如何在Gradle上触发最小任务以运行apt插件

Question

我正在创建一个编译时注释处理器，以在Android上生成一些代码。

为了触发注释处理器，我使用了来自hvisser https://bitbucket.org/hvisser/android-apt/overview的android-apt插件

此刻，在我对Processor extends AbstractProcessor所做的每处更改上，我都要Processor extends AbstractProcessor我必须运行完整的/.gradlew clean build才能查看结果，即使对于很小的示例项目，这也是一个缓慢的过程。

所以我的问题是，有什么我可以用来触发注释处理器的gradlew tasks吗？

我当前的./gradlew tasks的输出为：

------------------------------------------------------------
All tasks runnable from root project
------------------------------------------------------------

编译时会生成源代码。 因此，您需要运行gradlew cleanCompileDebugSources compileDebugSources 。 这是相同的是什么，当你的Android Studio的运行make从你的项目build菜单。

如果您将注释处理器作为项目的一部分进行开发，则可以在android-apt使用processor选项，而无需打包处理器项目。 这是假设您将处理器模块作为apt project(':myprocessor')依赖项（ compile也将起作用）。

apt {
    processor "my.class.name"
}
