Anyone have luck with Compose Multiplatform and Koin Compiler with Annotations? It finds all my repos, Daos, online data sync manager, but @KoinViewModel doesn't do anything. It worked fine with KSP annotations.

Just my basic persistence viewmodel for basic app data doesn't load:

@KoinViewModel
class AppViewModel(
    private val persistenceRepository: PersistenceRepository,
    festivalRepository: FestivalRepository,
    private val syncFestivalDataUseCase: SyncFestivalDataUseCase
) : ViewModel() {

I have 5 other viewmodels that it doesn't even get to try loading before I get exceptions about not finding the definition of AppViewModel...

sounds like your ViewModels are not attached to your modules? 🤔

Are you using @ComponentScan ?

w: [Koin] Intercepting startKoin<com.jimtj.festivalapp.di.FestivalAppConfig>()
w: [Koin]   -> No modules to inject

can this be the issue? You need to have in your main app module this so it scans the stuff in the app module

@Module
@Configuration // so it can be discoverd by the @KoinApplication
@ComponentScan // so it can scan the current package
class AppModule

Then you also need your application:
@KoinApplication
class MyApplication

I noticed for my Android project, that startKoinMyApplication() (or koinConfigurationMyApplicaiton()) should also live in the same gradle module as where you defined the previous 2 so it can intercept it and inject the module into it. If I leave the MyApplication in a shared module, and then do koinConfigurationMyApplication() from my Android application module, it will not find anything to inject

[arnaud.giuliani]

@Module + @Configuration can be scanned through Gradle modules
