Package method having no effect in Buildr

Question

I'm trying to package a scala project into a jar and write properties to the Manifest using Buildrs package() method.

The package seems to have no affect on the Manifest. Here's the build file:

VERSION_NUMBER = "1.0.0"
GROUP = "Green"
COPYRIGHT = "Green CopyRight"

require 'buildr/scala'

Buildr::Scala::Scalac::REQUIRES.library = '2.8.0-SNAPSHOT'
Buildr::Scala::Scalac::REQUIRES.compiler = '2.8.0-SNAPSHOT'
Java.classpath.reject! { |c| c.to_s.index('scala') }
Java.classpath << Buildr::Scala::Scalac::REQUIRES

ENV['USE_FSC'] = 'yes'

repositories.remote << "http://www.ibiblio.org/maven2/"

desc "The Green project"
define "Green" do
    project.version = VERSION_NUMBER
    project.group = GROUP
    package(:jar).with :manifest=>manifest.merge(
        'Main-Class'=>'com.acme.Main',
        'Implementation-Vendor'=>COPYRIGHT
    )
end

And here's the resulting Manifest:

Build-By: brianheylin
Build-Jdk: 1.6.0_17
Implementation-Title: The Green project
Implementation-Version: 
Implementation-Vendor: 
Main-Class: green.GreenMain
Manifest-Version: 1.0
Created-By: Buildr

Notice that neither the Implementation-Vendor or Main-Class property has been overwritten. I run Buildr as follows:

jruby -S buildr clean package

I'm using jRuby 1.4.0 and Buildr 1.3.5 (installed as a gem). Anyone any ideas on why this is the case?

I can't reproduce this issue after the initial occurrence.
