如何在同一configure块中追加到Jenkins job dsl创建的节点?

我有一些看起来像这样的jobDsl:

multibranchPipelineJob('foo/bar') {
        branchSources {
        git {
            remote('https://github.com/jenkinsci/job-dsl-plugin.git')
            credentialsId('github-ci')
            includes('JENKINS-*')
        }
    }
}

生成以下xml(代码段):

<!-- 1. foo/bar -->
<org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject>
    <sources class='jenkins.branch.MultiBranchProject$BranchSourceList'>
        <data>
            <jenkins.branch.BranchSource>
                <source class='jenkins.plugins.git.GitSCMSource'>
                    <id>d45cd641-7223-4b58-9de5-837c3fe584a7</id>
                    <remote>https://github.com/jenkinsci/job-dsl-plugin.git</remote>
                    <credentialsId>github-ci</credentialsId>
                    <includes>JENKINS-*</includes>
                    <excludes></excludes>
                    <ignoreOnPushNotifications>false</ignoreOnPushNotifications>
                </source>
                <strategy class='jenkins.branch.DefaultBranchPropertyStrategy'>
                    <properties class='empty-list'></properties>
                </strategy>
            </jenkins.branch.BranchSource>
        </data>
        <owner class='org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject' reference='../..'></owner>
    </sources>

我想做的就是通过configure块将一个节点(称为traits)附加到jobDsl multibranchJob api创建的jenkins.branch.BranchSource节点上:

multibranchPipelineJob('foo/bar') {
        branchSources {
        git {
            remote('https://github.com/jenkinsci/job-dsl-plugin.git')
            credentialsId('github-ci')
            includes('JENKINS-*')
        }

            configure {
               def first =  it / 'sources'(class: 'jenkins.branch.MultiBranchProject$BranchSourceList') / 'data' / 'jenkins.branch.BranchSource'
                first << traits {
                    foo('bar')
                }
            }
    }
}

但是,根据https://job-dsl.herokuapp.com/,上述dsl会这样创建xml:

<sources class='jenkins.branch.MultiBranchProject$BranchSourceList'>
    <data>
        <jenkins.branch.BranchSource>
            <traits>
                <foo>bar</foo>
            </traits>
        </jenkins.branch.BranchSource>
        <jenkins.branch.BranchSource>
            <source class='jenkins.plugins.git.GitSCMSource'>
                <id>7fd47865-fffa-4f8f-98f1-ac6de65249f7</id>
                <remote>https://github.com/jenkinsci/job-dsl-plugin.git</remote>
                <credentialsId>github-ci</credentialsId>
                <includes>JENKINS-*</includes>
                <excludes></excludes>
                <ignoreOnPushNotifications>false</ignoreOnPushNotifications>
            </source>
            <strategy class='jenkins.branch.DefaultBranchPropertyStrategy'>
                <properties class='empty-list'></properties>
            </strategy>
        </jenkins.branch.BranchSource>
    </data>
</sources>

基本上,是否有任何方法可以附加到通过BranchSource调用创建的branchSources节点上?

参加聚会有点晚,但遇到了同样的问题,这让我发疯...看起来将配置块移动到管道定义的末尾会有所帮助 - 也使用正确的 XPath 工具。

Fred 的博文让我找到了正确的方向。去看看:https://ftclausen.github.io/infra/jenkins/jenkins-jobdsl-git-traits/

管道定义

multibranchPipelineJob('foo/bar') {
        branchSources {
        git {
            id("foobar")
            remote('https://github.com/jenkinsci/job-dsl-plugin.git')
            credentialsId('github-ci')
            includes('JENKINS-*')
        } 
    }
    configure {
        def traits = it / sources / data / 'jenkins.branch.BranchSource' / source / traits {
            traits << 'jenkins.plugins.git.traits.LocalBranchTrait'{}
        }
   }
}

结果 config.xml

<sources class='jenkins.branch.MultiBranchProject$BranchSourceList'>
        <data>
            <jenkins.branch.BranchSource>
                <source class='jenkins.plugins.git.GitSCMSource'>
                    <id>foobar</id>
                    <remote>https://github.com/jenkinsci/job-dsl-plugin.git</remote>
                    <credentialsId>github-ci</credentialsId>
                    <includes>JENKINS-*</includes>
                    <excludes></excludes>
                    <ignoreOnPushNotifications>false</ignoreOnPushNotifications>
                    <traits>
                        <jenkins.plugins.git.traits.LocalBranchTrait></jenkins.plugins.git.traits.LocalBranchTrait>
                    </traits>
                </source>
                <strategy class='jenkins.branch.DefaultBranchPropertyStrategy'>
                    <properties class='empty-list'></properties>
                </strategy>
            </jenkins.branch.BranchSource>
        </data>
        <owner class='org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject' reference='../..'></owner>
    </sources>

问题在于configure上下文中没有branchSources方法。因此,将调用外部上下文中的configure方法。在这种情况下,来自multibranchPipelineJob上下文。由于branchSources方法在调用configure方法时尚未完成,因此尚未生成任何分支源节点,因此configure块将创建一个新节点。

尝试以下方法:

multibranchPipelineJob('foo/bar') {
  branchSources {
    git {
      remote('https://github.com/jenkinsci/job-dsl-plugin.git')
      credentialsId('github-ci')
      includes('JENKINS-*')
    }
  }
  configure {
    def source =  it / 'sources'(class: 'jenkins.branch.MultiBranchProject$BranchSourceList') / 'data' / 'jenkins.branch.BranchSource'
    source << traits {
      foo('bar')
    }
  }
}
