Change Variable values based on branch in AzureDevOps CI Pipeline

Question

In AzureDevOps How to change the value of the variable based on the branch the CI pipeline is running for.

Like for dev branch var-value = "develop" where as for master branch var-value = "master".

Answer 1

You can use a simple PowerShell script that checks the pre-defined variable Build.SourceBranchName and set the variable value:

$branch = "$(Build.SourceBranchName)"
if($branch -eq "master")
{
    Write-Host "##vso[task.setvariable variable=var-value]master"
}
else
{
    Write-Host "##vso[task.setvariable variable=var-value]develop"
}
