Executing partial job updates

[Ian Duffy]

Hi All,

I'm wanting to build up static helper functions that given a job they overlay some functionality.

I've started of at looking at using with example:

def job = job('some-name')

setGitRepoURL(job, "http://github.com/lalala.git")

setGitRepoBranch(job, "master")

def setGitRepoUrl(def job, def gitUrl) {

    job.with {

        scm {

            git {

                remote {

                    url(gitUrl)

                }

            }

        }

    }

}

def setGitRepoBranch(def job, def branchName) {

    job.with {

        scm {

            git {

                remote {

                    branch(branchName)

                }

            }

        }

    }

}

The result is setGitRepoBranch changes get in but setGitRepoURL changes do not. Is there any way to do a merge of the two?

Thanks,

Ian.

I understand that you want to limit duplication of those two methods - if so you can use 'delegate'

            ...
            publishers
            {
                addAuthorDescActions().each { action -> action(delegate) }
                ...
            }

    public List addAuthorDescActions()
    {
        [
            {
                context -> context.with
                {
                    groovyPostBuild
                    {
                        sandbox(true)
                        script(addAuthorDesc())
                    }
                }
            }
        ]
    }

Other way to limit duplication is groovy Map passed as arguments.

I'm not sure if you mean the same by 'overlay' functionality - I found useful to code complex pipelines with delegate + traits + Map and normal object programming. Complexity comes from number of projects and reporting we get from Jenkins - we put Jenkins not-related stuff into Ansible and call it from Jenkins anyway.

def setGit(Map args) {
    args.job.with {
        scm {
            git {
                remote {
                    if (args.branchName)
                    {
                        branch(args.branchName)
                    }
                    if (args.gitUrl)
                    {
                        url(args.gitUrl)
                    }                  
                }
            }
        }
    }
}
setGit(job: job, branchName: 'master')

The scm configuration is always replaced as a whole and can not be modified. You can only have one helper method to build the while scm config at once. Or you can to use a configure block to amend an existing config.

You can solve this problem by using a different approach 

Define a function called getGitRepository()

which returns an object with two parameters 

url and branch 

Your scm section will be as follows 

scm {

            git {

                remote {

                    url(getRepository().url)

                       branch(getRepository().branch)

                }

            }

        }

    }

Regards,

Z
