title: cannot be resolved to a Type Jaspersoft Studio
body: <p>Using jaspersoft Studio 6.1.1</p>
  
  <p>What i'm trying to achieve is to transform the numbers i get to the Roman format, and for that i added a .jar that i created to do the job, the problem is, when i'm trying to use the functions in my .jar, i get the errors below:</p>

  <p>RomanNumeral is the name is the .jar and the class.</p>
  
  <p>I looked everywhere for a similar error and that didn't help</p>
  
  <p>any idea why this happens?</p>
