TFS-2017 - Add a step to enter Username and password - powershell

Question

I have a build that creates .zip package and projectName.SetParameters.xml i want to overide the parameters in The projectName.SetParameters.xml file with my script
I have a powershell script with Mandotary parameters, I want the user to input their username and password before they can deploy to IIS in TFS i was following this guide link
UPDATE: The REalese build works but it doesn't ask the user to input the username and password, Do i have to set them manually inside the argument box on the Powershell step?
In my TFS I Have a powershell step i added the argument -paramsFilePath C:/somepath/.../.../projectName.SetParameters.xml
param(
[string]$paramsFilePath,
[Parameter(Mandatory=$true)]
[string]$username,
[Parameter(Mandatory=$true)]
$password
)
Write-Verbose -Verbose "Entering script setParameters.ps1"
Write-Verbose -Verbose ("Path to Parameters: {0}" -f $paramsFilePath)
# get the environment variables
$vars = Get-ChildItem -path env:*
# read in the setParameters file
$contents = Get-Content -Path $paramsFilePath
# perform a regex replacement
$newContents = "";
$contents | % {
$line = $_
if ($_ -match "__Username__") {
$setting = Get-ChildItem -path env:* | ? { $_.Name -eq $Matches[1] }
if ($setting) {
Write-Verbose -Verbose ("Replacing key {0} with value from environment" -f $username.Name)
$line = $_ -replace "__Username__", $username.Value
}
}
$newContents = $line
}
Write-Verbose -Verbose "Overwriting SetParameters file with new values"
Set-Content $paramsFilePath -Value $newContents
Write-Verbose -Verbose "Exiting script setParameters.ps1"
Here is my Parameters.xml code
<!--?xml version="1.0" encoding="utf-8" ?-->
<parameters>
<parameter name="machineURL" description="Please enter the name of the Environment" defaultvalue="_UrlValue_" tags="">
<parameterentry kind="XmlFile" scope="\\web.config$" match="/configuration/appSettings/add[#key='machineURL']/#value">
</parameterentry>
</parameter>
<parameter name="username" description="Please enter the username" defaultvalue="__UserName__" tags="">

<parameterentry kind="XmlFile" scope="\\web.config$" match="/configuration/appSettings/add[#key='password']/#value">
</parameterentry>
</parameter>
</parameters>

The PowerShell execution in TFS Build and Release is only in non-interactive mode possible. The build and release process will only streams the execution result to the build console.
You have to create a variable with the username. For the password you should use hidden variable:
Yes you have to place the arguments inside the argument box of the
PowerShell step
Note: The password field seems secure and not readable but it is not really hard to read the content of a hidden variable.
Create the variables and set the values. After that you can use this command line parameter in the PowerShell step argument box.
-paramsFilePath $(paramsFilePath) -username $(username) -password $(password)
