Dagger 2和android Studio：工作但看不到生成的类

I'm trying to use Dagger 2 in an Android Studio Project. I've used the CoffeeMaker example. I've managed to make the app build and working however: - I don't success in seeing the generated code. - If I debug, I can't see it neither. - Moreover DaggerCoffeeApp_Coffee as marked as reed (Cannot resolve symbol)

我正在尝试在Android Studio项目中使用Dagger 2。我用过CoffeeMaker的例子。我设法使应用程序构建和工作: - 我没有成功看到生成的代码。 - 如果我调试,我也看不到它。 - 此外DaggerCoffeeApp_Coffee标记为芦苇(无法解析符号)

My gradle files are:

我的gradle文件是:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

and

apply plugin: 'com.android.application'


android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.mateuyabar.android.dagger2test"
        minSdkVersion 22
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {
        abortOnError false // ignoring some references from dagger-compiler
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'javax.inject:javax.inject:1'
    compile 'javax.annotation:javax.annotation-api:1.2'
    compile 'com.google.dagger:dagger:2.0'
    provided 'com.google.dagger:dagger-compiler:2.0'
    provided 'org.glassfish:javax.annotation:10.0-b28'

}

Use the Android-Apt plugin by Hugo Visser:

使用Hugo Visser的Android-Apt插件:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    // the latest version of the android-apt plugin
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
  }
}

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.mateuyabar.android.dagger2test"
        minSdkVersion 22
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {
        abortOnError false // ignoring some references from dagger-compiler
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'javax.inject:javax.inject:1'
    compile 'javax.annotation:javax.annotation-api:1.2'
    compile 'com.google.dagger:dagger:2.0'
    apt 'com.google.dagger:dagger-compiler:2.0'
    provided 'org.glassfish:javax.annotation:10.0-b28'
}

Note the apt 'com.google.dagger:dagger-compiler:2.0' line as well. This should make the generated sources visible for AS.

请注意apt'com.google.dagger:dagger-compiler:2.0'行。这应该使生成的源对AS可见。

I stumbled upon same problem, in my case I was testing new classes and tried to inject them separately into my main class, in that case Dagger won't generate any DaggerComponents from factory.

我偶然发现了同样的问题,在我的情况下,我正在测试新类并尝试将它们分别注入我的主类,在这种情况下,Dagger不会从工厂生成任何DaggerComponents。

Simply, remember to put all injections that goes into one class in one Module & one Component. You cannot inject more than one DaggerComponent into one class. Besides that's the point of those components, to aggregate injected classes

简单地说,记住将所有注入放入一个模块和一个组件中的一个类中。您不能将多个DaggerComponent注入一个类。除了那些组件的重点,聚合注入的类
