maven中添加proguard来混淆代码
一步步教你使用Proguard混淆Java源代码 http://java-server.iteye.com/blog/1166114
直接使用mvn package可能直接出错，所以先用jar:jar命令得到jar文件，在使用proguard:proguard混淆。
命令在idea的Maven Projects查看。

com.pyx4me=>com.github.wvengen,版本号要变成2.0.7

-allowaccessmodification
#确定统一的混淆类的成员名称来增加混淆
-useuniqueclassmembernames
#这里添加你不需要混淆的类
-dontwarn javax.crypto.**
-keep class javax.crypto.**
-keep class com.rh.hasp.util.** {*;}

-keep public class * extends javax.servlet.Servlet

# ———保护所有实体中的字段名称———-
-keepclassmembers class * implements java.io.Serializable {

}
# ——— 保护类中的所有方法名 ————
-keepclassmembers class * {
public <methods>;
}
执行:mvn package

这时就已经好了，但是包结构都变了，成了a,b,c,d ….的了
虽然是混淆加密了，但是外部也不能再直接使用类来…地去引用了
