title: Why are my svn ant tasks failing?
body: <p>I am trying to run a build script and I keep getting errors during a specific svn task. When I  try to build the target from the command line, I get an authentication error. When I run the build from flex builder I get an error saying "please get a newer Subversion client". From what I can tell there is a root issue that can be seen here when doing an ant -verbose:</p>
  
  <pre><code>svn_update:
      [echo] Updating the project source...
       [svn] Using javahl
       [svn] &lt;Update&gt; started ...

       [svn] At revision 373.

  <p>As you can see, the second (failing) svn_update target is using command line, and the first (working) update is using javahl. I am using the default attributes for svn, so javahl should default to be used. </p>
  
  <p>I updated my svnant jars to 1.3.0.</p>
  
  <p>Would love some help with this one!</p>
