使用Proguard混淆jar文件

Question

I used proguard to obfuscate my jar file. During processing I got the following errors:

Initializing...
Warning: tdvep.jmNb: can't find referenced class QSYGWO
Warning: tdvep.qmfsfjttKdvEpNz: can't find referenced class FVTYBN
Warning: tdvep.qsfboBcSw$qsffmtssf: can't find referenced class UGKTLU
Warning: tdvep.qsffmtssf: can't find referenced class DREQUQ
Warning: there were 4 unresolved references to classes or interfaces.
         You may need to specify additional library jars (using '-libraryjars').

Please correct the above warnings first. So guide me to resolve this warnings.

Answer 1

Have you checked the ProGuard troubleshooting section - Problems while processing .

If there are unresolved references to classes or interfaces , you most likely forgot to specify an essential library . For proper processing, all libraries that are referenced by your code must be specified, including the Java run-time library. For specifying libraries, use the -libraryjars option.

For example, if ProGuard complains that it can't find a javax.crypto class, you probably still have to specify jce.jar, next to the more common rt.jar.

If you're missing a library and you're absolutely sure it isn't used anyway, you can try your luck with the -ignorewarnings option, or even the -dontwarn option . Only use these options if you really know what you're doing though.

For example, if you're developing for Android , and ProGuard complains that it can't find a java.awt class , then some library that you are using is referring to java.awt . This is a bit shady, since Android doesn't have this package at all, but if your application works anyway, you can let ProGuard accept it with "-dontwarn java.awt.**" .
