Java Dagger 2未生成DaggerAppComponent

我在这里多次发现同样的问题。但无论我做什么，都不会生成DaggerAppComponent类。我在这里遵循教程：

在这里：

我正在使用Android Studio 3.0.1

知道我做错了什么吗

我的Gradle文件：

    apply plugin: 'com.android.application'

def daggerVersion = 2.13

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "mjana.testappjava"
        minSdkVersion 17
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    dataBinding {
        enabled true
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

    // RxJava 2
    implementation 'io.reactivex.rxjava2:rxjava:2.1.0'

    // Dagger 2
    annotationProcessor "com.google.dagger:dagger-android-processor:$daggerVersion"
    annotationProcessor "com.google.dagger:dagger-compiler:$daggerVersion"//
    implementation "com.google.dagger:dagger:$daggerVersion"
    implementation "com.google.dagger:dagger-android:$daggerVersion"
}

应用程序文件：

import android.app.Activity;
import android.app.Application;

import javax.inject.Inject;

import dagger.android.AndroidInjector;
import dagger.android.DispatchingAndroidInjector;
import dagger.android.HasActivityInjector;

/**
 * Created by janam on 29.11.2017.
 */

public class App extends Application implements HasActivityInjector {

    @Inject
    DispatchingAndroidInjector<Activity> dispatchingAndroidInjector;

    @Override
    public void onCreate() {
        super.onCreate();

        DaggerAppComponent // Not generated

    }


    @Override
    public AndroidInjector<Activity> activityInjector() {
        return dispatchingAndroidInjector;
    }
}

Dagger的组件生成发生在编译过程中，如果出现任何语法错误——或者Dagger关于无效或缺少绑定或模块的任何错误——Dagger将不会生成组件。也就是说，没有单一的原因使组件无法生成；我们需要查看编译器输出以了解具体问题。请将其编辑到问题中。我添加了Gradle控制台输出。我没有看到匕首的任何东西。是否可以在某个地方打开更详细的输出？我主要是一名C#开发者。Android studio对我来说是全新的。谢谢！以及您的模块和AppComponent.java？我想它很像。
