为什么我的 PowerShell 退出代码总是“0"? [英] Why are my PowerShell exit codes always "0"?
问题描述
我有一个 PowerShell 脚本如下
I've got a PowerShell script as follows
##teamcity[progressMessage 'Beginning build']
# If the build computer is not running the appropriate version of .NET, then the build will not run. Throw an error immediately.
if( (ls "$env:windir\Microsoft.NET\Framework\v4.0*") -eq $null ) {
throw "This project requires .NET 4.0 to compile. Unfortunately .NET 4.0 doesn't appear to be installed on this machine."
##teamcity[buildStatus status='FAILURE' ]
}
##teamcity[progressMessage 'Setting up variables']
# Set up variables for the build script
$invocation = (Get-Variable MyInvocation).Value
$directorypath = Split-Path $invocation.MyCommand.Path
$v4_net_version = (ls "$env:windir\Microsoft.NET\Framework\v4.0*").Name
$nl = [Environment]::NewLine
Copy-Item -LiteralPath "$directorypath\packages\NUnit.2.6.2\lib\nunit.framework.dll" "$directorypath\Pandell.Tests\bin\debug" -Force
##teamcity[progressMessage 'Using msbuild.exe to build the project']
# Build the project using msbuild.exe.
# Note we've already determined that .NET is already installed on this computer.
cmd /c C:\Windows\Microsoft.NET\Framework\$v4_net_version\msbuild.exe "$directorypath\Pandell.sln" /p:Configuration=Release
cmd /c C:\Windows\Microsoft.NET\Framework\$v4_net_version\msbuild.exe "$directorypath\Pandell.sln" /p:Configuration=Debug
# Break if the build throws an error.
if(! $?) {
throw "Fatal error, project build failed"
##teamcity[buildStatus status='FAILURE' ]
}
##teamcity[progressMessage 'Build Passed']
# Good, the build passed
Write-Host "$nl project build passed." -ForegroundColor Green
##teamcity[progressMessage 'running tests']
# Run the tests.
cmd /c $directorypath\build_tools\nunit\nunit-console.exe $directorypath\Pandell.Tests\bin\debug\Pandell.Tests.dll
# Break if the tests throw an error.
if(! $?) {
throw "Test run failed."
##teamcity[buildStatus status='FAILURE' ]
}
##teamcity[progressMessage 'Tests passed']
据我所知,未捕获的 Throw
将导致退出代码 1
,但不幸的是 TeamCity 另有说法.
From what I'm lead to believe, an uncaught Throw
will result in an exit code of 1
, but unfortunately TeamCity is saying otherwise.
[19:32:20]Test run failed.
[19:32:20]At C:\BuildAgent\work\e903de7564e599c8\build.ps1:44 char:2
[19:32:20]+ throw "Test run failed."
[19:32:20]+ ~~~~~~~~~~~~~~~~~~~~~~~~
[19:32:20] + CategoryInfo : OperationStopped: (Test run failed.:String) [],
[19:32:20] RuntimeException
[19:32:20] + FullyQualifiedErrorId : Test run failed.
[19:32:20]
[19:32:20]Process exited with code 0
[19:32:20]Publishing internal artifacts
[19:32:20][Publishing internal artifacts] Sending build.finish.properties.gz file
[19:32:20]Build finished
需要注意的是,我的 Execution Mode
设置为 Execute .ps1 script with "-File" argument
.
It might also be important to note that my Execution Mode
is set to Execute .ps1 script with "-File" argument
.
我尝试将其更改为 Put script into PowerShell stdin with "-Command -" arguments
,但是即使通过了测试,它也失败了,退出代码为 1
.我确信将它作为 -File
运行将是正确的方式.
I tried changing it to Put script into PowerShell stdin with "-Command -" arguments
, but then it failed with an exit code of 1
even with passing tests. I'm sure that running it as -File
is going to be the right way.
如果我打开位于 C:\BuildAgent\work\e903de7564e599c8\build.ps1
的脚本并在 CMD 中手动运行它,它会做同样的事情......即失败的测试失败,并且 %errorlevel%
仍然是 0
.
If I open up the script located at C:\BuildAgent\work\e903de7564e599c8\build.ps1
and run it manually in CMD, it does the same thing... I.e., the failing tests fail, and the %errorlevel%
is still 0
.
然而,如果我在 PowerShell 中运行它并调用 $LASTEXITCODE
,它每次都会返回正确的代码.
Yet, if I run it in PowerShell and call $LASTEXITCODE
, it returns the right code every time.
推荐答案
这是 PowerShell 的一个已知问题.使用 -file
执行脚本会在不应该返回 0 的退出代码.
This is a known issue with PowerShell. Executing a script with -file
returns an exit code of 0 when it shouldn't.

由于使用 -command
对您不起作用,您可以尝试在脚本顶部添加陷阱:
Since using -command
wasn't working for you, you could try adding a trap at the top of the script:
trap
{
write-output $_
##teamcity[buildStatus status='FAILURE' ]
exit 1
}
当抛出异常时,上面应该会产生一个正确的退出代码.
The above should result in a proper exit code when an exception is thrown.
