> Buildr does not work with JRuby's Ant integration. Since Antwrap hasn't been updated in almost three years, I tried to follow the JRuby + Ant examples in the article linked at the end. This simple script works using just jruby:
> # test.rb
> require 'ant' # Use JRuby Ant integration
> puts ant.properties['ant.version']
> puts ant.properties['ant.core.lib']
> But when I try accessing ant from Buildr, I keep getting a TypeError that complains about Ant not being a class. This buildfile:
> # buildfile - buildr sandbox
> VERSION_NUMBER = "1.0.0"
> GROUP = "buildr-sandbox"
> require 'ant'
> repositories.remote << "http://www.ibiblio.org/maven2/"
> desc "The Buildr-sandbox project"
> define "buildr-sandbox" do
>   project.version = VERSION_NUMBER
>   project.group = GROUP
>   package :jar
> end
> Results in this error:
> Buildr aborted!
> TypeError : Ant is not a class

> I think it's because $JRUBY_HOME/lib/ruby/site_ruby/shared/ant.rb defnes Ant as a class while lib/buildr/java/ant.rb, which runs first (I think) defines it as a module.
