title: "Cannot find symbol" error in open source software project
body: <p>I am looking to edit an open source software which I downloaded from SourceForge, but before editing anything I decided to run the "build" xml file through ANT, and create a jar executable to test everything initially. </p>
  
  <p>As soon as I build the project, it displayed several errors in one of the class. All the errors are for "Cannot Find symbol..."</p>
  
  <p>But when I opened the file in Eclipse, everything seems to be fine. So what should I do about this, from where should I proceed next?</p>
  
  <p>If needed, I can also post the link of the software that I am talking about.</p>
