android - para - Dagger 2 no está generando mi clase de componente

dagger android support

Question

Estoy trabajando con Dagger 2 para crear mi inyección de dependencia. Funcionó hace unas horas pero ahora los componentes ya no se generan.

Aquí es donde estoy creando los componentes:

public class App extends Application {
CacheComponent mCacheComponent;
ApiComponent mApiComponent;
DataBaseComponent mDataBaseComponent;
@Override
public void onCreate() {
super.onCreate();
mCacheComponent = DaggerCacheComponent.builder()
.cacheModule(new CacheModule(getApplicationContext()))
.build();
mApiComponent = DaggerApiComponent.builder()
.apiModule(new ApiModule())
.build();
mDataBaseComponent = DaggerDataBaseComponent.builder()
.dataBaseModule(new DataBaseModule(getApplicationContext()))
.build();
}
public CacheComponent getCacheComponent(){ return mCacheComponent;}
public ApiComponent getApiComponent() { return mApiComponent; }
public DataBaseComponent getDataBaseComponent() { return mDataBaseComponent;}
}

Esto estaba funcionando pero ahora recibo errores:

Estaba usando la misma configuración todo el día, pero ahora no sé dónde podría estar el problema y por qué no genera la clase de componentes.

ApiComponent.

@Singleton
@Component(modules = {
ApiModule.class,
DataBaseModule.class
})
public interface ApiComponent {
void inject(ServiceDownloaderPlayList service);
}

CacheComponent

@Singleton
@Component(modules = {
CacheModule.class
})
public interface CacheComponent {
void inject(VideoPlayerFragment fragment);
}

DataBaseComponent

@Singleton
@Component(modules = {
DataBaseModule.class
})
public interface DataBaseComponent {
void inject(ServiceDownloaderPlayList service);
}

Consejos

Cuando comento el DataBaseComponent o ApiComponent todo funciona.

Answer 1

si está utilizando el plugin apt como sigue

classpath ''com.neenbedankt.gradle.plugins: android-apt: 1.8'' aplica el complemento: ''com.neenbedankt.android-apt''

luego incluir

apt "com.google.dagger: dagger-compiler: $ DAGGER_VERSION"

junto con

compile "com.google.dagger: dagger: $ DAGGER_VERSION"

en el nivel de módulo build.gradle

Además del problema de configuración Dagger2 tampoco generará las clases de Componente si hay algún error (muy probablemente un error de sintaxis) en el módulo o clases dependientes.

simplemente abra las clases dependientes y solucione el problema si hay alguna y vuelva a compilar el proyecto.

Un poco de caché invalidante también funciona: Android Studio-> file-> invalida el caché y reinicia
