[SOLVED] Devops YAML - set build name using expression

Devops YAML - set build name using expression

In a yaml build, is it possible to set the build name using an expression; it would be advantageous if I could match the release pipeline with the actual build id.

Example:

trigger:  
- master

variables:  
    major: 2  
    minor: 3  
    offset: 2000  
    bid: $[$build.BuildID -as [int] + $offset]

name: "$(major).$(minor).$(bid)"

Solution

You can use the UpdateBuildNumber command to dynamically set the name as part of a bash or PowerShell script.

For more details you can see this blog post, but the gist of it is something like this:

name: 'Set dynamically below in a task'

variables:  
    major: 2  
    minor: 3  
    offset: 2000

steps:
- task: PowerShell@2
  displayName: Set the name of the build (i.e. the Build.BuildNumber)
  inputs:
    targetType: 'inline'
    script: |
      [int] $buildIdWithOffset = ([int] $(Build.BuildId)) + ([int] $(offset))
      [string] $buildName = "$(major).$(minor).$buildIdWithOffset"
      Write-Host "Setting the name of the build to '$buildName'."
      Write-Host "##vso[build.updatebuildnumber]$buildName"
