title: ProGuard warnings: there were 7 unresolved references to program class members
body: <p>ProGuard stops with a lot of warnings:</p>
  
  <blockquote>
    <p>Warning: there were 1221 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.

    <p>Warning: there were 37 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.

    program class members.
             Your input classes appear to be inconsistent.
             You may need to recompile the code.

  <p>But my jar runs correctly. I am not quite familiar with proguard setting. Any suggestion?</p>
