This is an entry point for the project-specific build script. .DESCRIPTION It does the following steps: 1. Loads build files (Powershell functions) available at $ScriptsDirectory. 2. If $BuildParams.Tasks are specified, runs the tasks (Powershel functions) in the specified order. 3. If $BuildParams.Tasks is not specified, runs task named $DefaultTask. When task is run, parameters are automatically passed from build.ps1 to the task. .PARAMETER BuildParams Parameters specified in build.ps1 script. .PARAMETER ScriptsDirectory Directory containing custom build script files. .PARAMETER DefaultTask Default task to run if $BuildParams.Tasks is not specified. .EXAMPLE $buildParams = (Get-Command -Name $PSCmdlet.MyInvocation.InvocationName).Parameters Start-Build -BuildParams $buildParams -ScriptsDirectory 'build' -DefaultTask 'Build-All' #> [CmdletBinding()] [OutputType([void])] param( [Parameter(Mandatory=$true)] [object[]] $BuildParams, [Parameter(Mandatory=$true)] [string] $ScriptsDirectory, [Parameter(Mandatory=$true)] [string] $DefaultTask ) $buildParamsHash = @{} foreach ($param in $BuildParams) { $buildParamsHash[$param.Name] = $param.Value } if (!(Test-Path -LiteralPath $ScriptsDirectory -PathType Container)) { throw "Directory '$ScriptsDirectory' does not exist.
