我想在PowerShell中编写类似CSharp watch任务的东西。所以，我想要发生的是当CSharp文件在某个目录中发生更改时，它会尝试查找csproj文件并启动构建。我如何在PowerShell中运行PowerShell中的MSBuild任务
这是我目前有
function Watch-CSharp-Files() {
set-location "D:\path\to\csharp\files\"
$originalPath = Get-Location
Write-host "Welcome to The Watcher. It keeps track of changing files in this solution directory (including subdirectories) and triggers a build when something changes..."
$existingEvents = get-eventsubscriber
foreach ($item in $existingEvents) {
Unregister-event -SubscriptionId $item.SubscriptionId
write-host "Unsubscribed existing event:" $item.Action.Name
}
$folder = get-location
$filter = '*.*'
$watcher = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $true;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}
Register-ObjectEvent $watcher Changed -SourceIdentifier FileChanged -Action {
$path = $Event.SourceEventArgs.FullPath
if ($path -match "(\.cs~|.cs$)") {
write-host "file changed: $path"
Invoke-Expression -Command "Find-And-Build-Project '$path'"
}
}
}
function Find-And-Build-Project([string]$path) {
write-host "BUILD PROJECT REPORTING FOR DUTY"
$pathParts = "$path".Split("\\")
$end = $pathParts.Count - 2 # skip the file name to the parent directory
$testPath = $pathParts[0..$end] -join "\"
write-host "testing path $testPath"
$csproj = Get-ChildItem -path $testPath *.csproj
For ($i = 0; $i -le 10; $i++) {
$newEnd = $end - $i
$newPath = $pathParts[0..$newEnd] -join "\"
$csproj = Get-ChildItem -path $newPath *.csproj
write-host "$i. trying: $newPath, csproj: $csproj"
if ($csproj) {
write-host "found on $i, at $newPath, $csproj"
break
}
}
write-host "Ready: $newPath\$csproj"
$msbuild = "C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe"
write-host "trying to MSBUILD"
& $msbuild ("$newPath\$csproj", "/target:Build", "/p:configuration=debug", "/verbosity:n")
}
Watch-CSharp-Files
我发现是函数Find-And-Build-Project，内& $msbuild不会被调用。但是，我不明白为什么。
任何想法？
