title: Creating ant build.xml files for each project in workspace
body: <p>How can I create an ANT file for multiple projects under the same workspace in Eclipse?</p>
  
  <p>Thought about using Jenkins, but Jenkins creates a single build.xml file using the Ant Emulator Plugin, within each project and does not give me the possibility to insert my keystore parameters directly at build time.</p>
  
  <p>The idea is that ultimately I want all my projects in my workspace signed using an automated tool.</p>
  
  <p>Thank you!</p>
