title: eclipse import local git repository, two set of same file shown in package explorer
body: <p>In eclipse, I right click my local repository in git repositories view and choose import, after import, I go to package explorer, I see two set of same file shown, as the following image shown (e.g. cfms-db-update folder shown under CFMS in upper and shown in lower also, but lower has grey word [CFMS_staging_kei20201211]).</p>
  <ol>
  <li>why will this happen?</li>
  <li>If I want to change code of a file, as the file shown in both upper part and lower part, where should I change (upper or lower one)?</li>
  </ol>
