title: Variables in PDE map files
body: <p>Some PDE builds use map files. In my case, the project is BIRT and the map files contains things like:</p>
  
  <pre><code>plugin@org.eclipse.birt.chart.device.extension=r262_v20110127,:ext:xgu@dev.eclipse.org:/cvsroot/birt,,source/org.eclipse.birt.chart.device.extension
  plugin@org.apache.batik.svggen.source,1.6.0=GET,http://build-birt/software/platform/orbit-S20100519200754-Helios/bundles/org.apache.batik.svggen.source_1.6.0.v200805290154.jar,usetimestamp=true
  </code></pre>
  
  <p>The problems are ":ext:xgu" and "http://build-birt/"</p>
  
  <p>I'm not xgu (I don't even have SSH access to the BIRT repo) and my DNS can't resolve "build-birt".</p>
  
  <p>How can this be solved? Is there an ANT task in the PDE build where I can replace Strings in map files before Ant tries to fetch resources? Or is it possible to use variables in map files?</p>
