Error java.lang.RuntimeException: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

[adydecki]

Android application type

Android for .NET (net6.0-android, etc.)

Affected platform version

.NET 6.0.301

Description

When two packages Square.OkHttp3 and Xamarin.Kotlin.StdLib are added to the .net6-android application then compile time error (as shown in the repro steps) occurs during the application build.

Steps to Reproduce

1. create new Android application, i.e. dotnet new android -n AndroidApp
2. cd to /AndroidApp and add Xamarin.Kotlin.StdLib and Square.OkHttp3 packages, i.e. dotnet add package Xamarin.Kotlin.StdLib dotnet add package Square.OkHttp3
3. build the application dotnet build
4. the following compile time error shows up
   /usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/32.0.415/tools/Xamarin.Android.D8.targets(79,5): error : java.lang.RuntimeException: com.android.tools.r8.CompilationFailedException: Compilation failed to complete, origin: /Users/adrian/.nuget/packages/xamarin.kotlin.stdlib/1.6.21.1/buildTransitive/net6.0-android31.0/../../jar/org.jetbrains.kotlin.kotlin-stdlib-1.6.21.jar : kotlin/collections/ArraysUtilJVM.class [/Users/adrian/Dev/projects/github/net6-maui-test/AndroidApp/AndroidApp.csproj]

Above steps can be found in the repository https://github.com/adydecki/net6-maui-test/tree/main/AndroidApp

@jpobst do we own Square.OkHttp3?

The error is:

Caused by: com.android.tools.r8.internal.f: Type org.jetbrains.annotations.Unmodifiable is defined multiple times: C:\Users\jopepper\.nuget\packages\xamarin.jetbrains.annotations\23.0.0.4\buildTransitive\net6.0-android31.0\..\..\jar\org.jetbrains.annotations-23.0.0.jar:org/jetbrains/annotations/Unmodifiable.class, obj\Debug\net6.0-android\lp\5\jl\libs\DB43F1C10974DC83.jar:org/jetbrains/annotations/Unmodifiable.class

I think it's redistributing things it shouldn't be. Similar to some of the issues we had with AndroidX/GPS.

[jpobst]

Yes, we bind it out of the GPS repository.

These lines need to be updated to the latest Kotlin versions:
https://github.com/xamarin/GooglePlayServicesComponents/blob/main/config.json#L1951-L1974

The 1.5.31.2 version listed is missing the Condition part of the .targets, so it is adding the library inside the Square.OkHttp3 package.

<AndroidJavaLibrary Condition=" '$(AndroidApplication)' == 'true' " Include="$(MSBuildThisFileDirectory)..\..\jar\org.jetbrains.kotlin.kotlin-stdlib-1.6.21.jar" />

[adydecki]

Thank you for your answers. Is there a workaround to this issue?
Our application depends on the following packages and fails to build because some of the mentioned packages (Xamairn.AndroidX.Fragment) have a hard dependency to Kotlin ver>=1.6.10.

Xamarin.AndroidX.AppCompat ver="1.3.1.3"
Xamarin.AndroidX.ConstraintLayout ver="2.1.1.2"
Xamarin.AndroidX.CoordinatorLayout ver="1.1.0.10"
Xamarin.AndroidX.Fragment ver="1.4.1"
Xamarin.AndroidX.RecyclerView ver="1.2.1.6"
Xamarin.Kotlin.StdLib ver="1.6.10"
Square.OkHttp3 ver="4.9.2.3"

[jonathanpeppers]

@adydecki the workaround would be to delete the above DB43F....jar file from Square.OkHttp3.aar.

@jonathanpeppers Do we still need to do the workaround by far?

[jonathanpeppers]

No, this was fixed in #649.

You might update all NuGet packages and see if that is the problem.

[tuyen-vuduc]

@jonathanpeppers Can you advise which packages in particular?

[jonathanpeppers]

@moljac what versions of GPS packages would contain #649?

[tuyen-vuduc]

@jonathanpeppers After upgrading Square.OkHttp3 to the latest version, it seems to be ok. I will revert if I face any other issues.

[moljac]

@moljac what versions of GPS packages would contain #649?

There was tons of updates since 2022-07. Several times bumped all packages for various reasons.

Do you want me to go deeper into details?
