[buildr] How to debug?

Hi,

I want to debug (i.e., run step-by-step) buildr, but it seems I'm
missing something important. Will you tell me how to do it?

Here's what I tried.

<code>
require 'rubygems'
load File.join(File.dirname(__FILE__), '../../lib/buildr.rb')

load File.join(File.dirname(__FILE__), 'buildfile')

task('simple_java_project:package').invoke
</code>

Although I can step through the Project.define method when 'buildfile'
is loaded, nothing happens afterwards. The jar package is not created.

Regards.

Lacton

Thanks Assaf. 'Buildr.application.run' was exactly what I needed. Now,
it works like a charm.

Have a nice day.

I didn't use it myself, but if you want true step-by-step and breakpoints,
you can try ruby-debug:
http://rubyforge.org/projects/ruby-debug/

Then just add:

  require 'ruby-debug' ; Debugger.start

at the top of the buildfile, and call debugger whenever you want a
breakpoint.
