ModuleDestinations$Includes is defined multiple times in Multi-Module project

[Velord]

Btw I use "2.1.0-beta02".

com.ramcosta.composedestinations.generated.ModuleDestinations$Includes is defined multiple times: ProjectPath\ui\feature-settings\build\.transforms\2d944e4462518b939e46cbbcdcc610c7\transformed\bundleLibRuntimeToDirDebug\com\ramcosta\composedestinations\generated\ModuleDestinations$Includes.dex, ProjectPath\ui\feature-bottomnavigation\build\.transforms\12913506a8e8a347cda5275057060a14\transformed\bundleLibRuntimeToDirDebug\com\ramcosta\composedestinations\generated\ModuleDestinations$Includes.dex

I have app module which defines all graphs.

DestinationsNavHost(
    navGraph = NavGraphs.mainNavGraph,
    dependenciesContainerBuilder = {
        dependency(CoreFeatureNavigator(navController = navController))
   }
)

private const val MAIN_GRAPH = "main_nav_graph"
@NavHostGraph(
    defaultTransitions = DefaultTransitions::class,
    route = MAIN_GRAPH,
    visibility = CodeGenVisibility.INTERNAL
)
annotation class MainGraph {
    @ExternalDestination<BottomNavigationDestinationsScreenDestination>(start = true)
    companion object Includes
}

class CoreFeatureNavigator(
    private val navController: NavController
) : BottomNavigator {

    override fun getRoute(route: BottomNavigationDestination): DestinationSpec = when(route) {
        BottomNavigationDestination.Camera -> CameraScreenDestination
        BottomNavigationDestination.Demo -> DemoScreenDestination
        BottomNavigationDestination.Settings -> SettingsScreenDestination
    }

    override fun getGraph(): NavHostGraphSpec = NavGraphs.bottomNavigationGraph
}

private const val BOTTOM_NAVIGATION_GRAPH = "bottom_navigation_graph"
@NavHostGraph(route = BOTTOM_NAVIGATION_GRAPH)
annotation class BottomNavigationGraph {
    @ExternalDestination<SettingsScreenDestination>
    companion object FF // trying to rename -> does not help
}

@Composable
private fun TestStackScreen() {
...

@Destination<BottomNavigationGraph>(start = true)
@Composable
fun CameraScreen() {
...

@Destination<BottomNavigationGraph>()
@Composable
fun DemoScreen() {
...

Also bottomnavigation module which defines destination:

interface BottomNavigator {
    fun getRoute(route: BottomNavigationDestination): DestinationSpec
    fun getGraph(): NavHostGraphSpec
}

enum class BottomNavigationDestination {
    Camera,
    Demo,
    Settings;
}

@Destination<ExternalModuleGraph>()
@Composable
fun BottomNavigationDestinationsScreen(
    navigator: BottomNavigator
) {

I am trying to split destinations that belong to bottom navigation graph to different modules. First step is to move 'settings' destination to different module. Exactly at this step error occurs.
My settingsmodule has:

@Destination<ExternalModuleGraph>
@Composable
fun SettingsScreen() {
...

1. I was trying to rename companion object in BottomNavigationGraph.
2. I added arg("compose-destinations.moduleName", "settings") and arg("compose-destinations.moduleName", "bottom"). Error occurs in that case: [ksp] com.ramcosta.composedestinations.codegen.commons.IllegalDestinationsSetup: Check com.google.devtools.ksp.symbol.NonExistLocation@3d60ec1b for unresolved symbols.
3. Also I was trying to add arg("compose-destinations.codeGenPackageName", xxxxx.settings") and arg("compose-destinations.codeGenPackageName", "xxxxx.bottom"). Error occurs in that case: [ksp] com.ramcosta.composedestinations.codegen.commons.IllegalDestinationsSetup: Check com.google.devtools.ksp.symbol.NonExistLocation@41e0988e for unresolved symbols.

Hi! 👋

You want to go with your try 2:

• add the module name on gradle ksp config, such that ModuleDestinations won't be generated always with same package name and name.
• After doing that, make sure your other imports are correct. It's likely that destinations will be generated in a different package name after that, so you'll need to update those imports.

After that try again and let me know!

I added to all modules arg("compose-destinations.moduleName", "moduleX") where X is unique name for certain module. After that I received an error on build: e: file:///D:/Android%20Project/ComposeScreenExample/app/build/generated/ksp/developDebug/kotlin/com/ramcosta/composedestinations/generated/moduleapp/navargs/ArgsToSavedStateHandle.kt:6:74 Unresolved reference: navargs
