body: <p>I set up an environment variable (Under <code>IDE Settings -&gt; Path Variables</code>)    </p>
  
  <pre><code> APP_HOME = /path/to/app_home  
  </code></pre>
  
  <p>One of my tests is failing however with      </p>
  
  <pre><code> System.out.println("APP HOME: " + APP_HOME); 
  </code></pre>
  
  <p>With      </p>
  
  <pre><code> APP HOME: null/ 
  </code></pre>
