Pass build variables to powerhshell inline script in Azure DevOps

To get the build variables with inline power shell script, you can try to use following syntax $env:variable:

$env:myvariable

The build variable:

The build result:

Note:At this moment, the value of nested variables (like $(myvariable$(Build.SourceBranchName))) on build variables table are not yet supported in the build pipelines.

Hope this helps.

here's what's working for me:

$(variableName)

for example built-in variable called Build.BuildNumber can be accessed like so:

$(Build.BuildNumber)

full example with format function:

- task: AzurePowerShell@3
  displayName: UpdatePrereq
  inputs:
    azureSubscription: ${{ parameters.azureSubscription }}
    ScriptType: InlineScript
    Inline: |
        ${{ format('. $(Build.Repository.LocalPath)\scripts\_helpers.ps1
        Update-DeploymentPrereq -resourceGroup {1} -location {3}
        Update-Prereq -pathSuffix {0} -pathBase $(Build.Repository.LocalPath) -resourceGroup {1} -buildId $(Build.BuildNumber) -paramFile {2}
        Update-DeploymentConcurrency -resourceGroup {1} -buildId $(Build.BuildNumber)',
            parameters.buildDir, parameters.resourceGroupName, parameters.paramFile, parameters.location ) }}
    azurePowerShellVersion: LatestVersion

If you need to use nested variables you can use something like this:

$name = "CONNECTIONSTRING_$(Agent.MachineName)"
$val = [System.Environment]::GetEnvironmentVariable($name)

And then you get the value of the variable ConnectionString.MACHINENAME
