我正在编写一些发布自动化脚本,这些脚本使用 Powershell 来更新执行各种应用程序的现有计划任务。在我的脚本中,我可以设置应用程序的路径和工作目录,但它似乎不会将更改保存回任务。
function CreateOrUpdateTaskRunner {
param (
[Parameter(Mandatory = $TRUE, Position = 1)][string]$PackageName,
[Parameter(Mandatory = $TRUE, Position = 2)][Version]$Version,
[Parameter(Mandatory = $TRUE, Position = 3)][string]$ReleaseDirectory
)
$taskScheduler = New-Object -ComObject Schedule.Service
$taskScheduler.Connect("localhost")
$taskFolder = $taskScheduler.GetFolder('\')
foreach ($task in $taskFolder.GetTasks(0)) {
# Check each action to see if it references the current package
foreach ($action in $task.Definition.Actions) {
# Ignore actions that do not execute code (e.g. send email, show message)
if ($action.Type -ne 0) {
continue
}
# Ignore actions that do not execute the specified task runner
if ($action.WorkingDirectory -NotMatch $application) {
continue
}
# Find the executable
$path = Join-Path $ReleaseDirectory -ChildPath $application | Join-Path -ChildPath $Version
$exe = Get-ChildItem $path -Filter "*.exe" | Select -First 1
# Update the action with the new working directory and executable
$action.WorkingDirectory = $exe.DirectoryName
$action.Path = $exe.FullName
}
}
}
到目前为止,我无法在文档中找到明显的保存功能(https://msdn.microsoft.com/en-us/library/windows/desktop/aa383607(v=vs.85).aspx)。我在这里采取的方法是否错误,需要弄乱任务 XML?
答案1
这注册任务方法有一个你可以使用的更新标志。如下所示:
# Update the action with the new working directory and executable
$action.WorkingDirectory = $exe.DirectoryName
$action.Path = $exe.FullName
#Update Task
$taskFolder.RegisterTask($task.Name, $task.Definition, 4, "<username>", "<password>", 1, $null)
有关每个参数的详细信息,请参阅 msdn 文章。
