title: Using external jars in Play framework
body: <p>Recently, I tried to use java-image-scaling library to resize the image files. So, I set java-image-scaling jar file through Eclipse as a way that usual Eclipse project sets its external jar file. In Eclipse, there is no error (I mean, there is no red underline.) to use java-image-scaling library. However, when I try to compile it through Play! console, the compiler said it cannot find java-image-scaling jar file. It is weird because I did exactly same with Joda Time library and there was no problem. </p>
  
  <p>Am I missing something to use external jar(java library) in a project of Play framework?</p>

  <p>Check this screenshot that shows I already added Joda datatime library and java-image-scaling library.</p>
