title: How do i pass parameters from Jenkins to Ant scripts?
body: <p>For some GUI testing I'm creating a Jenkins task for each GUI module to be tested.
  Once created I'm using Ant to build these tests, but I'm not aware of how to actually pass parameters from Jenkins to Ant build file? Basically how do I do variable substitution in Ant?</p>
  
  <p>I'm using the Sahi framework to test GUI components, so the flow goes like this...</p>
  
  <p>Jenkins &rarr; Ant build script &rarr; Sahi file to execute</p>
  
  <p>Can anyone please take a look at it?</p>
