title: Spring Boot SLF4J Error

  <p>I know this question appears elsewhere on the site, I have tried countless things and nothing works. I am using IntelliJ 2016.1.3, Java version 1.8.0._60.</p>
  
  <p>My pom.xml is:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;

  <p>I have tried maven clean from IntelliJ and no luck. </p>
  
  <p>EDIT: Screenshot added to show everything being pulled into project.

  <p>UPDATE: Completely uninstalled maven 3.3.9 and only have the built in maven from IntelliJ ultimate. Still not working, extremely frustrating. Over a week into this and can't get the 15 minute demo working.</p>
