copy aritfacts between builds with build flow plugin

[Åsmund Østvold]

I am investigating the build flow plugin and have hit a issue I am not able
to solve.  What I want to able to copy artifacts from build job to test
jobs:

buildJob = build("buildBinaries")

parallel(
    { build("test1") },
    { build("test2") }
)

All projects need to be able to run concurrently(they are configured with
different work spaces) including the build flow project.

Have anybody been able to do this?
