Creating a TFS Work Item from PowerShell
I came across a PowerShell script for creating TFS Work Items from Alan Stevens today. There are a couple more thougts and ideas I would add. Here is the output from my interactive PowerShell session (notice that I start with Alan's code to load the TFS assemblies. However, I begin to vary shortly after that.
|
>$key = Get-ItemProperty HKLM:\SOFTWARE\Microsoft\VisualStudio\8.0
>$dir = [string] (Get-ItemProperty $key.InstallDir)
>$dir += "PrivateAssemblies\"
>$lib = $dir + "Microsoft.TeamFoundation.WorkItemTracking.Client.dll"
>[Reflection.Assembly]::LoadFrom($lib)
>$lib = $dir + "Microsoft.TeamFoundation.Client.dll"
>[Reflection.Assembly]::LoadFrom($lib)
>$server="tfs"
>$NetCredentials=new-object System.Net.NetworkCredential ("Mark", "P@ssw0rd", "Michaelis")
> $tfs =new-object Microsoft.TeamFoundation.Client.TeamFoundationServer($server, $NetCredentials) |
To begin with I instantiate the TeamFoundationServer object rather than calling GetService(). This is because I want to change the network credentials that I use to connect to the server (see Buck Hodges post on this).
>$workItemStore = [Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore]
>$store=$tfs.GetService($workItemStore)
>$bug=$store.Projects["MSF for CMMI"].WorkItemTypes["Bug"].NewWorkItem()
>$bug.Title="The application isn't working"
>$bug.Save()
Exception calling "Save" with "0" argument(s): "TF26201: This work item has unsupported fields, or user does not have permissions." |
The next problem was that saving the bug results in an error. I am pretty sure it is not permissions since I specified the credentials explicitly. This leaves the unsupported fields option (whatever that means). I check the Fields property and determine what the required fields are. After setting these fields I am able to store the bug. A non-zero ID and the revision number are just a few properties that verify the work item was successfully stored.

Just to make sure, I run a query for all active bugs to verify that mine is there.

One PowerShell question I couldn't find the answer on, is how do I enter a password without displaying it on the screen. The way RunAs works for example.
