Question

I\'ve try obfuscate our web application which use spring, jaxb and relies on annotations, and reflection heavily. I apply many recipes found in internet to keep some classes

Answer 1

Thanks to http://sourceforge.net/p/proguard/discussion/182455/thread/1c28f199/ I found solution for my question (<⁠fields> must be added):

-keepclassmembers class * extends java.lang.Enum {
    <fields>;
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

Answer 2

This worked fine for me.

-keep public enum com.company.appname.**{
    *;
}

Where ** is package and subpackages.
