Question

Hi everyone I understand that if I develop a KMM Compose library Android developers would have to add org jetbrains compose plugin in their app module to prevent duplicate class errors On the other hand in my android specific libraries that also use compose this plugin is not needed when a KMM Compose library is added as a dependency That s really confusing to me My actual question is Is there any other way that Android developers can apply in their projects to prevent duplicate class errors without using org jetbrains compose plugin

Is there a planned solution for this Being able to share libraries seamlessly between Android and Jetbrains is an important piece for the compose ecosystem to grow in a multiplatform way

I thought that Google s plugin did all the replacing I was looking at the plugin code and saw a bunch of replacement stuff

Halil Ozercan · Answer

Not exactly Google s but as I said Jetbrains compose plugin resolves this issue Understandably I don t think many Android developers want to include this plugin in their app just because they are using an KMP library The code I sent is directly from that plugin and the only necessary part for an Android app to use an KMP Compose library

This is a known issue for us and we together work to make life easier here I expect some news in reasonable timeframe

Halil Ozercan · Answer

Developing a KMP Compose library was fun until I realized that Android apps cannot depend on KMP compose libraries without applying `org jetbrains compose` plugin This was unfortunate because I didn t feel right telling developers that they need to apply Desktop Compose plugin for their pure Android app just to use a library Luckily this turns out to be just a dependency issue and dependencies are easily replaced in gradle before they are resolved Adding the following configuration to Android App s `build gradle` enables the use of KMP Compose dependencies ```configurations all resolutionStrategy eachDependency DependencyResolveDetails details gt if details requested group contains org jetbrains compose def groupName = details requested group replace org jetbrains compose androidx compose details useTarget group groupName name details requested name version details requested version ```

You can also publish your library removing all Compose Desktop transitive dependencies

burnoo · Answer

Maybe `org jetbrains compose` plugin could produce additional ` jetpack` artifact with replaced dependencies Projects that do not use Compose Multiplatform could use the Jetpack version of the library and would not have to replace dependencies at build time I did something similar <https github com burnoo cokoin|in my library> but semi manually

Alexander Kurasov[JB] · Answer

We are considering one approach here Probably there will be an experimental CMPP build soon that will reference Jetpack Compose for android platform and thus there will be no duplicate class issue This is truly experimental approach but I hope it will work

Alexander Kurasov[JB] · Answer

< Halil Ozercan> We have published experimental build that is compatible with Jetpack 0 0 0 master build423 It uses 1 1 0 alpha06 Jetpack artifacts for android target IMO it should solve this problem If you build your MPP library based on it it will be possible to use it in Android projects that uses Jetpack Compose Simple smoke test is to take any android project and add there simultaneously ```implementation androidx compose ui ui $compose version ``` and ```implementation org jetbrains compose ui ui $mpp compose version ``` versions are ```buildscript ext compose version = 1 1 0 alpha06 mpp compose version = 0 0 0 master build423 ``` The build is published in ```maven url ``` Let me know if it works or you have some issues with it

< burnoo> I see you also might be interested in information above

burnoo · Answer

Works exactly as expected thanks Both `jvm` and `android` targets works with Jetpack Compose Tested <https github com burnoo cokoin commit b2ca8945c1f57f6b87b358635e3570bce1e9d1ec|here>
