title: Intellij - Generated source code should not be edited (even though it's not generated)
body: <p>I have a file that just exports a few modules:</p>
  
  <pre><code>export * from './A'
  export * from './B'
  export * from './C'
  </code></pre>
  
  <p>But now when I try adding more exports, I get a warning at the top of the file saying:</p>
  
  <p><code>Generated source code should not be edited.  The changes will be lost when sources are regenerated.</code> </p>
  
  <p>I'm not really sure what that means since I manually type the export lines as I add more modules.  The warning actually disappears if I add some normal js code like a random function (compared to just having exports).</p>
  
  <p>Should I be concerned with the warning? How do I make it go away?</p>
  
  <p>I'm using WebStorm 2016.2 EAP.</p>
