This is not Ants job.
You have to set up a Continous Build system like CruiseControl or Hudson.
These systems check against scm (subversion, cvs, ...) for updates and start a
build (Ant, Maven, ...).
Simplest solution would be an endless loop which starts the build. As Ant works
inkrementally on most tasks, folowing builds would be faster. You also could
tune that using <uptodate> and <available> in combination with
condition targets (<target if|unless>).
@echo off
cls
:loop
call ant
sleep 5m
goto loop
