android - 没有使用maven将注释处理(生成的)源编译成apk

Question

我尝试使用 Maven 和 androidannotations构建我的 apk，但独立于任何 IDE(我实际上使用的是 IntelliJ IDEA 而不是 Eclipse，但我希望它完全独立于 IDE，这样它也可以在任何构建服务器上完美运行)。

注释似乎得到了正确处理，但它们没有被编译到 apk 中，这是我目前遇到的问题。

我尝试使用 <includes> maven-compiler-plugin 部分，并且路径应该是正确的——它存在并且还包含注释处理、生成、java 类，这是 Android 主要 Activity 但带有下划线 (_) 后缀。

有一个 wiki 页面描述了如何使用 Maven+Eclipse，但是它与 Eclipse IDE 的绑定(bind)太多了。 https://github.com/excilys/androidannotations/wiki/Building-Project-Maven-Eclipse所以它不能帮助我解决问题。

这是我的 pom.xml:

mvn install甚至给我看 -s具有正确路径的编译器选项:

[INFO] javac option: -processor

(mvn install的完整日志在这里:http://pastebin.com/6dQkcNXD)

但仍然运行 apk 失败:

E/AndroidRuntime( 6942): Caused by: java.lang.ClassNotFoundException: com.mycompany.myproject.activity.HelloAndroidActivity_ in loader dalvik.system.PathClassLoader

并处理了注释 HelloAndroidActivity_不在 apk/classes.dex 中。

发现问题:<extensions>true</extensions>在 maven-compiler-plugin 下丢失:

   <plugin>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>2.3.2</version>
       <configuration>
