title: Eclipse Git: Can't add folder to index
body: <p>I'm using Eclipse for a Game Project using LibGdx as framework and Grandle (god I hate it). </p>
  
  <p>I'm trying to push the repositories to GitHub, but I can't stage the "core" folder in the commit. It's considered unstaged. </p>
  
  <p>When I try RightClick -> "Add to Index" it does and says nothing...</p>

  <p>As it maybe usefull to know, the g2 project someway "contains" HarakaGameTwo-core &amp; HarakaGameTwo-Desktop projects through Gradle...</p>
  
  <p>Any idea how can I stage this folder ?</p>
