# multiplatform

[Javier]

I have a jvm module which is implementing a kotlin multiplatform module that only have jvmMain target. The build is working perfectly and all tests pass. But if I go to some file inside the jvm module, I see that all referecences from jvm multiplatform module are unresolved, anyone know why this is happening?

It is a known bug if you have also Android target in your project

Sharing code between JVM and Android

[Javier]

Yeap, we have an app module which implements this multiplatform module. It is working there fine indeed

[Mustafa Ozhan]

yes exactly, IDE will give error but if you run your task with command line you will see that it will work

[Javier]

But this is not going to be fixed until 1.5 (march)? The development in this state is impossible. The only solution is to migrate all jvm modules to multiplatform modules with only jvm targets?

[Mustafa Ozhan]

Well I am not right person to answer this, probably someone from JB can answer this, it is slowing down my progress also but not impossible

[Javier]

implementing multiplatform in another multiplatform (only with jvm targets) have this problem too?

[Javier]

Is there any youtrack issue where this is redacted?

[Javier]

Changing the jvm module that implements the multiplatform module to android module is working fine

[mbonnin]

I filed that some time ago: https://issuetracker.google.com/issues/165921901

[mbonnin]

Would be nice to have an issue on youtrack as well

[mbonnin]

To workaround, I set a custom gradle property in my ~/.gradle and use that to remove Android portions

[russhwolf]

For youtrack issues, https://youtrack.jetbrains.com/issue/KT-29082 is related. I thought there was a better one but I'm having trouble finding it off-hand, so maybe it's worth logging something. I think it probably belongs more on the JetBrains side than the Google side but 🤷

[Javier]

yep, with android modules it is working perfectly, so it is more related to JetBrains JVM kotlin plugin

@mbonnin how exactly do you proceed with disabling android module? I tried:
• commenting out include(“:android”) app module from settings
• commenting out id(“com.android.library”) in common module plugins dsl
• commenting out androidMain and androidTest sources sets in sourceSets dsl
• commenting out android() in kotlin dsl in common module
• commenting out android block dsl in common module
• commenting out whole build.gradle.kts in android app module
Still, I can’t get my jvm module to recognize commonMain classes

[Javier]

I didn't disabled it. Converting JVM module to android module let intellij to recognize the common classes

[Javier]

i find no way to fix it with JVM

[mbonnin]

commenting out include(“:android”) app module from settings

That's what I would have done

Still, I can’t get my jvm module to recognize commonMain classes

That sucks. Can you upload a small reproducer somewhere? It might be another bug

this class has errors in IDE. switch branch to cannot_disable_android after cloning

[solidogen]

Ok I got it. Steps I performed are okay, but to work on JVM app module, I have to switch from Android Studio to IntelliJ, add when error pops, I need to apply an IDE suggestion - add dependency on common.commonMain.
Then classes get resolved correctly.

[Javier]

well the problem is “solved” if I just remove from settings.gradle.kts the jvm module or the android application module

[Javier]

[Javier]

I can’t have both at same time

[Javier]

I think AGP 7.0.0-alpha02 fix this problem (maybe 01 too, I haven’t tried). The problem is you need to use Android Studio Canary, should be great that Google adds a flag to allow using new version on old IDEs
