Configuring Git via a Configure block

[Misty Stanley-Jones]

Our Jenkins server's version of the Job DSL Plugin is a bit old, and I don't seem to be able to use the Github SCM commands directly. I need to set the name, URL, refspec, branch, and local branch. I've almost got the DSL correct, but it does not like me trying to specify the URL via a configure block. Here is what I have for my scm {} block:

def Repository = "https://my-git-server.com/my-user/repository.git"
def Branch = "master"

...

scm {
  configure { scm ->
    scm / UserRemoteConfigs / 'hudson.plugins.git.UserRemoteConfig' {
      name "origin"
      url "${Repository}"
      refspec "+refs/heads/${Branch}:refs/remotes/origin/${Branch}"
    }
    scm / branches / 'hudson.plugins.git.BranchSpec' {
      name "origin/${Branch}"
    }
    scm {
      localBranch "${Branch}"
    }
  }
}

I have a feeling the localBranch setting is wrong but I can't figure out how to do it. If I leave it in, I get this error:

groovy.lang.MissingMethodException: No signature of method: groovy.util.Node.call() is applicable for argument types: (script14292399124951505156629$_run_closure1_closure2_closure5_closure8) values: [script14292399124951505156629$_run_closure1_closure2_closure5_closure8@579ab801]

    at javaposse.jobdsl.dsl.WithXmlAction.execute(WithXmlAction.groovy:17)
    at javaposse.jobdsl.dsl.WithXmlAction$execute$0.call(Unknown Source)

If I take it out, I get this error:

groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method groovy.util.Node#leftShift.
Cannot resolve which method to invoke for [null] due to overlapping prototypes between:
    [class groovy.util.Node]
    [class java.lang.String]

I suspect the problem is a conflict in the 'name' parameter, or else I am just confused about how to do this.
Here is the XML on a job that is configured correctly:

<scm class="hudson.plugins.git.GitSCM" plugin="g...@1.1.22-SNAPSHOT">
  <configVersion>2</configVersion>
  <userRemoteConfigs>
    <hudson.plugins.git.UserRemoteConfig>
      <name>origin</name>
      <refspec>+refs/heads/master:refs/remotes/origin/master</refspec>
      <url>https://my-git-server.com/my-user/repository.git"</url>
    </hudson.plugins.git.UserRemoteConfig>
  </userRemoteConfigs>
  <branches>
    <hudson.plugins.git.BranchSpec>
      <name>origin/master</name>
    </hudson.plugins.git.BranchSpec>
  </branches>
  <localBranch>master</localBranch>
 ... omitted default and empty values ...
  <browser class="hudson.plugins.git.browser.GithubWeb">
    <url>https://my-git-server.com/my-user/repository.git</url>
  </browser>
... omitted default and empty values ...
</scm>

Thanks in advance for any help you can provide!

I got everything to work except the Git remote name, which seems to clash with the job name and actually renames the job. So I gave up for now.
