Setting up a development environment for Buildr plugin

Prerequisites:

• Install git.
• Install ruby, rubygems, and the braid gem.

Basic setup:

• Create a new folder and cd to it. To create the minimal skeleton for your GEM
• run git init && touch README && git add README && git commit -m "initial commit"
• run braid add git://git.apache.org/buildr.git --branch trunk buildr
• run ln -s buildr/rakelib rakelib
• Create your .gemspec file.
• Then copy buildr/Rakefile to Rakefile, and replace the reference to buildr.gemspec to your .gemspec.
• Create your structure: a lib, a spec folder.
• run echo "_reports" >> .gitignore

Specs setup:

• Create spec/spec_helpers.rb
• Paste this code in it:

unless defined?(SpecHelpers)
  module SandboxHook

    def SandboxHook.included(spec_helpers)
      # For testing we use the gem requirements specified on the buildr4osgi.gemspec
      spec = Gem::Specification.load(File.expand_path('../my.gemspec', File.dirname(__FILE__)))
      spec.dependencies.each { |dep| gem dep.name, dep.requirement.to_s }
      # Make sure to load from these paths first, we don't want to load any
      # code from Gem library.
      $LOAD_PATH.unshift File.expand_path('../lib', File.dirname(__FILE__))
      require 'mymodule'
    end
  end
  require File.join(File.dirname(__FILE__), "/../buildr/spec/spec_helpers.rb")

end

You're done.

Try rake -T to see the buildr tasks available, use rake coverage to run tests and rake failed when you need to insist.
