title: How can I allow an Ant property file to override the value set in another?
body: <p>I have an ant file that does the following:</p>
  
  <pre><code>&lt;property file="project.properties" description="Project configuration properties"/&gt;
  &lt;property file="build-defaults.properties" description="default build configuration."/&gt;
  &lt;property file="build.properties" description="local build configuration overrides"/&gt;
  </code></pre>
  
  <p>I want to have defaults set in build-defaults.properties (which is checked in to SCM) but allow developers to override values in a local build.properties so that they can work with local paths.</p>
  
  <p>The problem is, it doesn't seem to be working; I've set this up, created an override in build.properties, but the value of my path remains the one set in build-defaults.properties. How do I accomplish this?</p>
