Using buildr artifact download from ruby

[Carlos Sanchez <ca...@apache.org>]

Hi,

I was wondering if buildr could be used to download artifacts from a
Maven repository from any ruby script. I need to download them using
ruby and thought about giving a try to buildr before going for jruby
or something more complicated.

Something along the lines of

require 'rubygems'
require 'buildr'

artifact('org.apache.openjpa:openjpa:jar:1.2.1').invoke


which of course doesn't work.

Any suggestions?

Thanks

If you don't mind a little hack, the following works on recent versions of
buildr:

require 'rubygems'
require 'buildr'

class << Buildr.application
  def rakefile; __FILE__; end
end

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

artifact('org.apache.openjpa:openjpa:jar:1.2.1').invoke

I think it was possible to use buildr as a library without this little hack
at some point... and I wouldn't mind explicitly supporting this since it's
pretty convenient to do things outside the scope of a buildfile for certain
use-case.
