title: Whats the matter of the folder hierarchy my project in IntelliJ IDEA?
body: <p>Today when I open my project, there is some problem in my folder hierarchy, you can see the below, there is no packages here:</p>
  
  <p><kbd><a href="https://i.stack.imgur.com/RBiTH.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RBiTH.jpg" alt="enter image description here"></a></kbd></p>
  
  <p>In general, the common folder hierarchy should like this:</p>
  
  <p><kbd><img src="https://i.stack.imgur.com/bcpBb.jpg" width="333"></kbd></p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I have tried reopen the project and reopen my IntelliJ IDEA.
  Both do not work.</p>
