title: Intellij IDEA can't find a class in successfully imported Maven dependency
body: <p>I'm trying to run the first json-simple example from this page <a href="https://code.google.com/p/json-simple/wiki/EncodingExamples">https://code.google.com/p/json-simple/wiki/EncodingExamples</a> in my project.</p>
  
  <p>I've added a maven dependency in my pom.xml from this page <a href="http://mvnrepository.com/artifact/com.googlecode.json-simple/json-simple/1.1.1">http://mvnrepository.com/artifact/com.googlecode.json-simple/json-simple/1.1.1</a></p>
  
  <p>Intellij IDEA says that everything is fine, dependency is successfully imported. However, it cannot find any json-simple classes in the editor, saying "Cannot resolve symbol 'JSONObject'.

  <p>What can be wrong? I had similar issues with adding other dependencies, but i could "solve" them by downloading the necessary jar and adding it as a dependency without using maven.</p>
  
  <p>Appreciate any help</p>
  
  <p>Thank you</p>
