.DESCRIPTION Bootstrap and build script for PowerShell module CI/CD pipeline .PARAMETER Tasks The task or tasks to run. The default value is '.' (runs the default task). .PARAMETER CodeCoverageThreshold The code coverage target threshold to uphold. Set to 0 to disable. The default value is '' (empty string). .PARAMETER BuildConfig Not yet written. .PARAMETER OutputDirectory Specifies the folder to build the artefact into. The default value is 'output'. .PARAMETER BuiltModuleSubdirectory Subdirectory name to build the module (under $OutputDirectory). The default value is '' (empty string). .PARAMETER RequiredModulesDirectory Can be a path (relative to $PSScriptRoot or absolute) to tell Resolve-Dependency and PSDepend where to save the required modules. It is also possible to use 'CurrentUser' och 'AllUsers' to install missing dependencies. You can override the value for PSDepend in the Build.psd1 build manifest. The default value is 'output/RequiredModules'. .PARAMETER PesterScript Not yet written. .PARAMETER PesterTag Filter which tags to run when invoking Pester tests. This is used in the Invoke-Pester.pester.build.ps1 tasks. .PARAMETER PesterExcludeTag Filter which tags to exclude when invoking Pester tests. This is used in the Invoke-Pester.pester.build.ps1 tasks. .PARAMETER DscTestTag Filter which tags to run when invoking DSC Resource tests. This is used in the DscResource.Test.build.ps1 tasks. .PARAMETER DscTestExcludeTag Filter which tags to exclude when invoking DSC Resource tests. This is used in the DscResource.Test.build.ps1 tasks. .PARAMETER ResolveDependency Not yet written. .PARAMETER BuildInfo The build info object from ModuleBuilder. Defaults to an empty hashtable. .PARAMETER AutoRestore Not yet written. #> [CmdletBinding()] param ( [Parameter(Position = 0)] [System.String[]] $Tasks = '.', [Parameter()] [System.String] $CodeCoverageThreshold = '', [Parameter()] [System.String] [ValidateScript( { Test-Path -Path $_ } )] $BuildConfig, [Parameter()] [System.String] $OutputDirectory = 'output', [Parameter()] [System.String] $BuiltModuleSubdirectory = '', [Parameter()] [System.String] $RequiredModulesDirectory = $(Join-Path 'output' 'RequiredModules'), [Parameter()] [System.Object[]] $PesterScript, [Parameter()] [System.String[]] $PesterTag, [Parameter()] [System.String[]] $PesterExcludeTag, [Parameter()] [System.String[]] $DscTestTag, [Parameter()] [System.String[]] $DscTestExcludeTag, [Parameter()] [Alias('bootstrap')] [System.Management.Automation.SwitchParameter] $ResolveDependency, [Parameter(DontShow)] [AllowNull()] [System.Collections.Hashtable] $BuildInfo, [Parameter()] [System.Management.Automation.SwitchParameter] $AutoRestore ) <# The BEGIN block (at the end of this file) handles the Bootstrap of the Environment before Invoke-Build can run the tasks if the parameter ResolveDependency (or parameter alias Bootstrap) is specified. #> process { if ($MyInvocation.ScriptName -notLike '*Invoke-Build.ps1') { # Only run the process block through InvokeBuild (look at the Begin block at the bottom of this script). return } # Execute the Build process from the .build.ps1 path.
