Problem using build.yaml to specify groups of dependencies

[Russ Teabeault]

I am trying to use buildr.yaml to specify my dependencies

artifacts:
  compile:
    - ant:ant:jar:1.6.5
    - ant-contrib:ant-contrib:jar:1.0b2
    - ...

Based on everything I have read I should then be able to do

compile.with artifact_ns[:compile]

However, this fails in the artifacts method of artifact.rb since each spec
in the array is an ArtifactRequirement and there is no case handling that
type.

Is this a bug?  Is there a better way to do this?  What are other people
doing?

Thanks,
