deleting a file if it does or does not exist

[Glen Marchesani]

Hello I have a newbie question,

I want to delete a file (part of my clean task) but the file isn't guaranteed to be 
there.  I currently use

  <delete file="generated.jar"/>    

This only works if the file does exist if it doesn't I get an error

"D:\foo\build.xml:295: Unable to delete file D:\foo\generated.jar"

As a work around I did this.
  
<delete>
       <fileset dir="." includes="**/generated.jar.*"/>
</delete>


I am looking to learn of better ways to do the file deletion if it exists and not fail 
if it doesn't.

regards,
Glen
