Inject command line arguments into psake

The latest release of psake now supports passing parameters to Invoke-psake, e.g.

Invoke-psake .\parameters.ps1 -parameters @{"p1"="v1";"p2"="v2"} 

This feature has just been added. :)

A global variable will solve my problem for now and with only one reference to $global:arg_environent it will be easy to change if i find a better way to inject the properties.

build.ps1

param(    [Parameter(Position=0,Mandatory=0)]    [string]$task,    [Parameter(Position=1,Mandatory=0)]    [string]$environment = 'dev')clear$global:arg_environent = $environmentImport-Module .\psake.psm1 Invoke-psake tasks.ps1 $taskRemove-Module psake

tasks.ps1

properties {    $environment = $global:arg_environent}task default -depends Deploytask Deploy {     echo "Copy stuff to $environment"}

I'm no expert, but I don't think it is possible to pass arguments to Invoke-Psake. Looking on the latest source for Psake the params for the Invoke-Psake function are:

param(    [Parameter(Position=0,Mandatory=0)]    [string]$buildFile = 'default.ps1',    [Parameter(Position=1,Mandatory=0)]    [string[]]$taskList = @(),    [Parameter(Position=2,Mandatory=0)]    [string]$framework = '3.5',       [Parameter(Position=3,Mandatory=0)]    [switch]$docs = $false        )

There are 4 parameters, your build file, a list of tasks, the .NET framework version, whether to output docs of your tasks. I'm new to powershell and psake and I'm trying to do the same thing, I am experimenting with doing something like this in my script to achieve the same thing:

properties {    $environment = "default"}task PublishForLive -precondition { $environment = "Live"; return $true; } -depends Publish {}task PublishForStaging -precondition { $environment = "Staging"; return $true; } -depends Publish {}task Publish {    Write-Host "Building and publishing for $environment environment"    #Publish the project...}

Then calling psake with PublishForLive or PublishForStaging, whichever I need:

powershell -NoExit -ExecutionPolicy Unrestricted -Command "& {Import-Module .\tools\psake\psake.psm1; Invoke-psake .\psake-common.ps1 PublishForLive }"

But it doesn't seem to work for me! Setting the $environment variable in the task precondition seems to have no effect. Still trying to make this work...
