Cannot set Git executable using Job DSL

[shaneoh1980 McP]

I'm converting all of our Jenkins jobs to DSL scripts and I've come accross one where we use a Git executable other than the "default" one. 

I've spent two days trying to get this to work and no matter what I do it just won't work. I need this in the config.xml which gets generated for the job ("Ubuntu Git" is the name of one of our Git installations which is configured as a tool for the Jenkins server):

<gitTool>Ubuntu Git</gitTool>

But no matter what I do I always end up with:

<gitTool>default</gitTool>

It doesn't seem to be supported by the DSL so I have been using the configure block. I've tried hundreds of ways but the way I most expected to work is below. Note that I am new to using the configure block. This is starting to drive me spare - does anyone know what is wrong in this configure block that I have? Or, am I somehow missing that this is actually natively supported by the job dsl?

job('job') {
  scm {
    git {
      remote {
        url('https://github.com/mygithub/project.git')
        credentials('25dwere85ds-dgh6-5874-6954-e226asdasd07e7')
        branches('*/my_branch')

       configure { project ->
         project << 'hudson.plugins.git.GitSCM' {
           paramDefs << 'gitTool' {
             string('Ubuntu Git')
               }
            }
         }
      }
   }
}

I would appreciate any advice.

You need to configure in “job” block not “git” block like :

 

job(‘job’) {

  scm {

    git {

     …

    } //git

  } //scm

 

  configure { project ->

                project / scm(class: ‘hudson.plugins.git.GitSCM’) {

                                gitTool ‘Ubuntu Git’

                } //project

} //configure

} //job

Thanks - but that generates a separate block of XML, with what I want, but it doesn't apply it to the git scm and therefore has no effect on the job.  In other words, inside the XML for git, I still see:

<gitTool>Default</gitTool>

But then outside that, in a separate block, I see:

    <scm(class: ‘hudson.plugins.git.GitSCM’)>
        <gitTool>Ubuntu Git</gitTool>
    </scm(class: ‘hudson.plugins.git.GitSCM’)>
</project>

I should add that if I create a job using this as a seed job, the default option is still selected.

This one works correctly (put configure block inside git block).

 

    scm {

        git {

            remote {

                ..

            }

             configure { node ->

                                node / gitTool << 'Ubuntu Git'

             }

         }

   …

Thank you! That worked. Thanks a lot for your help.
