Question

I have updated Kotlin version to 1 7 0 in my library and when I publish it everything works fine However using the library from another multi platform project I can t access the common source set If I downgrade to Kotlin 1 6 10 and publish it again with a different version I can access the common source set from the other project Is there something has changed in 1 7 0 that I m not aware of Or is it somehow not related to the Kotlin version More info in the thread

Trevor Stone · Answer

I believe 1 7 x libraries are only consumable by applications also on 1 7 x

Ali Albaali · Answer

< Trevor Stone> I m using Kotlin 1 7 0 in both projects

Trevor Stone · Answer

Potentially <https kotlinlang org docs multiplatform hierarchy html> There was a change in default behavior between 1 6 10 and 1 6 20

Ali Albaali · Answer

Okay I assume it is enabled by default for projects and libraries that are using version 1 7 0 correct When adding this flag to the library ```kotlin mpp enableCompatibilityMetadataVariant=true``` Gradle sync works fine However when I publish to mavenLocal i get this error ``` gt Could not resolve all files for configuration kamel core metadataCompileClasspath gt Could not resolve org jetbrains compose ui ui 1 2 0 alpha01 dev753 ``` When adding this flag to the project ```kotlin mpp hierarchicalStructureSupport=false``` Gradle sync fails with this error ```kotlin UninitializedPropertyAccessException lateinit property targets has not been initialized at org jetbrains kotlin gradle dsl KotlinMultiplatformExtension getTargets KotlinMultiplatformExtension kt 25 ``` What am I missing

Mitchell Syer · Answer

I looked at Kamel and I think its because your only publishing a jvm sourceset with no other sourceSets like android

Mitchell Syer · Answer

You can take a look at one of my forks for an example of setting up a compose library for Jvm and Android <https github com Syer10 compose material dialogs>

Ali Albaali · Answer

< Mitchell Syer> If you see the images I have attached they include android and desktop source sets Meaning I can use the library code from the android and desktop source sets including the modules The problem is with the `commonMain` source set I can t access the library from there with Kotlin version 1 7 0

Trevor Stone · Answer

Can you post your gradle properties file

Ali Albaali · Answer

For library ```kotlin code style=official android useAndroidX=true kotlin mpp stability nowarn=true kotlin mpp enableCompatibilityMetadataVariant=true``` For project ```kotlin code style=official android useAndroidX=true kotlin mpp enableGranularSourceSetsMetadata=true kotlin native enableDependencyPropagation=false kotlin mpp stability nowarn=true org gradle jvmargs= Xmx4096m kotlin mpp hierarchicalStructureSupport=false```

Mitchell Syer · Answer

< Ali Albaali> I meant for Kamel core I think because it only uses jvm that it cant be used for projects that use both jvm and android because it doesnt provide the required metadata

Mitchell Syer · Answer

It probably worked fine for projects without HMPP because it was much simpler HMPP is smarter more advanced

Trevor Stone · Answer

It looks like the library is just android and desktop though right so just supporting jvm would be fine

Trevor Stone · Answer

to the initial question because I think I focused on the wrong thing I have updated Kotlin version to 1 7 0 in my library and when I publish it everything works fine However using the library from another multi platform project I can t access the common source set

Trevor Stone · Answer

It syncs correctly but then when you are trying to consume it code isn t accessible

Ali Albaali · Answer

< Mitchell Syer> I understand I should ve mentioned that using the kamel core module works fine I can access everything from it e g Resource KamelConfig etc The problem is with kamel image module I can t access lazyPainterResource or KamelImage composables from commonMain source set

Ali Albaali · Answer

< Trevor Stone> Yes the library supports only android and desktop If you check this you can see everything is uploaded correctly

Mitchell Syer · Answer

I was noticing that with my project as well it uses Kamel and it builds fine but the ide cant find anything in Kamel

Ali Albaali · Answer

< Trevor Stone> Only the code from `kamel image` commonMain source set isn t accessible The code from `kamel image` module with androidMain and desktopMain is accessible and working fine

Trevor Stone · Answer

in your project consuming the library how are you defining the dependencies

Ali Albaali · Answer

```val commonMain by getting dependencies api compose runtime api compose foundation api compose material api compose material3 api compose materialIconsExtended implementation project data api org jetbrains kotlinx kotlinx datetime 0 3 3 api com alialbaali kamel kamel image 0 4 21 api com halilibo compose richtext richtext commonmark 0 10 0 ```

Trevor Stone · Answer

why is `kotlin mpp hierarchicalStructureSupport=false` in your project

Ali Albaali · Answer

I tried to disable it to see if it works It wasn t there before

Ali Albaali · Answer

You can try to create new project by using the default template add the library and you ll see the problem is there

andylamax · Answer

I am also having this very same problem I have battled with it all night to no avail

Trevor Stone · Answer

I tired playing with it more last night and was able to build the project with code in the common source set but the IDE wouldn t resolve correctly and showed errors

Ali Albaali · Answer

< Trevor Stone> does it show the `kamel image` commonMain package in the External libraries view

Ali Albaali · Answer

It does build without any errors so I think the problem is with Kotlin IDE plugin it is not identifying the commonMain source set
