[Bug] @KoinApplication cannot set up modules directly with new compiler-plugin

[hmy65]

I tried a lot, org.koin.core.annotation.KoinViewModel cannot be scanned.

koin = "4.2.0"
koin-plugin = "0.4.1"

@Module(
    includes = [
        DataStoreModule::class,
        PermissionModule::class
    ]
)
@ComponentScan("my app package name")
class AppModule

@KoinApplication(modules = [AppModule::class])
class MyApp

startKoin<MyApp>()

@KoinViewModel
class AppViewModel(
    private val dataStoreRepository: DataStoreRepository
) :: ViewModel(){}

[Koin] Missing definition: ***.AppViewModel
  resolved by: koinViewModel<AppViewModel>()
  No matching definition found in any declared module.
  Check your declaration with Annotation or DSL.

I could make it run here: https://github.com/InsertKoinIO/playground-apps/tree/main/app-annotations and in otehr examples.
Can you detail more how do you do?

Thanks. @arnaudgiuliani
You provided its android only project. In my case, its compose multiplatform project.
But anyway, I found the core issue.

I use your sample way, it works.
https://github.com/InsertKoinIO/playground-apps/blob/main/app-annotations/app/src/main/kotlin/org/koin/sample/app/di/AppModule.kt

@Module(
    includes = [
        DataStoreModule::class,
        PermissionModule::class
    ]
)
@Configuration
@ComponentScan("my app package name")
class AppModule

@KoinApplication
class MyApp

Your way only cause slight IDE issue "class AppModule // <--- Grayed out as "Unused" by IDE"
related: #2362

But my way, which also should work by definition, failed

@Module(
    includes = [
        DataStoreModule::class,
        PermissionModule::class
    ]
)
@ComponentScan("my app package name")
class AppModule

@KoinApplication(modules = [AppModule::class])
class MyApp

Is this meant to be like this by design? Only @Configuration works.
But seems like @KoinApplication should be able set up modules.

@Target(AnnotationTarget.CLASS)
public annotation class KoinApplication(val configurations: Array<String> = [], val modules : Array<KClass<*>> = [Unit::class])

Ideally, I wanna use this way if it can work.

@KoinApplication(
    modules = [
        DataStoreModule::class,
        PermissionModule::class
    ]
)
@ComponentScan("my app package name")
class MyApp

Are you using either io.insert-koin:koin-core-viewmodel or io.insert-koin:koin-compose-viewmodel in this module?

I had similar error message before, and in my case the compiler wasn't generating code for KoinViewModel annotation whene these dependencies were missing
