可以在Azure管道中完成条件变量分配吗?

问题描述

Azure管道具有表达式和条件，但是我找不到办法将两个值之一分配给变量，具体取决于条件.

Azure Pipelines has Expressions and Conditions, but I can find no way to assign one of two values to a variable, based on a condition.

有什么办法可以完成这个伪代码吗?

Is there any way to accomplish what this pseudo-code would?

    ${{ if endsWith( variables['Build.SourceBranchName'], '/master' ) }}:
      buildVersion: variables['mavenVersion']
    ${{ else }}:
      buildVersion: variables['Build.SourceBranchName']

推荐答案

这应该可以解决问题....

This should do the trick....

BuildVersion初始化为$(Build.SourceBranch)如果是主分支，则将其更改为$(mavenVersion)否则没有变化.

BuildVersion is initialised as $(Build.SourceBranch)if it's the master branch you change that to the $(mavenVersion)else no change.

variables:
  mavenVersion: '1.0'
  buildVersion: $(Build.SourceBranch)

pool:
  vmImage: 'ubuntu-latest'

steps:

- script: echo '##vso[task.setvariable variable=buildVersion]$(mavenVersion)'
  displayName: "Set the buildVersion as mavenVersion if the Build.SourceBranch = 'refs/heads/master' "
  condition: eq(variables['Build.SourceBranch'], 'refs/heads/master')

- script: echo $(buildVersion)
  displayName: 'Printing the variable'

非主分支打印'refs/heads/branch_name'，即mavenVersion

non-master branches prints 'refs/heads/branch_name' which is mavenVersion

master分支打印1.0，即mavenVersion

master branch prints 1.0 which is mavenVersion
