function Set-WhiskeyVariable { <# .SYNOPSIS Sets a variable for the current build. .DESCRIPTION The `SetVariable` task sets a variable. If the variable doesn't exist, it is added. If it already exists, its value is updated. Variables are referenced in your whiskey.yml file using the syntax `$(VARIABLE NAME)`, where `VARIABLE NAME` is replaced with the name of the variable. Any of Whiskey's pre-defined variables are not allowed to be changed. Attempting to change them will result in a build error. All the task's properties are variable names. Each property's value becomes that variables value. You may reference other variables in a value. They will be replaced with values when they are used, not when they are added by this task. BuildTasks: - SetVariable: ReleaseName: 6.8 BuildMasterPackageName: $(WHISKEY_BUILD_NUMBER)@$(WHISKEY_SCM_BRANCH) Would add a `ReleaseName` variable whose value is `6.8` and a `BuildMasterPackageName` variable whose value is `$(WHISKEY_BUILD_NUMBER)@$(WHISKEY_SCM_BRANCH)`. #> [CmdletBinding()] [Whiskey.Task("SetVariable",SupportsClean=$true,SupportsInitialize=$true)] param( [Parameter(Mandatory=$true)] [object] $TaskContext, [Parameter(Mandatory=$true)] [hashtable] $TaskParameter ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState foreach( $key in $TaskParameter.Keys ) { if( $key -match '^WHISKEY_' ) { Stop-WhiskeyTask -TaskContext $TaskContext -Message ('Variable ''{0}'' is a built-in Whiskey variable and can not be changed.' -f $key) continue } Add-WhiskeyVariable -Context $TaskContext -Name $key -Value $TaskParameter[$key] } } |
