我花了一些时间来解决我的错误，但没有任何积极的结果，所以我也许有人可以提供帮助。我的项目中有 3 个模块：app (android)、data、domain - 都是纯 kotlin。所有 DI 都在 app 模块中。

应用组件和应用模块：

@Singleton
@Component(modules = arrayOf(ApplicationModule::class,
        NavigatorModule::class,
        RepositoryModule::class,
        FirebaseModule::class,
        SchedulerModule::class,
        UseCaseModule::class))
interface ApplicationComponent {
    fun injectApplication(application: Application)

    fun loginSubComponent() : LoginSubComponent
}

@Module
class ApplicationModule(private val application: Application) {

    @Provides
    @Singleton
    fun provideApplication() = application
}

@Module
class UseCaseModule {

    @Provides
    @Singleton
    fun provideLoginAccountUseCase(scheduler: ComposeScheduler, repository: AccountRepository) = LoginAccountUseCase(scheduler, repository)

    @Provides
    @Singleton
    fun provideLoginAnonymousUseCase(scheduler: ComposeScheduler, repository: AccountRepository) = LoginAnonymousUseCase(scheduler, repository)

}

登录子组件和登录模块：

@ActivityScope
@Subcomponent(modules = arrayOf(LoginModule::class))
interface LoginSubComponent {
    fun inject(activity: LoginActivity)
}

@Module
class LoginModule {

    @Provides
    @ActivityScope
    fun provideLoginPresenter(loginAccountUseCase: LoginAccountUseCase, loginAnonymousUseCase: LoginAnonymousUseCase)
            = LoginPresenter(loginAccountUseCase, loginAnonymousUseCase)
}

我在 LoginActivity 中注入它，如下所示：

@Inject
lateinit var navigator: Navigator

@Inject <- This inject causes issue
lateinit var presenter: LoginPresenter

override fun onCreate(savedInstanceState: Bundle?) {
 super.onCreate(savedInstanceState)

    appComponent.loginSubComponent().inject(this)
    initView()
    .....
}

此配置导致错误：

/home/user/projects/xxx/app/build/tmp/kapt3/stubs/debug/xxx/presentation/di/component/ApplicationComponent.java:6: error: [xxx.presentation.di.component.LoginSubComponent.inject(xxx.presentation.login.LoginActivity)] xxx.presentation.login.LoginPresenter cannot be provided without an @Inject constructor or from an @Provides- or @Produces-annotated method.

由于这个错误，我现在不能使用 DI，而且我几乎可以肯定 Java 版本在这个配置下应该可以正常工作。你有什么建议吗？
