title: JsonMethods is not a member of package org.json4s.jackson
body: <p>I'm using json4s in my scala 2.12 application. I added this maven dependency -</p>
  <p><code>org.json4s:json4s-jackson_2.12:4.0.0</code></p>
  <p>I have these imports in the code -</p>
  <pre><code>import org.json4s._
  import org.json4s.jackson.JsonMethods._
  </code></pre>
  <p>As per the doc, this should work - <a href="https://github.com/json4s/json4s" rel="nofollow noreferrer">https://github.com/json4s/json4s</a></p>
  <p>What am I doing wrong ?</p>
