ProGuard混淆的时候报错了？？？

[Java_yR_26]

在用ProGuard进行操作的时候，报了以下错误？

You might consider explicitly keeping the mentioned classes and/or
their implementations (using '-keep').
Warning: there were 1 unresolved references to superclasses or interfaces.
You may need to specify additional library jars (using '-libraryjars'),
or perhaps the '-dontskipnonpubliclibraryclasses' option.
Warning: there were 3 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile them and try again.
If you are sure the mentioned classes are not used anyway,
you could try your luck using the '-ignorewarnings' option.
Please correct the above warnings first.
