<# .SYNOPSIS This is a Powershell script to bootstrap a Cake build. .DESCRIPTION This Powershell script will download NuGet if missing, restore NuGet tools (including Cake) and execute your Cake build script with the parameters you provide. .PARAMETER Script The build script to execute. .PARAMETER Target The build script target to run. .PARAMETER Configuration The build configuration to use. .PARAMETER Verbosity Specifies the amount of information to be displayed. .PARAMETER Experimental Tells Cake to use the latest Roslyn release. .PARAMETER WhatIf Performs a dry run of the build script. No tasks will be executed. .PARAMETER Mono Tells Cake to use the Mono scripting engine. .LINK http://cakebuild.net #> Param( [string]$Script = "build.cake", [string]$Target = "Default", [string]$Configuration = "Release", [ValidateSet("Quiet", "Minimal", "Normal", "Verbose", "Diagnostic")] [string]$Verbosity = "Verbose", [switch]$Experimental, [Alias("DryRun","Noop")] [switch]$WhatIf, [switch]$Mono, [switch]$SkipToolPackageRestore, [switch]$Verbose ) Write-Host "Preparing to run build script..." # Should we show verbose messages? if($Verbose.IsPresent) { $VerbosePreference = "continue" } $TOOLS_DIR = Join-Path $PSScriptRoot "tools" $NUGET_EXE = Join-Path $TOOLS_DIR "nuget.exe" $CAKE_EXE = Join-Path $TOOLS_DIR "Cake/Cake.exe" $PACKAGES_CONFIG = Join-Path $TOOLS_DIR "packages.config" # Should we use mono? $UseMono = ""; if($Mono.IsPresent) { Write-Verbose -Message "Using the Mono based scripting engine." $UseMono = "-mono" } # Should we use the new Roslyn? $UseExperimental = ""; if($Experimental.IsPresent -and !($Mono.IsPresent)) { Write-Verbose -Message "Using experimental version of Roslyn." $UseExperimental = "-experimental" } # Is this a dry run? $UseDryRun = ""; if($WhatIf.IsPresent) { $UseDryRun = "-dryrun" } # Make sure tools folder exists if ((Test-Path $PSScriptRoot) -and !(Test-Path $TOOLS_DIR)) { New-Item -Path $TOOLS_DIR -Type directory | out-null } # Try download NuGet.exe if not exists if (!(Test-Path $NUGET_EXE)) { Write-Verbose -Message "Downloading NuGet.exe..."
