title: Ant Script (qnx.xml) fails while packaging BB10 build
body: <p>I have created an application for BB10 using IBM Worklight. The application version currently on production in v1.0. The application descriptor has version 1.0 for BB10.</p>
  
  <p>I want to promote a new build with version 1.1. But, before releasing the build, I want to create interim builds for testing. Ex: 1.001, 1.002 and so on.</p>
  
  <p>I am using antcontrib qnx.xml to package and sign blackberry 10 builds. When using this build process, the blackberry10 build fails stating: Native Packager exception occurred.</p>
  
  <p>Also, from Worklight perspective, the versions that we can provide is only in format x.y. We cannot have x.y.z as the version in the application descriptor.</p>
  
  <p>In such a situation, how do I fix this issue of releasing interim builds with version 1.001, 1.002 and then release the final build 1.1?</p>
