.SYNOPSIS Invokes a NuGet command .DESCRIPTION The Invoke-ISNuGetCommand cmdlet is a wrapper around NuGet.exe. Running the cmdlet will allow you to run various forms of NuGet commands. The output from the cmdlet will be the exact same as a running a regular instance of NuGet.exe with the same parameters. If an argument does not require a parameter, pass $null as the parameter. .EXAMPLE $NuGetArguments = @{ "SomePackageName" = $null '-NonInteractive' = $null -OutputDirectory' = C:\Temp\ } Invoke-ISNuGetCommand -Action "install" -Arguments $NugetCommand .INPUTS String, Hashtable .OUTPUTS String #> function Invoke-ISNuGetCommand { [CmdletBinding()] param ( [Parameter(Mandatory)] [ValidateNotNullOrEmpty()] [ValidateSet('list', 'install', 'setApiKey', 'sources', 'config', 'locals', 'update')] [string]$Action, [Parameter(Mandatory)] [ValidateNotNullOrEmpty()] [hashtable]$Arguments ) try { $argArr = @() $argArr += $Arguments.GetEnumerator() | Sort-Object Value | ForEach-Object { if (-not $_.Value) { '"{0}"' -f $_.Key } else { '-{0} "{1}"' -f $_.Key, $_.Value } } $argString = $argArr -join ' ' $stdOutTempFile = [System.IO.Path]::GetTempFileName() $stdErrTempFile = [System.IO.Path]::GetTempFileName() $startProcessParams = @{ FilePath = $NUGET_EXE ArgumentList = "$Action $argString" RedirectStandardError = $stdErrTempFile RedirectStandardOutput = $stdOutTempFile Wait = $true PassThru = $true NoNewWindow = $true } Write-Verbose -Message ("Running command: {0} {1}" -f $startProcessParams.FilePath, $startProcessParams.ArgumentList) $cmd = Start-Process @startProcessParams $cmdOutput = Get-Content -Path $stdOutTempFile -Raw $cmdError = Get-Content -Path $stdErrTempFile -Raw if ($cmd.ExitCode -ne 0) { throw $cmdError } else { $cmdOutput } } catch { $PSCmdlet.ThrowTerminatingError($_) } finally { Remove-Item -Path $stdOutTempFile, $stdErrTempFile -Force } } |
