Why are my PowerShell exit codes always “0”?

Question

I\'ve got a PowerShell script as follows

##teamcity[progressMessage \'Beginning build\']
# If the build computer is not running the appropriate version of .N         


        

Answer 1

I was having this exact issue while running with the -file, but for some reason the trap syntax or the 'exit' syntax provided by Kevin wasn't working in my scenario.

I am not sure why, but just in case somebody else hits the same problem, I used the below syntax and it worked for me:

try{
    #DO SOMETHING HERE
}
catch
{
    Write-Error $_
    ##teamcity[buildStatus status='FAILURE']
    [System.Environment]::Exit(1)
}
