使用 -File 参数调用时，如何让 powershell 返回正确的退出代码? [英] How can I get powershell to return the correct exit code when called with the -File argument?

问题描述

如果使用 -File 参数调用，则发生错误时，Powershell 将返回 0 退出代码.这意味着我的构建在不应该是绿色的时候是绿色的:(

Powershell is returning a 0 exit code, when an error has occurred, if called with the -File argument. Which means my build is green when it shouldn't be :(

例如:

(在 wtf.ps1 中)

(in wtf.ps1)

$ErrorActionPreference = "Stop";   
$null.split()

(命令)

powershell -file c:\wtf.ps1  
You cannot call a method on a null-valued expression.
At C:\wtf.ps1:3 char:12
+ $null.split <<<< ()
    + CategoryInfo          : InvalidOperation: (split:String) [], ParentConta
   insErrorRecordException
    + FullyQualifiedErrorId : InvokeMethodOnNull


echo %errorlevel%  
0

powershell c:\wtf.ps1  
You cannot call a method on a null-valued expression.
At C:\wtf.ps1:3 char:12
+ $null.split <<<< ()
    + CategoryInfo          : InvalidOperation: (split:String) [], ParentConta
   insErrorRecordException
    + FullyQualifiedErrorId : InvokeMethodOnNull


echo %errorlevel%  
1

有什么想法吗?

(我已经尝试了前两页中的几乎所有想法:https://www.google.co.uk/search?q=powershell+file+argument+exit+code 已经)

推荐答案

在脚本中，使用带有您选择的数字的 exit 关键字:

In the script, use the exit keyword with a number of your choice:

exit 34

这是我用来测试这个的脚本:

Here's the script I used to test this:

## D:\Scripts\Temp\exit.ps1 ##
try{
    $null.split()
}
catch
{
    exit 34
}

exit 2

# launch powershell from cmd 
C:\> powershell -noprofile -file D:\Scripts\Temp\exit.ps1
C:\>echo %errorlevel%
34
