如何在 Gradle 中使用自定义 Java Annotation Processor? [英] How do I use custom Java Annotation Processor in Gradle?
问题描述
我一直在研究一个简单的 Java 注释处理器,它扩展了 AbstractProcessor
.
I've been working on a simple java annotation processor that extends AbstractProcessor
.
我已经能够使用 javac -Processor MyProcessor mySource.java
问题是使用 Android Studio 将其集成到一个简单的 Hello World android 应用程序中.
The problem is integrating this into a simple Hello World android application using Android Studio.
我首先创建了一个新的 Android 项目,然后添加了一个单独的模块,我将所有注释处理器代码(MyProcessor 类以及它使用的自定义注释)添加到其中.
I started by making a new Android Project, and then adding a separate module where I place all my annotation processor code (the MyProcessor class as well as the custom annotation it uses).
然后我将这个新模块添加为 HelloWorld android 项目的依赖项.
I then added this new module as a dependency of the HelloWorld android project.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':MyProcessorModule')
}
然后我如何使用处理器根据 HelloWorld 应用程序中的所有源文件生成代码?
How do I then use the processor to generate code based on all the source files in the HelloWorld application?
推荐答案
有一个插件可以让它工作.它与 Maven 上的模块完美配合,不确定本地 .jar 文件,但您一定要试一试:
there's a plugin to make it work. It works perfectly with modules that are on Maven, not sure about local .jar files, but you sure give it a try:
这里是插件页面:https://bitbucket.org/hvisser/android-apt
这里是我的 build.gradle:
and here my build.gradle with it:
buildscript {
repositories {
mavenCentral()
}
dependencies {
... add this classpath to your buildscript dependencies
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
}
}
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt' << apply the plugin after the android plugin
dependencies {
// in dependencies you call it
apt 'com.company.myAnnotation:plugin:1.0-SNAPSHOT'
compile 'com.company.myAnnotation:api:1.0-SNAPSHOT'
它应该可以工作.
