Can I get the default template to not require items to build? - tfs

The Items to build being added as a requirement in the default template appears to be doing so in the editor for Activities.BuildSettings? since I don't see it anywhere in the xaml. Or perhaps I could do something in the metadata collection to override the setting?
I want to run a custom task whether or not there is something being built with msbuild. What are my options?

Add a dummy project for TFS to build.

You can specify a targets file in the items to build. This targets file is using the msbuild syntax. In there you can specify what you want.

Modify setting in web.config on TFS build

Is it possible to modify a web.config file in one of my projects during a Team Foundation Server build? Inside of my web.config file I have two setting keys: VersionNumber and BuildNumber.
Is it possible to change the value of BuildNumber based on the ID of the build in TFS?
Since you're using TFS 2013 you have an easier option than the old way of modifying the workflow - Use PowerShell.
If you're using the build template TfvcTemplate.12.xaml (which is the new default in TFS 2013), then you have some extra build definition parameters you can set to specify Powershell scripts to run. This way you just write a little bit of powershell code that gets the TFS Build Number (from an environment variable), then finds your web.config file(s) and changes them.
There is a sample script published in the TFS Community Build Extensions project that will do something very similar that you could modify. It finds all AssemblyInfo.cs files, then uses RegEx to modify them to update the build number based on the TFS Build number.
See the sample PS script here: https://tfsbuildextensions.codeplex.com/SourceControl/latest#Scripts/ApplyVersionToAssemblies.ps1
See some docs on how to modify the build to run PowerShell here: http://msdn.microsoft.com/en-us/library/dn376353.aspx
The answer is yes, though it's non-trivial. I've done this in the past using two methods.
Method 1: Use CodeActivities and alter the TFS Build workflow XAML file to include the new CodeActivity as a workflow step.
Here's an article on creating custom workflows with custom code activities (it's a little dated but still relevant):
http://blogs.msdn.com/b/jimlamb/archive/2010/02/12/how-to-create-a-custom-workflow-activity-for-tfs-build-2010.aspx
Basically, you create a new object that inherits from CodeActivity, create properties for your inputs (BuildNumber,VersionNumber, TargetFile), perform your actions on the TargetFile and save it. Then you wire up this new DLL with your activity to the TFS Workflow XAML, injecting your activity in the desired build step (post-build & pre-package in your case I bet to ensure xml transforms are applied).
Method 2:
Tag the desired properties onto the MSBuild invocation inside the TFS XAML file so they are passed in to MSBuild and available for your to use as $(BuildNumber) and $(VersionNumber). Then you can use MSBuild tasks to inject the properties into the file at the right time.

getting TFS build definition metadata programmatically

I would like to get and then edit, programmatically, all of the process paramater metadata from a TFS build definition. Does anyone know how to do that? Thank you.
It depends on what you are after, many of the standard build properties can be set using the TFS Team Project Manager application, available on CodePlex.
Updated based on comments below.
You need to use the TFS API. There's a good intro here. If you need to set custom attributes, you can modify the ProcessParameters (and MSDN)
The ProcessParameters only has entries when the parameter is different to the Default. Try editing an existing build definition and changing a setting to a non-default value. The BuildSettings has the path to the Solution to be built and the configuration to use. This is probably where you want to edit the path to match your branch. Also you need to change the Workspace.Mappings property on the new build definition.

Can TFS build multiple solutions using "wildcards" or similar?

If I want to build multiple solutions in TFS Build I can add multiple SolutionToBuild elements to the Build Definition.
However, I want to specify a path to a folder, and then have TFS automatically find and build all solutions in this folder and subfolder, without me adding a SolutionToBuild element for each individual solution.
Is this possible?
Yes, this is possible, but not with the default build template as is. In the early stages of build execution, find a suitable build process trigger and include a step that finds your solutions in a supplied directory, and enter these solutions in the list of the SolutionToBuild variable. Then your script will continue as if you have added multiple SolutionToBuild elements.
No this is not possible. You can open the build default template and see how the projects/solutions to build are built with MSBuild.

TFS 2010 Build Definition

In the TFS 2010 build definition window, under “Process” there are two required items. They are “Configurations to build” and “Projects to build”. Under projects to build, it will allow me to enter something like:
$/TeamProject/Area1/Area2/*
However, this doesn’t seem to do what I expect. The build fails because it’s looking for:
$/TeamProject/Area1/Area2/Sources/*
What I am trying to achieve by this is to build all the solutions held under this area. For example, I have:
$/TeamProject/Area1/Area2/Solution1/Solution1.sln
$/TeamProject/Area1/Area2/Solution2/Solution2.sln
$/TeamProject/Area1/Area2/Solution3/Solution3.sln
There are many more solutions than this, which is why I’m looking for a way to build all solutions under the specified path recursively. Is there a way to do this in TFS 2010?
You can modify the process template. Expand it with the Matching files (I don't have the exact naming now) activity. Add a parameter that passes the information you set in the build defintion to the MachingFiles actvity. Then pass into the build solution activity instead of the argument that you enter in the build definition the files that is found by the MatchingFiles activity.
Now add a dummy solution in the build definition for the solution to build (it is not used anymore).
See the blog post series on the build customization for more information on customizing the build process template.
FWIW,
I've got: "configurations to build" blank
and under "projects to build" I've added my solutions via the ellipsis button
I would setup mappings for
$/TeamProject/Area1/Area2/Solution1/
$/TeamProject/Area1/Area2/Solution2/
$/TeamProject/Area1/Area2/Solution3/
Then in the build definitions enter the three projects to build
$/TeamProject/Area1/Area2/Solution1/Solution1.sln
$/TeamProject/Area1/Area2/Solution2/Solution2.sln
$/TeamProject/Area1/Area2/Solution3/Solution3.sln
You can leave the configurations to build as blank, or if you want to do a certain build you can set it to (for example) something like Debug|Mixed Platforms (check your Configuration Manager... for the solutions you are building to see what is valid)
Alternatively, you can just map the following (depending on how much you have in this folder, if you have Solutions 4+ that you don't want to trigger builds on, don't do it at this level)
$/TeamProject/Area1/Area2
And have one solution which contains the Solution1, Solution2 and Solution3, and build that instead.
By default building your Solution1 which is mapped to
$/TeamProject/Area1/Area2
On a build agent with a working directory that is going to looks something like:
$(SystemDrive)\Builds\$(BuildAgentId)\$(BuildDefinitionPath)
You'll end up with it being build under
C:\Builds\1\Solution1\Binaries
C:\Builds\1\Solution1\Sources
C:\Builds\1\Solution1\TestResults
Which is why you want to make sure that your OutDir's etc are all correct and not hard coded!
If you have a look while building, you'll see the build agent populating the Sources folder, and it should (if configured correctly) put all outputs into the Binaries folder (and then copy them to the Drop Folder configured under Build Defaults in TFS.

Building a set of specific projects in TFS

Does anybody know how can I configure TFS Build to build a set of projects in a solution instead?
The solution I have, has 16 projects but for one of my build definitions I want some of them to be compiled.
The easiest way in my opinion is to create a new solution file. There is nothing stopping you from having several solutions that reference the same projects (or some subset).
The other way is to create a new configuration. In Solution Explorer, rightclick the root node -> Configuration Manager. In addition to standard configs like "debug" or "release" you can create your own custom ones. For each combination of config + platform, you can use the checkboxes below to define which projects will be built and what settings they'll use.
Whatever you choose, you'd edit your TFSBuild.proj file to point to the desired solution and/or configuration. MSDN instructions: http://msdn.microsoft.com/en-us/library/bb399127.aspx
Once you create your build it will make a TFSBuild.proj file in source control (you can right click on the build in Team Explorer and select Configuration Folder to find it.
Open this file and find the tag that has "SolutionToBuild". That tag has sub tags for specifying targets. I think if you enter the projects you want to build in there (semicolon delimited) then it will just build those.
If you have not made your build yet then (as John Saunders said) you can specify the projects in the setup of the build. (After you have set it up you cannot do that again.
