function Invoke-WhiskeyPipeline { <# .SYNOPSIS Invokes Whiskey pipelines. .DESCRIPTION The `Invoke-WhiskeyPipeline` function runs the tasks in a pipeline. Pipelines are properties in a `whiskey.yml` under which one or more tasks are defined. For example, this `whiskey.yml` file: Build: - TaskOne - TaskTwo Publish: - TaskOne - Task Defines two pipelines: `Build` and `Publish`. .EXAMPLE Invoke-WhiskeyPipeline -Context $context -Name 'Build' Demonstrates how to run the tasks in a `Build` pipeline. The `$context` object is created by calling `New-WhiskeyContext`. #> [CmdletBinding()] param( [Parameter(Mandatory=$true)] [object] # The current build context. Use the `New-WhiskeyContext` function to create a context object. $Context, [Parameter(Mandatory=$true)] [string] # The name of pipeline to run, e.g. `Build` would run all the tasks under a property named `Build`. Pipelines are properties in your `whiskey.yml` file that are lists of Whiskey tasks to run. $Name ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState $config = $Context.Configuration $Context.PipelineName = $Name if( -not $config.ContainsKey($Name) ) { Stop-Whiskey -Context $Context -Message ('Pipeline ''{0}'' does not exist.
