maven 不会编译源文件夹

Question

我从 ant 切换到 maven 来构建 android 项目。但是我发现用 android-maven 插件配置我以前的 ant 项目非常困难。在我将这个项目配置为与官方示例项目相同后，除了主项目下的源文件夹尚未编译外，一切正常。我已经检查了很多次 pom.xml，但是示例项目下的同一个 pom.xml 工作正常，但在我自己的项目中却不行。

通过检查目标文件夹中的classes文件夹发现src没有编译。

这是我的 pom.xml：

似乎是源目录层次结构不适合maven造成的。

对于普通的 android 项目，src 层次结构是src/com/a/b，但对于 maven，是 `src/main/java/com/a/b'。
