I downloaded the 1.5 version of Jruby today, and was eager to try out
the
new Ant integration. I found Charles Nutter’s “Ivy and Ant” tutorial
(http://blog.headius.com/2010/04/using-ivy-with-jruby-15s-ant.html), and
tried running the Rakefile that downloads and installs Ivy. Here’s what
I
have in my Rakefile:
require ‘ant’
namespace :ivy do
ivy_install_version = ‘2.0.0-beta1’
ivy_jar_dir = ‘./ivy’
ivy_jar_file = “#{ivy_jar_dir}/ivy.jar”
task :download do
mkdir_p ivy_jar_dir
ant.get :src =>
“http://repo1.maven.org/maven2/org/apache/ivy/ivy/#{ivy_install_version}/ivy-#{ivy_install_version}.jar”,
:dest => ivy_jar_file,
:usetimestamp => true
end
task :install => :download do
ant.path :id => ‘ivy.lib.path’ do
fileset :dir => ivy_jar_dir, :includes => ‘*.jar’
end
ant.taskdef :resource => "org/apache/ivy/ant/antlib.xml",
#:uri => "antlib:org.apache.ivy.ant",
:classpathref => "ivy.lib.path"
end
end
I then tried executing the rakefile using the following commands:
c:> cd ivtytest
c:\ivytest> C:\td\apps\ruby-1.5.0\bin\jruby -S rake ivy:download
(in C:/td/apps/jruby-1.5.0/bin/test)
mkdir -p ./ivy

From what I can gather, it appears that I’m using the wrong version of
Ant. Here’s what’s in my classpath:
c:\td\apps\apache-ant-1.7.1\lib\ant.jar
…and here’s what I get for a version:
Apache Ant version 1.7.1 compiled on June 27 2008
Is the issue my version of Ant? If so, then what version should I use?
Thanks!
