You should check your configuration for typos. (http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass) Note: there were 2 classes trying to access generic signatures using reflection. You should consider keeping the signature attributes (using '-keepattributes Signature'). (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes) Note: there were 31 unkept descriptor classes in kept class members. You should consider explicitly keeping the mentioned classes (using '-keep'). (http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass) Note: there were 3 unresolved dynamic references to classes or interfaces. You should check if you need to specify additional program jars. (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass) Note: there were 2 class casts of dynamically created class instances. You might consider explicitly keeping the mentioned classes and/or their implementations (using '-keep'). (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclasscast) Note: there were 4 accesses to class members by means of introspection. You should consider explicitly keeping the mentioned class members (using '-keep' or '-keepclassmembers'). (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)

Warning: there were 37 unresolved references to classes or interfaces. You may need to add missing library jars or update their versions. If your code works fine without the missing classes, you can suppress the warnings with '-dontwarn' options. (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
