我已经使用应用内计费创建了应用程序，现在我想混淆我的代码以缩短破解它的机会。但是proguard设置存在一些问题。我正在尝试通过本教程进行设置。我的项目结构很常见，主项目引用了其他具有所有功能的应用内服务的项目。我已经停止了执行带有代码混淆的 ant 发布的最后一步。我一直收到：

该错误通知我没有找到某些东西，但是什么以及如何解决它？
另一件事，当我在第二步时，没有混淆的未签名项目的 ant 版本我收到了成功，但有一些通知：“看起来你有子项目，如果有，请使用 --subprojects 命令”。我尝试添加此参数并在没有很长时间的情况下完全成功，但我无法更新子项目。我m not sure it很坏与否。请你也帮我解决这个问题。
