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

所以我将代码 -ignorewarnings 添加到 proguard 配置文件中,所以警告都消失了,但是当我运行应用程序时,标题中的错误会发生。
最佳答案
在一个外包项目中遇到了同样的问题,开发人员似乎已经使用了世界上所有可能的免费库。
最安全的方法是向 ProGuard 提供原始库作为引用,即使其中一些已被弃用并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
阿瓦隆 LogKit - http://www.jarfinder.com/index.php/jars/versionInfo/17610
J2EE 引用 - http://www.jarfinder.com/index.php/jars/versionInfo/4598
下载所有 jar 后,将 ProGuard 指向它们:
# 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
