[Grammatica-users] small problem: ant action always fires

[Edwin Olson]

Hi!

First off, grammatica is good stuff. I'm using it to build a matlab-like 
environment, since both octave and matlab have major issues as far as 
I'm concerned. :)

I'm working in pure java, and everything's going great, except for a 
small annoyance: anytime I invoke ant on my build.xml file, the 
grammatica task "fires" and regenerates its source code. It does this 
even if the grammar file has not changed, and even if I invoked 'ant 
clean' (the generated files are then promptly deleted.)

This isn't a show stopper, but it is fairly annoying. It's entirely 
possible I'm doing something wrong with my build.xml file, so I've 
attached it.

Thanks for any advice,

-Ed
