title: No idea annotations attached to the jdk
body: <p>I have installed Java 8 to my IntelliJ Idea. I have added path to jdk in Idea. And when I start my project I see that message:</p>
  
  <blockquote>
    <p>no idea annotations attached to the jdk
    <a href="https://i.stack.imgur.com/ihUJc.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ihUJc.png" alt="enter image description here"></a></p>
  </blockquote>
  
  <p>What I need to do to fix that?</p>
