title: An internal error occurred during: "C/C++ Indexer".java.lang.NullPointerException
body: <p>I'm totally new with <code>cocos2d-x</code>.<br>
  I had problem when using <code>cocos2d-x-3.3rc0</code> in OS X 10.9  </p>
  
  <p>I create project by using command line :<br>
  <code>python cocos.py new ProjName --package .....</code><br>
  It created a <code>ProjName</code> for me.<br>
  I import the <code>proj.android</code> to build and run, for the first time, every thing seem to be OK.  </p>
  
  <p>But the next day, when i open it, the problem occurred.  </p>
  
  <pre><code>"An internal error occurred during: "C/C++ Indexer".java.lang.NullPointerException"
  </code></pre>
  
  <p>In <code>C/C++ perspective</code> in Eclipse, it look like a empty project (there's nothing in that project - in <code>Java perspective</code>, it does), and i can't do anything with it.<br>
  The <code>proj.ios_mac</code> still work fine.<br>
  Please help me !</p>
