I use the Batch Task plugin to run my releases, perform deployments (and just about anything else).

I have these tasks attached to the project (Jenkins Job), not separate Jobs.

The build pipeline would require me to separate out these tasks into their own jobs so that I can use it.

It would be a far more elegant solution (and stop an unnecessary proliferation of jobs) if the build pipeline plugin would support the Batch Plugin tasks of a Job.

Additional Information: The usage of the tasks attached to an exsting job is preferable, as that way we can make use of the existing workspace, and not have to check it out (and probably build it) multiple times unnecessarily.
