当我为android启用proguard时，proguard会混淆应用程序中包含的所有jar。这些罐子包括：
在构建已签名的jar时，我得到以下转储：

实际上这个项目是关于新浪微博的SDK，当我使用proguard对其进行模糊处理时，我总是失败，错误如下：

所以我将代码-ignorewarnings添加到proguard配置文件中，所以警告全部被驳回，但是当我运行应用程序时，标题中的错误将会发生。

在外包项目中遇到同样的问题，似乎开发人员已经使用了世界上所有可能的免费图书馆。
最安全的方法是为ProGuard提供原始库作为参考，即使其中一些已被弃用且可能永远不会被您的代码调用：
Log4J - http://logging.apache.org/log4j/1.2/download.html
阿瓦隆 - http://www.docjar.com/jar_detail/avalon-framework-4.2.0.jar.html
Avalon LogKit - http://www.jarfinder.com/index.php/jars/versionInfo/17610
J2EE参考 - http://www.jarfinder.com/index.php/jars/versionInfo/4598
下载完所有的罐子后，请将ProGuard指向他们：
# Apache commomns-logging fun
-libraryjars proguard_ref_lib/log4j-1.2.17.jar
-libraryjars proguard_ref_lib/avalon-framework-4.2.0.jar
-libraryjars proguard_ref_lib/avalon-logkit-2.2.1.jar
-libraryjars proguard_ref_lib/servlet-api-6.0.16.jar
# Apache commomns-logging fun ends
享受

我会尝试commons-logging-1.1.1。似乎版本不匹配
