title: Gulp copy source failing because of .framework folder
body: <p>I'm trying to run a command that copies my project content into another folder and I keep having this error:</p>
  
  <pre><code>Error: EISDIR: illegal operation on a directory, read
  </code></pre>
  
  <p>I narrowed it to know that is the .framework folder that is causing the problem. If I delete it It works ok. The problem is that I need that folder in the project because I'm making an InDesign HTML plugin a PluPlug framework is needed.</p>
  
  <p>This is my env:</p>
  
  <pre><code>Mac OSX 10.11.6
  npm -v 4.0.5
  node -v 7.4.0
  gulp -v CLI version 1.2.2Local version 3.9.1
  </code></pre>
