Build Automation in PowerShell

Invoke-Build is a build and test automation tool which invokes tasks defined in PowerShell scripts. It is similar to psake but arguably easier to use and more powerful.

In addition to basic task processing the engine supports

  • Incremental tasks with effectively processed inputs and outputs.
  • Persistent builds which can be resumed after interruptions.
  • Parallel builds as a part of another with common stats.
  • Batch invocation of tests composed as tasks.
  • Ability to define new classes of tasks.

The package

The standalone script Invoke-Build.ps1 is enough for invoking build scripts. It can be downloaded directly from the repository and used right away. The package also includes helper scripts and the help file:

  • Invoke-Build.ps1 - invokes build scripts, this is the build engine
  • Invoke-Builds.ps1 - invokes parallel builds using the engine
  • Invoke-Build-Help.xml - external content for Get-Help
  • ib.cmd - Invoke-Build helper for cmd.exe

Extra tools are available at the project repository:

  • Convert-psake.ps1 - converts psake build scripts
  • Invoke-TaskFromISE.ps1 - invokes a task from ISE
  • Show-BuildTree.ps1 - shows task trees as text
  • Show-BuildGraph.ps1 - shows task trees by Graphviz
  • TabExpansionProfile.Invoke-Build.ps1 - code completers

Installation

Invoke-Build is distributed as the NuGet package Invoke-Build. Download it to the current location as the directory "Invoke-Build" by this PowerShell command:

iex (New-Object Net.WebClient).DownloadString('https://github.com/nightroman/Invoke-Build/raw/master/Download.ps1')

Alternatively, get it by NuGet tools or download. In the latter case rename the package to ".zip" and unzip. Use the package subdirectory "tools".

This is it, scripts are ready to use. Consider to include the directory with scripts to the system path so that script paths may be omitted in commands.

With cmd.exe use the helper ib.cmd. For similar experience in interactive PowerShell use an alias ib defined in a PowerShell profile

Set-Alias ib <path>\Invoke-Build.ps1

<path>\ may be omitted if the script is in the path.

Getting help

Make sure Invoke-Build-Help.xml from the package is in the same directory as Invoke-Build.ps1 and invoke

help Invoke-Build -full

In order to get help for commands, at first dot-source Invoke-Build:

. Invoke-Build

This imports commands and makes their help available:

help task -full

The project was inspired by psake. Some concepts come from MSBuild.
