Alert: Properties aren't variable. They're immutable. Their value does
not change once set.

More properties here. It's the same Perl script invocation each time
around. That's probably not what you intend to do.
There are a couple simple things you can do to find out what's going on.
ant -h # help
ant -v # verbose, some info
ant -d # debug, including properties getting set
ant -diagnostics # also useful to know what info is available here
Take a look at the <listproperties> task, also occasionally useful to
produce diagnostic output.
