Obfuscating jar file using proguard

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.

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.**".
