask on Stack Overflow or in Kotlin Slack. Or maybe Android or Jacoco teams could shed some light on this.

Thanks I will take a look at it tomorrow. But the weird thing is that only thing I did is to enable the coverage and I believe it uses embedded Jacoco from AGP or something like that. Also coverage for unit tests works fine. It also starts working if I downgrade coroutines library which I have no idea why. 🤔 But thanks anyway.

Hmm so now the same happens with Paparazzi tests:

So I just checked the jar files for kotlin-coroutines-debug and 1.9.0 has only one module-info.class inside

But 1.10.1 (same with 1.10.0) has two:

If that's the issue, it will be fixed in the next release by #4314

Ah great. Thanks. :)
