Warning:there were 126 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://ift.tt/1a4OICW)

Warning:there were 5 instances of library classes depending on program classes. You must avoid such dependencies, since the program classes will be processed, while the library classes will remain unchanged. (http://ift.tt/1m0XnLG)

Warning:there were 3 unresolved references to program class members. Your input classes appear to be inconsistent. You may need to recompile the code.

Anybody has an idea of what this can be? I've been searching but I cant find anything.

Sorry, for all the log mess ..

Thank you
