title: Intellij, target JRE vesion doesn't match project jdk version
body: <p>I am using Intellij Community version 2019.3 on my MacBook. I have a simple springboot (java) project. Whenever I run my unit test I get the following warning:</p>
  
  <p><a href="https://i.stack.imgur.com/3b7Px.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3b7Px.png" alt="enter image description here"></a></p>
  
  <p>Where should I check on Intellij to get rid of this error? (I heard on internet "Project Settings", but I can't find where this option is)</p>
