我目前正在使用Build Flow插件，该插件似乎已被 Jenkins 2.0 中的 Pipelines 所取代。

使用新管道重新构建我们现有的工作时遇到了一些问题。

目前，我有类似这样的代码：

ignore(FAILURE) {
  join = parallel([
    job1: {build('job1')},
    job2: {build('job2')},
    job3: {build('job3')}
  ])
}
results = [join.job1.result.toString(), join.job2.result.toString(), join.job2.result.toString()]

if(join.job1.result.toString() == 'SUCCESS') {
  buildList << join.job1.lastBuild.getDisplayName()
}

这里的目标是并行运行多个现有作业，然后访问有关已完成构建的信息。这在 Build Flow 插件中一直没有问题。

我一直找不到使用新管道访问这些数据的方法。

echo 'Checking streams for latest builds'
join = [:] 

join['Job1'] = { build job: 'Job1', parameters: [[$class: 'StringParameterValue', name: 'TimeWindow', value: '1200']], propagate: false} 
join['Job2'] = { build job: 'Job2', parameters: [[$class: 'StringParameterValue', name: 'TimeWindow', value: '1200']], propagate: false} 
join['Job3'] = { build job: 'Job3', parameters: [[$class: 'StringParameterValue', name: 'TimeWindow', value: '1200']], propagate: false}

parallel join

join['Job1'] 的转储不会像 Build Flow 插件那样提供对 AbstractBuild 或类似的访问权限。相反，它显示：

<org.jenkinsci.plugins.workflow.cps.CpsClosure2@2eac6ed9
def=com.cloudbees.groovy.cps.impl.CpsClosureDef@59647704
delegate=WorkflowScript@3aa1807f 
owner=WorkflowScript@3aa1807f
thisObject=WorkflowScript@3aa1807f 
resolveStrategy=0 
directive=0
parameterTypes=null 
maximumNumberOfParameters=0 
bcw=null>

使用新的管道，有没有办法访问像 job1.result、job1.lastBuild、job1.lastBuild.getDisplayName() 这样的数据？

有点晚了，但您也可以在闭包中定义命令runWrapper返回的对象build，并将其放置在parallel命令之外定义的映射中。

这是一个例子。注意：我正在使用propagate: false以便不引发异常（JUnit 测试失败等）。您必须决定如何处理异常、try/catch/finally 等。

要执行的示例管道作业（需要使用字符串 param 进行参数化commandStr）：

env.PASSED_CMD="${params.commandStr}"
stage('command-exec') {
    node {
        sh "${commandStr}"
    }
}

执行作业（配置）：

buildRuns = [:]
buildResults = [:]
def buildClosure(String jobKey, String paramAValue) {
    return {
        def runWrapper = build(
            job: 'command-test-job',
            propagate: false,
            parameters: [[$class: 'StringParameterValue', name: 'commandStr', value: paramAValue]]
        )
        buildResults."$jobKey" = runWrapper
    }
}
buildRuns."job1" = buildClosure("job1", "echo 'HI' && exit 0")
buildRuns."job2" = buildClosure("job2", "echo 'HO' && exit 0")
parallel buildRuns
for(k in buildRuns.keySet()) {
    def runResult = buildResults."$k"
    echo "$k -> ${runResult.result}"
    echo "$k -> ${runResult.buildVariables.PASSED_CMD}"
}

构建日志显示：

[Pipeline] parallel
[Pipeline] [job1] { (Branch: job1)
[Pipeline] [job2] { (Branch: job2)
[Pipeline] [job1] build (Building command-test-job)
[job1] Scheduling project: command-test-job
[Pipeline] [job2] build (Building command-test-job)
[job2] Scheduling project: command-test-job
[job1] Starting building: command-test-job #7
[job2] Starting building: command-test-job #8
[Pipeline] [job2] }
[Pipeline] [job1] }
[Pipeline] // parallel
[Pipeline] echo
job1 -> SUCCESS
[Pipeline] echo
job1 -> echo 'HI' && exit 0
[Pipeline] echo
job2 -> SUCCESS
[Pipeline] echo
job2 -> echo 'HO' && exit 0
[Pipeline] End of Pipeline

这与Steve-B 的 Answer非常相似，但您实际上不需要明确定义 runwrapper 或事先将其放置在附加映射中。

tl; dr您可以将并行构建存储到 hashMap 并通过直接循环它的 keySet 来访问该映射

对这个答案持保留态度，我使用的是旧版本的管道（Jenkins 2.7.2 和 Pipeline 2.2）。

您可以将并行构建结果存储到 hashMap 并遍历映射的 keySet 以获取有关构建的一些信息。

def create_build_job(job_name, pool_label="master", propagate=false) {
  build job: job_name, parameters: [[$class: 'LabelParameterValue', name: "node_label", label: "${pool_label}"]], propagate: propagate, wait:true
}

def buildmap = [:]
def build_results

stage 'Perform Build'
    //test1 is set to fail, test2 is set to succeed
    buildmap['test1'] = {create_build_job('test1', "your_node_label")}
    buildmap['test2'] = {create_build_job('test2', "your_node_label")}

    build_results = parallel buildmap

    for(k in build_results.keySet()){
      println build_results["${k}"].getProperties()
    }

对于这个管道，我只是将 RunWrapper 的所有属性转储在 map 中的 item 中，但是您可以直接访问每个属性，因此如果您想要构建的结果，您可以这样做：

build_results["${k}"].result

此管道生成的控制台输出（任何潜在的识别信息已编辑）是：

Started by user <user>
[Pipeline] stage (Perform Build)
Entering stage Perform Build

[Pipeline] [test1] { (Branch: test1)

您可以在以下步骤后使用 Jenkins API 访问该数据parallel：

Jenkins.instance.getItemByFullName('Job1').lastBuild
