title: package org.apache.commons.lang3.time does not exist in idea java Scratch file
body: <p>When I create a new Java scratch file in Intellij with this code:</p>
  
  <pre><code>import java.util.Date;
  import org.apache.commons.lang3.time.DateFormatUtils;
  
  class Scratch {
  
      public static void main(String[] args) {
          System.out.println(DateFormatUtils.format(new Date(), "yyyyMMddHHmmss"));
      }
  }
  </code></pre>
  
  <p>It shows  </p>
  
  <blockquote>
    <p>"Error:(2, 37) package org.apache.commons.lang3.time does not exist".  </p>
  </blockquote>
  
  <p>I only can use the jdk lib.<br>
  How can I modify the classpath used to run Intellij scratch files ?</p>
