问题运行proguard的单罐子 - 找不到Java类

Question

我试图使用ProGuard优化罐子

我的配置：java -jar proguard.jar @myconfig.pro -verbose

：

-injars  MyLib-1.0.jar 
    -outjars  MyLib-1.0.proguard.jar 
    -libraryjars retrace.jar 
    -libraryjars guava-18.0.jar 
    -printmapping MyLib.map 

    -keep public class MyLib { 
     public String myPublicCallEntryPoint(java.lang.String); 
    } 

    -keep public class * { 
     public protected *; 
    } 

    -keepclassmembernames class * { 
     java.lang.Class class$(java.lang.String); 
     java.lang.Class class$(java.lang.String, boolean); 
    } 

然后，我运行日志输出：

Initializing... 
Note: the configuration refers to the unknown class 'String' 
Note: the configuration refers to the unknown class 'java.lang.String' 
Note: the configuration refers to the unknown class 'java.lang.Class' 
Note: the configuration refers to the unknown class 'java.lang.String' 
Note: the configuration refers to the unknown class 'java.lang.Class' 
Note: the configuration refers to the unknown class 'java.lang.String' 

有什么办法可以防止这种事情发生？如何让proguard识别基类的Java类？

问题是我从JRE错误rt.jar与从proguard包回溯。
