Ant task with wildcard expansion for svn.

Ant is a popular tool among Java developers but one can use it for some other generic tasks. For example using svn as a task inside an ant script is provided by a library. However wildcard expansion won't work under this task. One way to over come this to use an exec task as follows (in windowz):

<exec executable="cmd.exe">
  <arg line=" /C svn --force delete pathtofiles\*.dat
             --username=username --password=password">
  </arg>
</exec>
