My target for deleteing files doesn't do anything:

<target name="deletestuff">
  <delete verbose="true" >
    <dirset dir="..\..\..\" excludes="SSC main build"/>
  </delete>
</target>

When I run this nothing gets deleted. I am trying to delete everything from a folder relative to my basedir "SSC/main/build" excluding the path to the ant build file. What am I doing wrong?

Thanks, Dave
