How to set an environment variable with PowerShell in Azure Devops release pipeline?

Question

I have a function which will return a result. I am setting that result as an environment value in a pipeline. When I am invoking environment variable it's not printing the next two lines.

Write-Host "Before env : $result"
write-host "##vso[task.setvariable variable=message]$result"
[![enter code here][1]][1]

In other stage I invoked message other variable but it's not printing the next two lines.

write-host "After env :  $(message)"
[![enter code here][2]][2]

My only challenge was not getting the last two lines which is ASDB_REPORT / ASDB_REPORT_TEST

Hi Bala, Does my answer work? Please check it and kindly let me know the result. — Edward Han-MSFT

If you set an environment variable with PowerShell in release pipeline, please refer to this doc: Set variables in scripts.

$result = 'crushed tomatoes'

Write-Host "##vso[task.setvariable variable=sauce]$result"

# Write-Host "sauce: $(sauce)"

Please note that "Subsequent steps will also have the pipeline variable added to their environment. You cannot use the variable in the step that it is defined." Thus you could access to the new variable with macro syntax and in tasks as environment variables.

Write-Host "sauce: $(sauce)"

Write-Host "my environment variable is $env:SAUCE"

However, you can't pass a variable from one job to another job or from one stage to another stage of release pipeline, unless you use multi-stages YAML. Please refer to Set a multi-job output variable for details.
