title: unable to resolve jar dependencies for annotation processor
body: <p>I have an annotation processor that depends on an external jar - lib.jar
  I'm packaging my processor as a jar and using it while compiling my client.
  I had it working fine until I introduced lib.jar when the client compilation started failing with this message.</p>
  
  <pre><code>Exception thrown while constructing Processor object: java.lang.NoClassDefFoundError: com/foo/FooBar
  </code></pre>
  
  <p>I tried placing lib.jar in the classpath for my client but it didn't help. What am I missing?</p>
