This is the output from the ant build

What am I doing wrong. It is supposed to be generating the .java files that will be used to make the very class its complaining about...
Thanks in advance for your help,

The Author.hbm.xml was my own creation (as minor as it was) trying to learn to use hibernate from some simple testing. The key thing was that the type wasnt being defined. The problem was resolved once I added the type="String" and so forth. Thanks for the feedback.
