title: passing command line arguments to ant
body: <p>I am relatively new in ant, at school I have an assignment to do a build file. One of my questions is to copy to "/foldercopy" the file whose name(or path) is taken as argument for ant. I need to do something like:</p>
  
  <p>ant cpfile file.txt</p>
  
  <p>So ant will copy the file.txt to /foldercopy. I searched a lot on google but all I could find was something with "-Darg", but my teacher said that it's not correct. Is there any way to do it?</p>
