NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://chocolatey.org/api/v2)

4. Choose your deployment method:


choco upgrade invoke-build -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade invoke-build -y --source="'STEP 3 URL'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

Description

Invoke-Build is a build and test automation tool which invokes tasks defined in PowerShell v2.0+ scripts. It is similar to psake but arguably easier to use and more powerful. It is complete, bug free, well covered by tests.

Features

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

Invoke-Build can invoke the current task from a build script being composed in ISE and VSCode, see Invoke-TaskFromISE.ps1 and Invoke-TaskFromVSCode.ps1.

Invoke-Build can be used as the task runner in VSCode with tasks maintained in a PowerShell build script instead of tasks.json, see New-VSCodeTask.ps1.

Invoke-Build v3.0.1 is cross-platform with PowerShell v6.0.0-alpha.

Notes

  • This package includes Invoke-TaskFromISE, Invoke-TaskFromVSCode, New-VSCodeTask and Invoke-Build.ArgumentCompleters supportive scripts. To setup launch profile in VSCode for build.ps1 files, use the following script path in launch.json:
    json
    "script": "${env:ChocolateyInstall}/lib/invoke-build/tools/Invoke-TaskFromVSCode.ps1"
  • Its recommended to include the following in your PowerShell $PROFILE:
    powershell
    sal ib Invoke-Build
    & $env:ChocolateyInstall\lib\invoke-build\tools\Invoke-Build.ArgumentCompleters.ps1

tools\chocolateyInstall.ps1
$toolsDir = Split-Path $MyInvocation.MyCommand.Definition
$moduleName = 'InvokeBuild'

Write-Host "Installing module $moduleName to $Env:ProgramFiles\WindowsPowerShell\Modules"
$destination = "$Env:ProgramFiles\WindowsPowerShell\Modules\$moduleName\"
if ($PSVersionTable.PSVersion.Major -lt 5)
{
    $source = "$toolsDir\$moduleName\*\*"
} else {
    $source = "$toolsDir\$moduleName\*"
}

# Copy-Item results differ depending on if destination exists or not
if (-not (Test-Path $destination)) {
    mkdir $destination | Out-Null
}
cp $source $destination -Force -Recurse
tools\chocolateyUninstall.ps1
$moduleName = 'InvokeBuild'

    Write-Host "Module not found, it is uninstalled some other way"
    return

	Argument completers for Invoke-Build parameters.

.Description
	The script registers Invoke-Build completers for parameters Task and File.

	Completers can be used with:

	* PowerShell v5 native Register-ArgumentCompleter
	Simply invoke Invoke-Build.ArgumentCompleters.ps1, e.g. in a profile.

	* TabExpansionPlusPlus https://github.com/lzybkr/TabExpansionPlusPlus
	Put Invoke-Build.ArgumentCompleters.ps1 to the TabExpansionPlusPlus module
	directory in order to be loaded automatically. Or invoke it after importing
	the module, e.g. in a profile.

	* TabExpansion2.ps1 https://www.powershellgallery.com/packages/TabExpansion2
	Put Invoke-Build.ArgumentCompleters.ps1 to the path in order to be loaded
	automatically on the first completion. Or invoke after TabExpansion2.ps1,
	e.g. in a profile.

.Synopsis
	Invokes the current task from PowerShell ISE by Invoke-Build.ps1

.Description
	This script invokes the current task from the build script being edited in
	PowerShell ISE. It is invoked either in ISE or in PowerShell console.

	Invoke-Build.ps1 is searched in the directory of Invoke-TaskFromISE.ps1
	and then in the path.

	The current task is the task at the caret line or above. If none is found
	then the default task is invoked. The script is saved if it is modified.

	If the build fails when the task is invoked in ISE and the error location
	is in the same build script then the caret is moved to the error position.

	This script may be called directly from the console pane. But it is easier
	to associate it with key shortcuts. For example, in order to invoke it by
	Ctrl+Shift+T and Ctrl+Shift+B open the ISE profile:

		C:\Users\...\Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1

	and add menu commands and shortcuts:

		# Invoke task in ISE by Invoke-Build.ps1
		$null = $psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add(
		'Invoke Task in ISE', {Invoke-TaskFromISE.ps1}, 'Ctrl+Shift+T')

		# Invoke task in console by Invoke-Build.ps1
		$null = $psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add(
		'Invoke Task in Console', {Invoke-TaskFromISE.ps1 -Console}, 'Ctrl+Shift+B')

	These commands assume that Invoke-TaskFromISE.ps1 is in the path.
	If this is not the case then specify the full script path there.

.Parameter Console
		Tells to invoke the current task in a new PowerShell console.

SHORT DESCRIPTION
    Build and test automation in PowerShell

LONG DESCRIPTION
    The module provides the following commands:

        Invoke-Build
            The alias of Invoke-Build.ps1
            It invokes build scripts, this is the build engine.

        Build-Checkpoint
            The alias of Build-Checkpoint.ps1
            It invokes persistent builds using the engine.

        Build-Parallel
            The alias of Build-Parallel.ps1
            It invokes parallel builds using the engine.

    Import the installed module:

        Import-Module InvokeBuild

    Or import from the specified location:

        Import-Module <path>\InvokeBuild.psd1

    Get help for the engine:

        help <path>\Invoke-Build.ps1 -full

    Get help for build commands:

        . <path>\Invoke-Build.ps1
        help task -full
        help exec -full
        ...

    The package contains the build engine with a few helpers, all you need
    for running build scripts. There are various related tools, see README.

<maml:description>
<maml:para>Invoke-Build - Build Automation in PowerShell</maml:para>
</maml:description>
</command:details>
<maml:description>
<maml:para>The command invokes specified and referenced tasks defined in a PowerShell
script. The process is called build and the script is called build script.

A build script defines parameters, variables, tasks, and blocks. Any code
is invoked with the current location set to $BuildRoot, normally the build
script directory. $ErrorActionPreference is set to &apos;Stop&apos;.

To get help for commands dot-source Invoke-Build:

    PS&gt; . Invoke-Build
    PS&gt; help task -full

USING BUILD SCRIPT PARAMETERS

Build scripts define parameters using param(). They are used in tasks as
$ParameterName for reading and as $script:ParameterName for writing.

The following parameter names are reserved for the engine:
Task, File, Result, Safe, Summary, WhatIf, Log

Script parameters are specified for Invoke-Build as if they are its own.
Known issue #4. Script switches should be specified after Task and File.

RESERVED FUNCTION AND VARIABLE NAMES

Function and variable names starting with &apos;*&apos; are reserved for the engine.
Scripts should not use functions and variables with such names.

EXPOSED FUNCTIONS AND ALIASES

Scripts should use available aliases instead of function names.

    Add-BuildTask (task)
    Assert-Build (assert)
    Assert-BuildEquals (equals)
    Get-BuildError (error)
    Get-BuildProperty (property)
    Get-BuildSynopsis
    Invoke-BuildExec (exec)
    New-BuildJob (job)
    Resolve-MSBuild
    Test-BuildAsset (requires)
    Use-BuildAlias (use)
    Write-Build
    Write-Warning [1]
    Get-BuildFile [2]

[1] Write-Warning is redefined internally in order to count warnings in
tasks, build, and other scripts. But warnings in modules are not counted.

[2] Exists only as a pattern for wrappers.

SPECIAL ALIASES

    Invoke-Build
    Build-Parallel

These aliases are for the scripts Invoke-Build.ps1 and Build-Parallel.ps1.
Use them for calling nested builds, i.e. omit script extensions and paths.
With this rule Invoke-Build tools can be kept together with build scripts.

EXPOSED VARIABLES

Exposed variables designed for build scripts and tasks:

    $WhatIf    - WhatIf mode, Invoke-Build parameter
    $BuildRoot - build script location, by default
    $BuildFile - build script path
    $BuildTask - initial tasks
    $Task      - current task

$BuildRoot may be changed by scripts on loading in order to set a custom
build root directory. Other variables should not be changed.

$Task is available for script blocks defined by task parameters If, Inputs,
Outputs, and Jobs and by blocks Enter|Exit-BuildTask, Enter|Exit-BuildJob,
Set-BuildHeader.

    $Task properties available for reading:

    - Name - [string], task name
    - Jobs - [object[]], task jobs
    - Started - [DateTime], task start time

    In Exit-BuildTask
    - Error - error which stopped the task
    - Elapsed - [TimeSpan], task duration

The variable $_ may be exposed. In special cases it is used as an input.
In other cases build scripts should not assume anything about its value.

BUILD BLOCKS

Scripts may define the following build blocks. They are invoked:

    Enter-Build {} - before all tasks
    Exit-Build {} - after all tasks

    Enter-BuildTask {} - before each task
    Exit-BuildTask {} - after each task

    Enter-BuildJob {} - before each task action
    Exit-BuildJob {} - after each task action

    Set-BuildHeader {param($path)} - custom task header writer

Nested builds do not inherit parent blocks.
If Enter-X is called then Exit-X is called.
Blocks are not called on WhatIf, except Set-BuildHeader.

Enter-Build and Exit-Build are invoked in the script scope. Enter-Build is
a good place for heavy initialization, it does not have to care of WhatIf.
Also, unlike the top level script code, Enter-Build can output text.

Enter-BuildTask, Exit-BuildTask, Enter-BuildJob, and Exit-BuildJob are
invoked in the same scope, the parent of task action blocks.

DOT-SOURCING Invoke-Build

Build-like environment can be imported to normal scripts:

    . Invoke-Build [&lt;root&gt;]

When this command is invoked from a script it

- sets $ErrorActionPreference to Stop
- sets $BuildFile to the invoked script path
- sets $BuildRoot to the script directory or &lt;root&gt;
- sets the current PowerShell location to $BuildRoot
- imports utility commands
    - assert
    - equals
    - exec
    - property
    - requires
    - use
    - Write-Build

Some other build commands are also imported. They are available for getting
help and not designed for use in normal scripts.</maml:para>

<maml:para>One or more tasks to be invoked. If it is not specified, null, empty,
or equal to &apos;.&apos; then the task &apos;.&apos; is invoked if it exists, otherwise
the first added task is invoked.

Names with wildcard characters are reserved for special tasks.

SPECIAL TASKS

? - Tells to list the tasks with brief information without invoking. It
also checks tasks and throws errors on missing or cyclic references.
Task synopsis is defined in preceding comments as # Synopsis: ...

?? - Tells to collect and get all tasks as an ordered dictionary. It
can be used by external tools for analysis, TabExpansion, and etc.

Tasks ? and ?? set $WhatIf to true. Properly designed build scripts
should not perform anything significant if $WhatIf is set to true.

* - Tells to invoke all tasks, for example when tasks are tests.

** - Invokes * for all files *.test.ps1 found recursively in the
current directory or a directory specified by the parameter File.
Other parameters except Result and Safe are ignored.

Tasks ? and ?? can be combined with **
?, ** - To show all test tasks without invoking.
??, ** - To get task dictionaries for all test files.</maml:para>
</maml:description>
</command:parameter>
<command:parameter required="false" position="2" >
<maml:name>File</maml:name>
<maml:description>
<maml:para>A build script which defines tasks by the alias &apos;task&apos; (Add-BuildTask).

If it is not specified then Invoke-Build looks for *.build.ps1 files in
the current location. A single file is used as the script. If there are
more files then .build.ps1 is used if it exists, otherwise build fails.

If the build file is not found then a script defined by the environment
variable InvokeBuildGetFile is called with the path as an argument. For
this location it may return the full path of a special build script.

If the file is still not found then parent directories are searched.

INLINE SCRIPT

`File` is a script block which is normally used in order to assemble a
build on the fly without creating and using an extra build script file.

Script parameters are not supported. Use the parent scope variables
instead, either directly or with the helpers `property` and `requires`.

$BuildRoot is the calling script root (or the current location). If it
is not what the build needs as its root directory, then change this
variable in the beginning of the inline script block.

$BuildFile is the calling script (it may be null, e.g. in jobs).
This variable is rarely used, just keep in mind the difference.

Persistent and parallel builds are not supported.</maml:para>
</maml:description>
</command:parameter>
<command:parameter required="false" position="named" >
<maml:name>Result</maml:name>
<maml:description>
<maml:para>Tells to output build information using a variable. It is either a name
of variable to be created or any object with the property Value to be
assigned (e.g. [ref] or [hashtable]).

Result object properties:

    All - all available tasks
    Error - a terminating build error
    Tasks - invoked tasks including nested
    Errors - error objects including nested
    Warnings - warning objects including nested
    Redefined - list of original redefined tasks

Tasks is a list of objects:

    Name - task name
    Jobs - task jobs
    Error - task error
    Started - start time
    Elapsed - task duration
    InvocationInfo - task location (.ScriptName and .ScriptLineNumber)

Errors is a list of objects:

    Error - original error record
    File - current $BuildFile
    Task - current $Task or null for non-task errors

Warnings is a list of objects:

    Message - warning message
    File - current $BuildFile
    Task - current $Task or null for non-task warnings

These data should be used for reading only.
Other result and task data should not be used.</maml:para>
</maml:description>
</command:parameter>
<command:parameter required="false" position="named" >
<maml:name>Safe</maml:name>
<maml:description>
<maml:para>Tells to catch a build failure, store an error as the property Error of
Result and return quietly. A caller should use Result and check Error.

Some exceptions are possible even in the safe mode. They show serious
errors, not build failures. For example, a build script is missing.

When Safe is used together with the special task ** (invoke *.test.ps1)
then task failures stop current test scripts, not the whole testing.</maml:para>

<maml:name>WhatIf</maml:name>
<maml:description>
<maml:para>Tells to show preprocessed tasks and their scripts instead of invoking
them. If a script does anything but adding and configuring tasks then
it should check for $WhatIf and skip some significant actions.</maml:para>

<maml:para>Scripts use its alias &apos;task&apos;. This is the main feature of build scripts. At
least one task must be added. Normally it is used in the build script scope
but it can be called anywhere, e.g. imported, created dynamically, and etc.

In fact, this function is literally all that build scripts really need.
Other build functions are just helpers, scripts do not have to use them.

Task help-comments are special comments preceding task definitions

<maml:name>If</maml:name>
<maml:description>
<maml:para>Specifies the optional condition to be evaluated. If the condition
evaluates to false then the task is not invoked. The condition is
defined in one of two ways depending on the requirements.

Using standard Boolean notation (parenthesis) the condition will only
be evaluated when the task is loaded into the build engine. A use case
for this notation might be evaluating parameters that are passed into
the build.

    Example:
        task SomeTask -If ($SomeCondition) {...}

Using script block notation (curly braces) the condition will be
evaluated dynamically on task invocation. If a task is referenced by
several tasks then the condition is evaluated each time until it gets
true and the task is invoked. The script block notation is normally
used for a condition that may be defined or changed during the build.

    Example:
        task SomeTask -If {$SomeCondition} {...}

On WhatIf:
- Boolean conditions are evaluated and treated accordingly.
- Script block conditions are treated as true without invocation.</maml:para>

<maml:name>Inputs</maml:name>
<maml:description>
<maml:para>Specifies the input items, tells to process the task as incremental,
and requires the parameter Outputs with the optional switch Partial.

Inputs are file items or paths or a script block which gets them.

Outputs are file paths or a script block which gets them.
A script block is invoked with input paths piped to it.

Automatic variables for incremental task actions:

    $Inputs - full input paths, array of strings
    $Outputs - result of the evaluated Outputs

With the switch Partial the task is processed as partial incremental.
There must be one-to-one correspondence between Inputs and Outputs.

Partial task actions often contain &quot;process {}&quot; blocks.
Two more automatic variables are available for them:

    $_ - full path of an input item
    $2 - corresponding output path

<maml:para>Tasks with complex parameters are often difficult to compose in a readable
way. Use PowerShell splatting or add the above helper `taskx` to a script
in order to compose parameters as hashtables.</maml:para>

in order to make framework tools available by names. This is not suitable
for using mixed framework tools (in different tasks, scripts, parallel
builds). Instead, this function is used for setting tool aliases in the
scope where it is called from.

This function is often called from a build script and all tasks use script
scope aliases. But it can be called from tasks in order to use more tools
including other framework or tool directories.</maml:para>

If it is like Framework* then it is assumed to be a path relative to
Microsoft.NET in the Windows directory.

<command:name>Build-Checkpoint.ps1</command:name>
<maml:description>
<maml:para>Invokes persistent builds with checkpoints.</maml:para>
</maml:description>
</command:details>
<maml:description>
<maml:para>This command invokes the build specified by the hashtable Build so that it
writes checkpoints to the file specified by Checkpoint. If the build fails
then it may be resumed later, use the switch Resume in addition to the
original Checkpoint parameter. The build is resumed at the failed task.

Not every build may be persistent, right away or at all:

    - Think carefully of what the persistent build state is.
    - Some data are not suitable for persistence in clixml files.
    - Changes in stopped build scripts may cause incorrect resuming.
    - Checkpoint files must not be used with different engine versions.

CUSTOM EXPORT AND IMPORT

By default, the command saves and restores build tasks, script path, and
all parameters declared by the build script, not just specified by Build.
Tip: consider to declare some script variables as artificial parameters
in order to make them persistent.

If this is not enough for saving and restoring the build state then use
custom export and import blocks. The export block is called on writing
checkpoints, i.e. on each task. The import block is called on resuming
once, before the task to be resumed.

The export block is defined as

    Set-BuildData Checkpoint.Export {
        $script:var1
        $script:var2
    }

The import block is defined as

    Set-BuildData Checkpoint.Import {
        param($data)
        $var1, $var2 = $data
    }

Note that the import block is called in the script scope. In the example,
variables $var1, $var2 are the script variables, you may but do not have
to use the prefix `$script:`. The parameter $data is the data written by
Checkpoint.Export, exported to clixml and then imported from clixml.</maml:para>

	It is designed to work for MSBuild 2.0-15.0 and support future versions.

	For MSBuild 15.0+ the command uses VSSetup module from PSGallery.
	If it is not installed then some default locations are checked.
	Thus, VSSetup module is required for not default installations.

	MSBuild 15.0+ resolution precedence: Enterprise, Professional, Community,
	another product. If this is not suitable then use VSSetup module directly.

	For MSBuild 2.0-14.0 the information is taken from the registry.

.Parameter Version
		Specifies the required MSBuild version. If it is omitted, empty, or *
		then the command finds and returns the latest installed version path.
		The optional suffix x86 tells to use 32-bit MSBuild.

.Outputs
	The full path to MSBuild.exe

.Example
	Resolve-MSBuild 15.0
	Gets location of MSBuild installed with Visual Studio 2017.

.Synopsis
	Makes VSCode tasks from Invoke-Build tasks

.Description
	The script creates "./.vscode/tasks.json". The existing file is replaced.
	Change to the VSCode workspace directory before invoking the script.
	Generated VSCode tasks call Invoke-Build tasks.

	Do not edit "tasks.json" directly. Edit the build script instead. When you
	add, remove, rename tasks, or change script locations then regenerate.

	The default task becomes the so called VSCode build task (Ctrl+Shift+B).
	The default task is "." if it exists, otherwise it is the first task.

	To invoke another task from VSCode, hit F1 or Ctrl+Shift+P, type "Run
	Task", type a task name or select it from the task list. Even better,
	set your keyboard shortcut for "workbench.action.tasks.runTask".

	Only tasks with certain names are included. They contain alphanumeric
	characters, "_", ".", and "-", with the first character other than "-".

.Parameter BuildFile
		Specifies the build script path, absolute or relative. By default it is
		the default script in the current location, i.e. in the workspace root.
.Parameter InvokeBuild
		Specifies the Invoke-Build.ps1 path, absolute or relative. If it is not
		specified then any found in the workspace is used. If there is none
		then the command Invoke-Build is used.

.Example
	> New-VSCodeTask
	This command binds to the default build script in the workspace root and
	Invoke-Build.ps1 either in the workspace root or subdirectory or in the
	path or the module command.

.Example
	> New-VSCodeTask ./Scripts/Build.ps1 ./packages/InvokeBuild/Invoke-Build.ps1
	This command uses relative build and engine script paths. The second may be
	omitted, Invoke-Build.ps1 will be discovered. But it is needed if there may
	be several Invoke-Build.ps1 in the workspace.
