Re: Re: Java World: Build scripts with Groovy and Ant artcicle

I think being able to easily load properties files would be quite 
useful.  I do this all the time, both in ant scripts, and plain old 
programs.

I also like the way that ant does "in-file property expansion".  From 
the Ant doc on the property task:

        Example of entries in a .properties file:
                build.compiler=jikes
                deploy.server=lucky
                deploy.port=8080
                deploy.url=http://${deploy.server}:${deploy.port}/
