title: How to use Ant sources with Eclipse?
body: <p>my question relates to the Ant libs and source included with various Eclipse distributions. e.g.</p>
  
  <p><strong>eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145</strong> and
  <strong>eclipse/plugins/org.apache.ant.source_1.7.1.v20090120-1145.jar</strong></p>
  
  <p>How can I associate these together? What I'd like to do is set a breakpoint in the Ant Javac task, so I can confirm precisely which arguments are being passed to it. (This is proving very difficult to analyse from the build.xml itself due to a complicated structure with lots of imports and taskdefs).</p>
  
  <p>I can see no way to associate them within Preferences/Ant, and when adding the jar to my Ant launcher's classpath it seems to just ignore my breakpoints in it, no matter even if I put it higher on the classpath than "Ant Home (Default)" itself.</p>
  
  <p>I'm presumably missing something obvious, your answers are much appreciated.</p>
