How to configure dagger + gradle
提问by Necronet
I have a project and migrating to gradle dependency, but I find myself with an issue trying to setup dagger with gradle, the first time I compile it work perfectly (or if I clean) but if I try it twice then it gives me error like:
我有一个项目并迁移到 gradle 依赖项，但是我发现自己在尝试使用 gradle 设置 dagger 时遇到了问题，我第一次编译它时可以完美运行（或者如果我清理了它），但是如果我尝试两次，它会给我类似的错误：
Error:(13, 14) error: duplicate class: com.myapp.android.application.InjectingApplication$InjectingApplicationModule$$ModuleAdapter
错误：(13, 14) 错误：重复类：com.myapp.android.application.InjectingApplication$InjectingApplicationModule$$ModuleAdapter
I try using android-apt plugin and configured as in the documentation but I still get the same error (https://bitbucket.org/hvisser/android-apt/overview)
我尝试使用 android-apt 插件并按照文档进行配置，但仍然出现相同的错误（https://bitbucket.org/hvisser/android-apt/overview）
I also try using provided dependency instead like in this tutorial (https://github.com/frankdu/android-gradle-dagger-tutorial) of compile but no luck so far.
我也尝试使用提供的依赖项，而不是像在编译的本教程（https://github.com/frankdu/android-gradle-dagger-tutorial）中那样，但到目前为止还没有运气。
Do you have any ideas how to configure dagger and gradle?
您对如何配置 dagger 和 gradle 有任何想法吗？

My build.gradle looks like this
我的 build.gradle 看起来像这样
apply plugin: 'android'
apply plugin: 'android-apt'
android {
compileSdkVersion 19
buildToolsVersion "19.0.2"
defaultConfig {
minSdkVersion 9
targetSdkVersion 19
packageName "com.myapp.android"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile project(':volley')
apt 'com.squareup.dagger:dagger-compiler:1.2.0'
compile 'com.squareup.dagger:dagger:1.2.0'
}
And my top level build.gradle look like this
我的顶级 build.gradle 看起来像这样
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.9.+'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.2'
}
}
allprojects {
repositories {
mavenCentral()
}
}

I tried with provided again as @Marco suggested no luck, I don't know if there is a library or a version of gradle that could be causing this problem, I'm currently using 1.10. On the bright side I did find a way to make it work, but I would love to do it by just adding the provided statement. The way I did it is the old way:
我再次尝试提供，因为@Marco 建议没有运气，我不知道是否有可能导致此问题的库或 gradle 版本，我目前使用的是 1.10。从好的方面来说，我确实找到了一种使它工作的方法，但我很乐意通过添加提供的语句来做到这一点。我这样做的方式是旧的方式：
Define apt configuration
定义apt配置
configurations {
apt
}
add Dagger compiler lib
添加 Dagger 编译器库
apt 'com.squareup.dagger:dagger-compiler:1.2.0'
And implement the this hook to applicationVariant which as far as I know android-apt does something similar. Does this make sense? why?
并将这个钩子实现到 applicationVariant，据我所知 android-apt 做了类似的事情。这有意义吗？为什么？
def getSourceSetName(variant) {
return new File(variant.dirName).getName();
}
android.applicationVariants.each { variant ->
def aptOutputDir = project.file("build/source/apt")
def aptOutput = new File(aptOutputDir, variant.dirName)
android.sourceSets[getSourceSetName(variant)].java.srcDirs+= aptOutput.getPath()
variant.javaCompile.options.compilerArgs += [
'-processorpath', configurations.apt.getAsPath(),
'-s', aptOutput
]
variant.javaCompile.source = variant.javaCompile.source.filter { p ->
return !p.getPath().startsWith(aptOutputDir.getPath())
}
variant.javaCompile.doFirst {
aptOutput.mkdirs()
}
}

I am using dagger in this sample Volley Examples. I'm not experiencing any problems with dagger and I'm including the compiler using:
我在这个示例Volley Examples 中使用了匕首。我在使用 dagger 时没有遇到任何问题，我将编译器包括在内：

Update Gradle plugin to (root/gradle) classpath 'com.android.tools.build:gradle:2.2.0'
将 Gradle 插件更新到 (root/gradle) 类路径 'com.android.tools.build:gradle:2.2.0'
app/gradle
应用程序/gradle
compile 'com.google.dagger:dagger:2.4'
annotationProcessor 'com.google.dagger:dagger-compiler:2.4'

It is work for me.
这对我来说是工作。
Step 1:
Add this code to you build.gradle
第 1 步：
将此代码添加给您build.gradle
provided 'com.squareup.dagger:dagger-compiler:1.2.2'
Step 2:
Add source code folder app/gento you project. So you can add this code to you app/build.gradle(src/main/javais you project core code folder)
第 2 步：
将源代码文件夹添加app/gen到您的项目中。所以你可以添加这个代码给你app/build.gradle（src/main/java你是项目核心代码文件夹）
sourceSets.main {
java.srcDirs = ['src/main/java', 'gen']
}
