ant script to get local revision number from the subversion's .svn/entries file

build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="svn" default="revision-number" basedir=".">

    <target name="check-svn-entries">
        <available file=".svn/entries" property="svn.entries.present"/>
    </target>
    
    <target name="revision-number" depends="check-svn-entries" if="svn.entries.present">
      <loadfile srcfile=".svn/entries" property="revision">
        <filterchain>
          <headfilter lines="1" skip="3"/>
        </filterchain>
      </loadfile>
      <echo file="REVISION" message="${revision}"/>
    </target>

</project>

This seems to not work any more with SVN 1.7, the file entries contains "12", but I have a revision around 400000...
