在 Azure DevOps yml 中获取日期时间并与之连接版本号答案

【问题标题】：Getting date time in Azure DevOps yml and concat a version number with it在 Azure DevOps yml 中获取日期时间并与之连接版本号

【问题描述】：

我有以下 yml。我试图做的是根据其他几个变量（version.Major、version.Minor、versionDay 和BuildNumber）创建一个版本号。但是设置变量 powershell 任务不会覆盖 versionday 的初始值，因此下面我的 echo 脚本中 versionNumber 的输出将类似于：1.0.set below.2021037.6 有什么想法吗？我没有看到语法问题？

trigger:
  branches:
    include:
      - develop, 
      - sprint/*
      - Sprint/*

pool:
  name: 'MyCustomAgent'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  version.Major: '1'
  version.Minor: '0',
  versionDay: 'set below'
  versionNumber: 'set dynamically'

steps:
- script: |
    echo: $(Build.SourceBranch)

- powershell: |
      if ("$(Build.SourceBranch)".Contains('sprint')) {
        Write-Host "##vso[task.setvariable variable=buildConfiguration;]Release"
        [string] $currentMonthDay= (Get-Date -Format 'MMdd')
        Write-Host "##vso[task.setvariable variable=versionDay]$currentMonthDay"
        Write-Host "##vso[task.setvariable variable=versionNumber]$(version.Major).$(version.Minor).$(versionDay)"

      } else {
        Write-Host "##vso[task.setvariable variable=buildConfiguration;]Debug"
        [string] $currentMonthDay= (Get-Date -Format 'MMdd')
        Write-Host "##vso[task.setvariable variable=versionDay]$currentMonthDay"
        Write-Host "##vso[task.setvariable variable=versionNumber]$(version.Major).$(version.Minor).$(versionDay).$(Build.BuildNumber)"
      }      

- script: | 
    echo building configuration $(buildConfiguration)
    echo $(versionDay)
    echo $(versionNumber)

【解决方案1】：

您需要将变量设置为输出 - 请注意以下 setvariable 语句的更改：

pool:
  name: 'MyCustomAgent'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  version.Major: '1'
  version.Minor: '0',
  versionDay: 'set below'
  versionNumber: 'set dynamically'

steps:
- script: |
    echo: $(Build.SourceBranch)

- powershell: |
      # note the use of ;isOutput=true in setvariable commands
      if ("$(Build.SourceBranch)".Contains('sprint')) {
        Write-Host "##vso[task.setvariable variable=buildConfiguration;]Release"
        [string] $currentMonthDay= (Get-Date -Format 'MMdd')
        Write-Host "##vso[task.setvariable variable=versionDay]$currentMonthDay"
        # You can't use $(versionDay) here as setvariable is for subsequent steps/jobs/stages
        # use its calculated value instead
        Write-Host "##vso[task.setvariable variable=versionNumber]$(version.Major).$(version.Minor).$($currentMonthDay)"

      } else {
        Write-Host "##vso[task.setvariable variable=buildConfiguration;isOutput=true]Debug"
        [string] $currentMonthDay= (Get-Date -Format 'MMdd')
        Write-Host "##vso[task.setvariable variable=versionDay;isOutput=true]$currentMonthDay"
        # You can't use $(versionDay) here as setvariable is for subsequent steps/jobs/stages
        # use its calculated value instead
        Write-Host "##vso[task.setvariable variable=versionNumber;isOutput=true]$(version.Major).$(version.Minor).$($currentMonthDay).$(Build.BuildNumber)"
      }      

- script: | 
    echo building configuration $(buildConfiguration)
    echo $(versionDay)
    echo $(versionNumber)
