PowerShell FileSystemWatcher不支持'；t在执行计划任务时运行

我有一个PowerShell脚本StartWatching.ps1，它使用FileSystemWatcher监视文件夹：

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
    $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "C:\ScheduledTasks\PlanUpdates"
    $watcher.Filter = "*.sql"
    $watcher.IncludeSubdirectories = $false
    $watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER A EVENT IS DETECTED
    $action = { 
            $path = $Event.SourceEventArgs.FullPath
            $changeType = $Event.SourceEventArgs.ChangeType
            $logline = "$(Get-Date), Processed, $path"
            Add-content "C:\ScheduledTasks\PlanUpdates\log.txt" -value $logline
            cmd.exe /c 'C:\ScheduledTasks\PlanUpdates\planUpdate.bat'
              }    
### DECIDE WHICH EVENTS SHOULD BE WATCHED + SET CHECK FREQUENCY  
    $created = Register-ObjectEvent $watcher "Created" -Action $action
    while ($true) {sleep 1}

每当在文件夹中创建.sql文件时，脚本就会启动.bat文件planUpdate.bat。.bat文件在特定sql server上执行.sql文件的内容（数据库在.sql文件中声明），然后将该文件移动到子文件夹“Old”：

它会打开一个命令窗口，就像脚本正在运行一样，但FileSystemWatcher不会注册任何事件

我希望你能帮忙，因为我一整天都在努力解决这个问题

以下是任务xml：

我遇到了同样的问题

我不知道为什么会这样，但试着改变一下

powershell -noexit -file C:\ScheduledTasks\PlanUpdates\StartWatching.ps1

您需要给出任务定义。导出它并在此处提供XML或提供等效的

schtasks.exe

命令。我添加了任务XML。@KHH您好您找到过解决方案吗？
