[英]Dagger build error
我有兩個對象,我用dagger2注入沒有任何問題。 當我添加第三個(與之前的兩個相同的方式)時,項目不會重建並給出錯誤,這指向前兩個(這里沒有添加第三個):
error: com.google.firebase.database.DatabaseReference cannot be provided without an @Inject constructor or from an @Provides- or @Produces-annotated method.
com.google.firebase.database.DatabaseReference is injected at
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.ui.splash.SplashPresenter.freeDaysCloudReference
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.ui.splash.SplashPresenter is injected at
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.providers.components.MainPresenterComponent.inject(destination)
每三個模塊和組件以相同的方式實現。 當然,當我刪除添加的第三個時,項目很容易編譯。
混淆項目構建的模塊:
@Module
public class MainPresenterModule {
private final MainPresenter presenter;
public MainPresenterModule(MainPresenter presenter) {
this.presenter = presenter;
}
@Singleton
@Provides
MainPresenter provideMainPresenter() {
return presenter;
}
}
零件:
@Singleton
@Component(modules = {MainPresenterModule.class})
public interface MainPresenterComponent {
void inject(SplashPresenter destination);
}
也許有用:我用dagger2將這些庫用於DI:
implementation 'com.google.dagger:dagger-android:2.11'
implementation 'com.google.dagger:dagger-android-support:2.11'
annotationProcessor 'com.google.dagger:dagger-android-processor:2.11'
annotationProcessor 'com.google.dagger:dagger-compiler:2.11'
在mac osx上使用最新的android studio(3.1.1)和gradle(3.1.1)。 當然我已經嘗試過無效緩存和重新啟動,清理等等。我檢查了導入,所有這些都是相同的。
編輯:當我刪除注入的使用
@Inject
DatabaseReference shopsCloudReference;
public MainPresenter(MainController controller) {
super(controller);
Core.injectShopsComponent().into(this);
}
和
@Inject
DatabaseReference freeDaysCloudReference;
public SplashPresenter(SplashController controller) {
super(controller);
Core.injectFreeDaysComponent().into(this);
}
項目編譯,但它不是我想要的。
編輯有很多答案,我沒有在gradle中添加firebase庫。 我全力以赴:

好吧,你寫道:
@Component(modules = {MainPresenterComponent.class})
它應該是 :
@Component(modules = {MainPresenterModule.class})
