Enable Ant using JRuby's Ant integration
----------------------------------------
Key: BUILDR-567
URL: https://issues.apache.org/jira/browse/BUILDR-567
Project: Buildr
Issue Type: Improvement
Components: JRuby
Affects Versions: 1.4.4
Reporter: David
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!

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.
