我尝试使用新的Jack toolchain构建一个简单的项目。我的项目依赖于android-apt插件（它使用了一些注释处理工具，但是在我尝试添加此工具之前发生了构建错误）。这是我的模块构建脚本（我使用 Android Studio 1.3 和 gradle插件1.3.0 ）：
apply plugin: 'com.android.application'
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.6'
}
}
apply plugin: 'android-apt'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.netimen.ui.demo"
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
useJack=true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
}
当我尝试同步我的项目时，我得到以下ouptup：
Error:Could not find property 'options' on task ':demo:compileDebugJavaWithJack'.
当我尝试运行gradlew assembleDebug --stacktrace时，我得到以下内容：
org.gradle.api.ProjectConfigurationException: A problem occurred configuring project ':demo'.

当我尝试删除 android-apt 插件时，问题就消失了。
答案 0 :(得分：27)
编辑：从最新的Android Gradle插件（2.2）开始，内置了注释处理，同时支持jack。我已将这些步骤写到migrate from android-apt
旧答案：
Jack编译器任务不支持传递注释处理选项，因为它仍然是实验性的。 Jack编译器本身确实支持注释处理，但这还没有在Gradle插件中公开。当发生这种情况时，android-apt可能会更新以支持杰克。
答案 1 :(得分：10)
自Android Studio 2.2预览版以来，您可以将注释处理器与新的Jack编译器配合使用。
如果您希望在编译时应用注释处理器但不包含在APK中，请使用模块级build.gradle中的annotationProcessor依赖范围：
dependencies {
compile 'com.google.dagger:dagger:2.0'
annotationProcessor 'com.google.dagger:dagger-compiler:2.0'
}
您还可以为特定的构建变体应用注释处理器：
debugAnnotationProcessor 'com.google.dagger:dagger-compiler:2.0'
注释处理需要Android Gradle Plugin版本2.2.0-alpha1或更高版本，因此您需要更新到2.2是必需的。要在项目级build.gradle中使用该插件：
classpath 'com.android.tools.build:gradle:2.2.0-alpha1'
您可以在Android Tools Tech Docs或here更详细地了解启动并运行表单中的一些信息，包括有关常用注释处理框架的一些信息，例如Dagger 2
