  <p>If I build this project with gradle, the shadow plugin generates a fat jar, which runs from the console nicely, it includes the logger, but from the IDE I'm having difficulties finding the LoggerFactory. I read here that I should add the logger to the classpath but since I don't explicitly include a jar, rather than marking it as a dependency, I'm not sure how this would be possible.</p>
  
  <p>Please advise.
  Cheers!</p>
