title: Ant build error = exec-shell returned:1
body: <p>I am doing one demo project in Kony Studio. While running application for Android, I always getting <code>Ant build error</code>. </p>
  
  <p>Please check the error log,</p>
  
  <pre><code>-post-package:
  [exec-shell] 
  [exec-shell] /Users/mac/Library/Android/sdk/tools/ant/build.xml:1037: The following error occurred while executing this line:-do-debug:

  </code></pre>
  
  <p>Log says there is a permission issue with file, but I gave both read/write permission, even no luck and I am using <code>MacBookPro</code>. Help me to come out from this issue. Thanks in advance. </p>
