title: Cannot resolve json import Intellij after adding dependency and library .jar
body: <p>I cannot seem to resolve this issue after adding the json-lib-2.4-jdk15.jar from an online source to the project dependencies, screenshots provided to show walkthrough of what I am doing. (and yes I have repeatedly tried "Invalidate caches and restart")</p>
  
  <p><strong>The error:</strong>

  <p>This is my Project Structure ("cmd + ;" or "File > Project Structure")</p>

  It doesn't seem to work on "Scope" set to Compile either. Note that I added the .jar file as a library too because I'm just really unsure as to why I can't get this to work. Any help is greatly appreciated, thanks. </p>
  
  <p>What do I seem to be doing incorrectly here?</p>
