Scope of functions defined in modules when used in psake tasks

I created a script module test-module.psm1:

function Invoke-Test {    Import-Module ".\somefunctions.psm1"    Import-Module ".\morefunctions.psm1"    Set-Something #This is a function defined in morefunctions.psm1}

and a couple of dummy modules, somefunctions.psm1:

function Get-Something {    'Get-Something'}

and morefunctions.psm1:

function Set-Something {    Get-Something    'Set-Something'}

If I call

Import-Module .\test-module.psm1Invoke-Test

then I get the error "Get-Something : The term 'Get-Something' is notrecognized as the name of a cmdlet, function, script file, or operableprogram.". So it looks like a generic PowerShell issue dealing with scriptmodules. I tried PowerShell v2.0, v3.0, and v4.0.

Perhaps this cannot be resolved in psake without workarounds because it is a scriptmodule. You can use the similar toolInvoke-Build. It is implementedas a script and avoids issues like these. It works finewith this build script:

Task Invoke-Deploy {    Import-Module ".\somefunctions.psm1"    Import-Module ".\morefunctions.psm1"    Set-Something #This is a function defined in morefunctions.psm1}

It outputs, as expected:

Build Invoke-Deploy ...\.build.ps1Task /Invoke-DeployGet-SomethingSet-SomethingDone /Invoke-Deploy 00:00:00.0150008Build succeeded. 1 tasks, 0 errors, 0 warnings 00:00:00.1450083

I ran into this today and got it to work.

In your module "morefunctions.psm1" you need to export the method you want like this:

 Export-ModuleMember -Function Set-Something

In your psake task, you need to prepend the module name in front of the method so PowerShell can find it:

Import-Module "morefunctions.psm1"morefunctions\Set-Something
