![Windows 任务计划程序不显示执行错误](https://linux22.com/image/678831/Windows%20%E4%BB%BB%E5%8A%A1%E8%AE%A1%E5%88%92%E7%A8%8B%E5%BA%8F%E4%B8%8D%E6%98%BE%E7%A4%BA%E6%89%A7%E8%A1%8C%E9%94%99%E8%AF%AF.png)
我正在尝试制作一个可以通过 Windows 任务计划程序不时运行的 powerscript。
我的问题是,即使我的脚本确实失败了,任务调度程序也不会显示任务失败。
这是我得到的事件:

我已经通过调用脚本中的以下内容创建了任务本身:
function Create-Task
{
Param($name, $description)
$trigger = New-JobTrigger -Daily -At 1am
$options = New-ScheduledJobOption -WakeToRun -RequireNetwork
Register-ScheduledJob -Name $name -FilePath $MyInvocation.PSCommandPath -ArgumentList "Run", $MyInvocation.PSScriptRoot -Trigger $trigger -ScheduledJobOption $options
}
知道为什么我没有收到漂亮的红色错误吗?
答案1
即使 PowerShell 脚本失败,PowerShell.exe 通常也不会返回错误代码。只有无法加载 PowerShell 脚本时,它才会返回非零错误代码。
我通常使用以下命令行来让我的进程在脚本失败时返回非零错误代码:
PowerShell.exe -Command "& {& 'C:\MyPowerShellScript.ps1' ; EXIT $LASTEXITCODE }"
如果脚本中的某些内容失败,整个过程将返回非零错误级别,然后任务计划程序就可以检测到。
