Powershell cannot bind ForegroundColor parameter

Question

I created the following Powershell script, which I hope to use to copy files to a network share.

function Copy-Deploy { param( [Parameter(Position=0,Mandatory=$true,HelpMessage="Path to scripts")] [Alias("pth")] [string]$ScriptPath, [Parameter(Position=1,Mandatory=$true,HelpMessage="Deployment script filename")] [Alias("dep")] [string]$PowershellDeploymentScript, [Parameter(Position=2,Mandatory=$true,HelpMessage="MSI filename")] [Alias("m")] [string]$MSI, [Parameter(Position=3,Mandatory=$true,HelpMessage="Filename of the MSBuild script (.btdfproj)")] [Alias("msb")] [string]$MSBuildScript, [Parameter(Position=4,HelpMessage="UNC path to target server folder")] [Alias("server")] [string]$TargetServerPath ) $ErrorActionPreference="Stop" #Step 1 : copy the MSI, .btdfproj script and control powershell script to the remote server Write-Host " Going to enter the mis script block" $misScript = { Write-Host " Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript Write-Host " Going to copy files" Write-Host " ScriptPath = $ScriptPath" Write-Host " PowershellDeploymentScript = $PowershellDeploymentScript" Write-Host " MSI = $MSI" Write-Host " MSBuildScript = $MSBuildScript" Write-Host " TargetServerPath = $TargetServerPath" Copy-Item -Path "$ScriptPath" + "$PowershellDeploymentScript" -Destination "$TargetServerPath" Copy-Item -Path "$ScriptPath" + "$MSI" -Destination "$TargetServerPath" Copy-Item -Path "$ScriptPath" + "$MSBuildScript" -Destination "$TargetServerPath" } Invoke-Command -scriptblock $misScript #Step2 : Execute the powershell script ExecuteBizTalkAppMSI.ps1 remotely on the target server #using syntax... invoke-command -computer $MachineName -command { $TargetServerPath + ExecuteBizTalkAppMSI.ps1 }" } 

I run this script from PowerShell ISE with the following line:

 Copy-Deploy "C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\" "ExecuteBizTalkAppMSI.ps1" "bin\debug\x.Int.MIS-3.0.0.msi" "x.Int.MIS.Deployment.btdfproj" "\\d-vasbiz01\BizTalkDeployment" 

Then I get the following error:

 Cannot bind parameter 'ForegroundColor'. Cannot convert value "C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\,ExecuteBizTalkAppMSI.ps1" to type "System.ConsoleColor" due to invalid enumeration values. Specify one of the following enumeration values and try again. The possible enumeration values are "Black, DarkBlue, DarkGreen, DarkCyan, DarkRed, DarkMagenta, DarkYellow, Gray, DarkGray, Blue, Green, Cyan, Red, Magenta, Yellow, White".At C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\CopyDeployScriptThenExecute.ps1:79 char:16 

Can someone tell me where I was wrong?

Answer 1

Line:

 Write-Host " Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript 

- a problem.

Write this:

 Write-Host (" Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript) 

-f taken as the -ForegroundColor parameter than the line format operator.

Answer 2

Wrap the message in parens. You can also use the variable extension and insert variables without using the -format operator (as you did in other calls to write):

 Write-Host " Path+Filename = $ScriptPath($PowershellDeploymentScript)"
