我正在研究这个问题超过一个小时：
我有一个android项目，因为我在编译时做自定义步骤，我使用ANT编译项目并生成APK文件。
1-如果我使用ant：
的“愚蠢”命令行ant init_debug
编译android应用程序并创建apk文件;它通过我的自定义步骤（我有“echo”指令显示我的自定义步骤，它们在命令行中打印）。
2-如果我要求Eclipse运行我的自定义构建文件，它会失败并且Eclipse会回答：
Buildfile: /home/[...]/custom_rules.xml
BUILD FAILED
Target "clean" does not exist in the project "null". It is used from target "myrelease".
Total time: 95 milliseconds
第24行是什么？ ＆lt; target＆gt;
中通常的和通用的依赖声明<target name="init_debug" description="Initialize pre build and do DEBUG" depends="clean, debug">
a）我运行“android update project -p”。好几次
b）我关闭并重新打开Eclipse（值得一试！我看到奇怪的事情像过去那样解决了！）
c）我的build.xml以＆lt; project＆gt;开头。用我的项目名称，所以我尝试了“myproject.clean”而不是简单地“干净”作为依赖而没有成功
d）我也试过“android_rules.clean”，结果相同
e）我的custom_build.xml也以＆lt; project＆gt;开头，但我没有添加任何名称属性。
我的想法已经用完了，欢迎任何帮助！
我的完整custom_rules.xml如下：
