Parser error reporting in jenkins-jobs is dismal

[Kevin L. Mitchell]

jenkins-jobs could use much better error reporting. I had set up a job template, and was trying to use a project to realize it. I had given the project a list of names. All I got from jenkins-jobs for processing this was an obscure exception about a list not being hashable; it took a significant amount of effort to isolate the root cause of the problem to the project's name.

Can you provide an example of the problematic config? Thanks!

This was more of a general complaint. Basically, the parsing problem I specifically noticed was with a construct such as this:

    - job-template:
        name: 'foo-{name}-bar'

    - project:
        name:
          - 'proj1'
          - 'proj2'
          - 'proj3'
        jobs:
          - 'foo-{name}-bar'

Yes, I'd really like to see a YAML validator like voluptuous in JJB.

Marking as a dupe since it's very similar to the other bug.
