Question about Invoke-Plaster and -Passthru

[LaurentDardenne]

I use the latest build, and i test the passthru parameter of Invoke-Plaster :

$Result=invoke-plaster "C:\Program Files\WindowsPowerShell\Modules\plaster\1.0.2\Templates\NewPowerShellScriptModule\" -DestinationPath C:\temp\TestManifest -PassThru
$Result

The result is correct :

Destination path: C:\temp\TestManifest


TemplatePath    : C:\Program Files\WindowsPowerShell\Modules\plaster\1.0.2\Templates\NewPowerShellScriptModule\
DestinationPath : C:\temp\TestManifest
Success         : True
TemplateType    : Project
CreatedFiles    : {C:\temp\TestManifest\test.psd1, C:\temp\TestManifest\test.psm1}
UpdatedFiles    : {}
MissingModules  : {}
OpenFiles       : {C:\temp\TestManifest\test.psd1, C:\temp\TestManifest\test.psm1}

Now i lock the test.psm1 file and call Invoke-Plaster again :

Function Lock-File{
  param([string] $Path)

  New-Object System.IO.FileStream($Path, 
                                  [System.IO.FileMode]::Open, 
                                  [System.IO.FileAccess]::ReadWrite, 
                                  [System.IO.FileShare]::None)
} #Lock-File

Remove-Variable Result
.{
 try {
    $Filename="C:\temp\TestManifest\test.psm1"
    $TestLockFile= Lock-File $FileName
    $Result=invoke-plaster "C:\Program Files\WindowsPowerShell\Modules\plaster\1.0.2\Templates\NewPowerShellScriptModule\" -DestinationPath C:\temp\TestManifest -PassThru
  } finally {
   $TestLockFile.Close()
  }
}

The Result variable is not created.

Is the correct behavior in this case or all exceptions must trapped when -Passtrhu is set ?

[LaurentDardenne]

The Result variable contains two objects: a string and a PsCustomObject.

And the MissingModules property contains a string, A hashtable @{Name;Version} avoid text parsing if I want install this modules.
