Kotlinx.coroutines: Compilation error on the androidTest configuration after updating to 1.3.6

[dmarin]

The compilation error occurs after updating to 1.3.6, and it gets fixed if I downgrade to 1.3.5.

Kotlin Version 1.3.72

The coroutines dependencies I am using are:

implementation platform("org.jetbrains.kotlinx:kotlinx-coroutines-bom:${Versions.COROUTINES_VERSION}")
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-play-services"

testImplementation "org.jetbrains.kotlinx:kotlinx-coroutines-test"
androidTestImplementation "org.jetbrains.kotlinx:kotlinx-coroutines-test"

Stacktrace:
```

• What went wrong:
  Execution failed for task ':app:mergeStagingDebugAndroidTestJavaResource'.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
More than one file was found with OS independent path 'win32-x86/attach_hotspot_windows.dll'

• Try:
  Run with --info or --debug option to get more log output. Run with --scan to get full insights.
• Exception is:
  org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:mergeStagingDebugAndroidTestJavaResource'.

I found 2 workarounds:

1. Exclude the duplicated files:

    packagingOptions {
        exclude "**/attach_hotspot_windows.dll"
        exclude "META-INF/licenses/**"
        exclude "META-INF/AL2.0"
        exclude "META-INF/LGPL2.1"
    }

1. Exclude the kotlinx-coroutines-debug dependency

resolutionStrategy {
  exclude group: "org.jetbrains.kotlinx", module: "kotlinx-coroutines-debug"
}

[caiodev]

Thanks @dmarin. Just by putting:

packagingOptions {
exclude 'META-INF/AL2.0'
exclude 'META-INF/LGPL2.1'
}

Already did the trick

[qwwdfsad]

Could you please provide a reference to a reproducing Android project? Unfortunately, I cannot reproduce this build failure on simple projects

[proto-mvp]

getting similar error on androidTest

_> More than one file was found with OS independent path 'META-INF/AL2.0'_

packagingOptions {
exclude 'META-INF/AL2.0'
exclude 'META-INF/LGPL2.1'
}

and
exclude group: "org.jetbrains.kotlinx", module: "kotlinx-coroutines-debug"

Above suggestions do help on the problem when compiling for AndroidTest.

In case of multi-module setup, the exclude of the dependency should be applied to all the modules.

Kotlin coroutines upgraded to 1.3.6
Kotlin Version 1.3.72.

[dmarin]

Could you please provide a reference to a reproducing Android project? Unfortunately, I cannot reproduce this build failure on simple projects

I can reproduce part of the problem on a brand new project created from AS.

Steps:

1. In AS -> File -> New -> New project. On my test I chose the empty activity template, but I guess it can be reproduced with any of them.
2. in the app/build.gradle add the following snippet.

    implementation platform("org.jetbrains.kotlinx:kotlinx-coroutines-bom:1.3.7")
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-play-services"
    testImplementation "org.jetbrains.kotlinx:kotlinx-coroutines-test"
    androidTestImplementation "org.jetbrains.kotlinx:kotlinx-coroutines-test"

1. Try to run the ExampleInstrumentedTest test and you will get the compilation error.
   More than one file was found with OS independent path 'META-INF/AL2.0'

Notes:
Changing the kotlin bom version to 1.3.5 "fixes" compilation. So this issue was introduced in 1.3.6
In my project setup the first error I was getting was different:
More than one file was found with OS independent path 'win32-x86/attach_hotspot_windows.dll'
So probably there are 2 different issues?

@qwwdfsad Is this enough? or should I publish the repo reproducing the issue somewhere?

[qwwdfsad]

That's enough, thanks!

Seems to be related to a newer version of bytebuddy.

[alishen-diconium]

This issue still persists in 1.3.7

[dikhawk]

This issue still persists in 1.3.8

[francescocervone]

Looks like just excluding kotlinx-coroutines-debug module solves the issue in 1.3.8.
No need to exclude anything with packagingOptions.

resolutionStrategy {
  exclude group: "org.jetbrains.kotlinx", module: "kotlinx-coroutines-debug"
}

[caiodev]

@francescocervone That's what i got when i tried your solution:

No signature of method: build_2bz6cqdgyzucl8y9x7vl21swb.android() is applicable for argument types: (build_2bz6cqdgyzucl8y9x7vl21swb$_run_closure1) values: [build_2bz6cqdgyzucl8y9x7vl21swb$_run_closure1@18b6ad15]

The only thing that's working for me is:

packagingOptions {
exclude 'META-INF/AL2.0'
exclude 'META-INF/LGPL2.1'
}

[DDihanov]

Same problem. I get this not only on the androidTest config. Seems to work with

packagingOptions {
        exclude "**/attach_hotspot_windows.dll"
        exclude "META-INF/licenses/**"
        exclude "META-INF/AL2.0"
        exclude "META-INF/LGPL2.1"
    }

Any idea how long we gotta keep this around? Until the next coroutines version or?

[brescia123]

@francescocervone Thanks Ciccio!

[joerogers]

I've tracked the problem to be a conflict between the kotlinx-coroutines-debug package and mockito and how they include the ByteBuddy library.

Mockito includes ByteBuddy as a dependency, however the coroutines-debug imbeds ByteBuddy directly. Seems the best solution is coroutines-debug switches to a dependency model or does something to ensure the embedded version will not conflict with other libraries.

While mockito is the dependency that I hit, it is possible other libraries that depend ByteBuddy could generate this conflict.

I'm working around the problem by excluding the debug library which is a drag along dependency that I am not using.

androidTestImplementation("org.jetbrains.kotlinx:kotlinx-coroutines-test:$coroutines_version") {
        // conflicts with mockito due to direct inclusion of byte buddy
        exclude group: "org.jetbrains.kotlinx", module: "kotlinx-coroutines-debug"
    }

[DeuceTheCoder]

This issue still persists in 1.3.9

[dkhalanskyjb]

Using byte-buddy as a dependency instead of including it has other problems and wouldn't even solve this particular issue completely, so for now we've documented the workaround (the instructions have some details for those interested).

Also, a feature request for the Android build tools that, if implemented, would fix this: https://issuetracker.google.com/issues/170131605

    }

I updated all the test dependencies and androidTest dependencies and then added this snippet to my build.gradle (app). The packagingOptions never worked for me. Kotlin version: 1.4.21

[ZakTaccardi]

On Kotlin 1.4.30 and started observing this issue after upgrading to byte buddy 1.10.20.

Task that had this issue:

:lib:mergeDebugAndroidTestJavaResource

Fix was:

pickFirst("win32-x86/attach_hotspot_windows.dll")
pickFirst("win32-x86-64/attach_hotspot_windows.dll")
pickFirst("META-INF/licenses/ASM")

I prefer to skip all DLLs. Android does not support it anyway:

exclude("win32-x86/attach_hotspot_windows.dll")
exclude("win32-x86-64/attach_hotspot_windows.dll")

This issue still persists in 1.4.21

It's indeed is here, but unfortunately, there is nothing we can do about it.

We've added a section about it to readme a few releases ago.

I'm working on a Udacity/Kotlin/Android testing course UD940, lesson 11, and I am running into this error. The original is at Udacity's Github and I recommend you look at my code at this commit. I'm continuing to work on the course because of, and not despite this error; I think its a better example of what I may encounter in the wild than a nice, neat, well, planned lesson.
