title: Package com.google does not exist
body: <p>I'm using Netbeans IDE 7.0.1.
  I base my question on the CalculatorApp sample application available with the IDE.
  The sample is running fine but I wish I could use some JSON, ad so I download google-gson-stream-1.7.1.jar library, and included it in my libraries :
  - right click on "Library", then "Properties" then "Add JAR/Folder" and selected my JAR (located somewhere in "My Documents/Download".</p>
  
  <p>The problem is that when i type the following :</p>
  
  <pre><code>import com.google.gson;
  </code></pre>
  
  <p>(or even com.google), the IDE fires a "Package com.google does not exist". The JAR and its hierarchy is correctly shown on the left side pane,in the "Libraries" section. Most surprising, the IDE can autocomplete the com.google.<strong>**</strong> stuff.</p>
  
  <p>AFAIK, I need to further to get this work, don't I ? Any ideas ?</p>
  
  <p>Thank you !</p>
