title: How to get system user in ant (within eclipse)?
body: <p>How can I access the name of the system user (which eclipse also uses for the javadoc 
  author tag) in my ant build file?</p>
  
  <p>I'm trying to show some information about the current program version in my java application.
  I decided to use <a href="http://jreleaseinfo.sourceforge.net/" rel="noreferrer">jreleaseinfo</a> which passes variables from my ant build script to my java classes (to show them in a window). With <a href="http://subclipse.tigris.org/svnant.html" rel="noreferrer">svnant</a> I'm even capable of accessing the latest revision number and build date from svn within my build.xml.</p>
  
  <p>Now: The last thing I need is to show who made that build!</p>
