通过多个作业下载相同的管道工件LatestFromBranch

问题描述

我目前正在编写一个Azure管道YAML，它可以下载最新的开发工件并在不同的环境中执行不同的测试.

I currently write a Azure pipeline YAML which downloads the latest development artifacts and executes different tests in different environments.

由于每种测试都被建模为自己的作业，因此作业的第一步是下载工件(文档).

Since every kind of test is modeled as its own Job, the first step of the job is downloading the artifact (documentation).

- task: DownloadPipelineArtifact@2
  inputs:
    buildType: 'specific'
    project: '[hidden]'
    definition: '[hidden]'
    buildVersionToDownload: 'latestFromBranch'
    branchName: 'refs/heads/development'

如果在管道运行期间创建了新的产品，我如何实现每个作业都具有相同的工件?

How can I achieve that every job takes the same artifact, also if a newer is created during the pipeline run?

我的第一种方法是下载最新的工件并提取具体版本.但是我无法获得pipelineId所需要的内部版本ID，以下载特定版本.

My first approach was downloading the latest artifact and extracting the concrete version. But I wasn't able to get the build id which is required as pipelineId for downloading a specific version.

推荐答案

我实现了@ LeoLiu-MSFT建议的解决方案.

I implemented a solution as suggested by @LeoLiu-MSFT.

1. 找到最后一个成功的主版本并存储buildId
2. 以buildId作为参数提供下载任务
3. 在所有测试作业中使用下载任务

1. Find the last successful master build and store the buildId
2. Provide a download task with the buildId as parameter
3. Use the download task in all test jobs

以下摘录显示了一个具体示例.

The following snippets show a concrete example.

# 1. steps/find-latest-build.yml
steps:
  - task: Bash@3
    name: LatestArtifactsBuild
    displayName: 'Find latest successful master build'
    env:
      system_accesstoken: $(System.AccessToken)
    inputs:
      targetType: 'inline'
      script: |
        definitionId=<pipeline>
        url="https://dev.azure.com/<organization>/<project>/_apis/build/builds?api-version=5.1"
        url+="&definitions=$definitionId"
        url+="&resultFilter=succeeded"
        url+="&branchName=refs/heads/master"
        url+="&\$top=1"

        json=$(curl -sL -H "Authorization: Bearer $system_accesstoken" -H 'Content-Type: application/json' $url)
        buildId="$(echo $json | jq '.value[0].id' )"

        echo "##vso[task.setvariable variable=id;isOutput=true]$buildId"

# 2. steps/download-artifacts-from-pipeline-build.yml
parameters:
  definitionId: <pipeline>
  buildId: $(Build.BuildId)
  artifactName: ''

steps:
  - task: DownloadPipelineArtifact@2
    displayName: 'Download build artifact archives'
    inputs:
      buildType: 'specific'
      project: $(System.TeamProjectId)
      definition: ${{ parameters.definitionId }}
      buildVersionToDownload: 'specific'
      pipelineId: ${{ parameters.buildId }}
      artifactName: ${{ parameters.artifactName }}

# 3. examples/reuse-build-artifacts.yml
trigger: none

jobs:
  - job: PrepareBuild
    displayName: 'Provide build information'
    steps:
    - checkout: none
    - template: ../steps/find-latest-build.yml

  - job: DownloadAllArchivesOfSpecificBuild
    dependsOn: PrepareBuild
    variables:
      download_build_id: $[ dependencies.PrepareBuild.outputs['LatestArtifactsBuild.id'] ]
    steps:
    - checkout: none
    - template: ../steps/download-artifacts-from-pipeline-build.yml
      parameters:
        buildId: $(download_build_id)
