title: Why does IntelliJ give me "Package doesn't exist" error?
body: <p>I'm trying to use the barbecue barcode printing library. I have successfully added the library to IntelliJ through project structure add library.  Then I imported the packages and wrote the methods, which gave me no error.  The packages were available in the class.</p>
  <p>But when I compile it gives me the error:</p>
  <pre><code>error: package net.sourceforge.barbecue does not exist
  </code></pre>
  <p>How can this be?</p>
  <p>I'm coding in ubuntu, is there any other place to which I have to add the library?</p>
