title: package org.springframework.stereotype does not exist and more
body: <p>I have a web application project using Spring and IntelliJ, and it's been working great so far, but today I tried to run it and it starting giving me this errors</p>
  
  <p>This is just a small part </p>

  <p>There's more errors but they're basically the same as above. I don't know what happened, I've tried to reimport the "pom.xml" but it does nothing. I've deleted and cloned the project a few times already.</p>
  
  <p>Thanks in advance</p>
