目标覆盖不按预期工作

Question

我遇到了这个问题，我的build.xml文件为Android项目。

我已经基本上从android SDKs build.xml文件中将“-compile”目标复制到我自己的build.xml文件中。但是，在运行ant时，它会继续在Android SDK的build.xml文件中使用“-compile”目标而不是我的。我阅读过的所有地方，包括我的build.xml文件的注释，都表明这是目标覆盖的工作方式，但由于某种原因，我的覆盖目标未运行。

有什么我需要做的吗？

感谢帮助！

UPDATE：

我专门做这个的-compile目标注释掉<fileset dir="${source.absolute.dir}" excludes="**/*.java ${android.package.excludes}" />线。

正如您在下面看到的那样，有两种不同的回声语句。我一直在看到打印的sdk/tools/build.xml文件。另一个明显的迹象是，构建失败，因为它没有使用我的目标。

这里是我的custom_rules.xml文件的目标

<target name="-compile" depends="-pre-build, -build-setup, -code-gen, -pre-compile">

     <!-- if the project is instrumented, intrument the classes -->

这里是SDK /工具/ build.xml文件相同的目标：

从默认覆盖构建目标build.xml，你应该把你的自定义目标放在一个名为custom_rules.xml的文件中。
