title: How to index entire GOPATH for existing project in Goland?
body: <p>When I create a project, I forgot to check [index entire GOPATH]. So currently, the project can't find third party modules.</p>
  
  <p>Even though I checked <code>[index entire GOPATH]</code> option for this project in <code>Preferences | Go | GOPATH | Project GOPATH</code>, the project doesn't index the entire GOPATH.</p>

  <p>Edit:</p>
  
  <p>I deleted .idea directory and opened the project again, it works fine now.</p>
