TFS Build Copy to Versioned Folder - tfs

I'm currently looking at a TFS build server setup & I was trying to set up a process whereby I can set up a build template to build to a folder based on the version number of a .NET assembly that's part of the build (As per the assemblyinfo.cs file). I've got it building to the standard looking folder ("Release_20130502.1"), but that's not exactly useful in 4 months time when we want to find the build for the v1.1.0 release.
Basically I want to make a special build template which will create a major release, and I'd like the folders it makes to be more noticable as versions rather than timestamps. I'm also hoping to automatically label the release as that version too. I know how to copy the files & make labels, but I'm not sure how to get at the version numbers.
I'd also love if I could get this into the Build Name recorded in TFS somehow but I suspect that might be a bit optimistic.
Does anyone have any idea how to do this (Or alternatively any other technique that'll get me easily recognizable release version builds)?

Take a look at build number format property for build definitions this is used to generate the build number and in turn the build folder during build and label in sourcecontrol if its enabled, you can modify this manualy to pass desired build number. The mentioned drop folder can be manually given as well. And you can always copy the folder after build by hand.
You can use revision variable to create something that works similiar to what you want, Revision number gets incremented if there is build with same name in system
Format: Release v1.$(Rev).0 - this would give you Release v1.1.0, Release v1.2.0, ... on each build
You will have to customize build definition with custom activity for your defined goal to work without manual interaction. However with details you have provided this approach has issues - each project has its own assembly info - which one do you use, what if they are different? This should get you started.

You can take a look at these may find something useful

It all comes down how often do these build take place, if its week or more then doing it by hand is perfecly valid aproach in my book.

Displaying in Jenkins content from workspace text file in build screen

I have a Jenkins job that stores artifacts as a post-build action. Within these artifacts is a text file that tells which version of the software has been built. Is it somehow possible in a Jenkins project to get access to this text file and displaying its contents somewhere on the Jenkins build page somehow? This way the build manager would instantly see what software version this archived artifact contains. Thanks!
There are more advanced ways with GroovyScript, but I can suggest something like this:
Use Description Setter plugin. It uses RegEx to look at the console output (build log) for a pattern and sets the description (as seen in screenshot) accordingly.
If you don't have the version already printed in console log, you can print it out with either
cat filename (Linux) or type filename (Windows). No need to store a version text file as an artifact (unless you need it for other purposes)
To answer your question directly, in order to add text to actual build page, you can use Groovy Postbuild plugin, something like this:
def workspace = manager.build.getEnvVars()["WORKSPACE"]
String fileContents = new File('${workspace}/filename.txt').text
manager.createSummary("folder.gif").appendText("${fileContents }")
The plugin page has a lot of examples.
I got a revised proposal. Since all you really want is to include a semantic versioning information in your displayed build name and/or description, there is a simpler way to do this.
First of all I have stumbled upon a plugin that does the extraction of your version from the Maven or SBT build process quite nicely - the Semantic Versioning Plugin. This does what is advertised - extracting the version from POM or whatever and including this as a file and a variable in your build process. So you have the freedom to use both, either include the file in your build process and do what you heart wishes AND/OR use the variable to affect the build flow in Jenkins. Now, because this plugin still have couple of bugs I would like to point you for now to my own build of this plugin with fixes already in that can be obtained from here. I will take my own version down the moment that all fixes will be merged to the official plugin...
Then let's start with the name. As suggested previously the best way to do so is to use the Build Name Setter plugin. In order to use both plugins to set up a name for your build navigate to the configuration of the project and find an option named "Determine Semantic Version for project" in there, activate it and either use the default name of the variable or provide your own. When you're down scroll down a little bit to the option named "Set Build Name" and activate it. By default you will see the regular build naming convention there - #${BUILD_NUMBER}. You can use that variable as well as any other provided by any plugin, but in this specific case you need to use the environment variable that you have named above, i.e.:
#${BUILD_NUMBER} - ${ENV,var="SEMANTIC_VERSION"}
This will set the name of every build to something more meaningful, so in this case it may result in #76 - 0.0.76-SNAPSHOT. Obviously you're free to experiment on your own to tailor the name of the build to specific format you desire. Keep in mind that it might break your page flow a little bit since the name will be longer than usually, therefore it will push that table with latest builds on the left side of the screen as well it will affect your dashboard.
Now, in order to customize your build information further you might want to take a look at Description Setter Plugin as well. Personally, since I have started to investigate this case further, I use the combination of both at this time. You can use the same token expansion as the one listed above, the big difference is that you will need to create/maintain a file that will be used to create the description. What you will include in this description is only limited by all the variables or token published by Jenkins itself or any of the installed plugins (take a look here). Personally I am listing some information gathered from different places as well as some additional stuff created/provided by Maven during the build process. So it's pretty handy.
Both plugins mentioned above (Build Name Setter and Description Setter) can use other sources of information to build the name and description - it can be properties files, etc. For example one can use Job Exporter Plugin to drop a properties files to read all possible information about the build itself in the form of, as example:
${PROPFILE,file="hudsonBuild.properties",property="build.user.name"}
In this case this will resolve to user name of the user who have triggered the build.
Again, any variable visible to Token Macro plugin can be used.

Does TFS 2010 Team Build suppress checkins during the build, even if part of the build?

I have created some custom CodeActivity-derived clases which:
successfully check an assembly info file, GlobalAssemblyInfo.cs,
changes the value of AssemblyFileVersion,
and then checks it back in, returning the change set value.
I based some of this work on Ewald Hofman's wonderful blog Customize Team Build 2010 – Part 5: Increase AssemblyVersion
The Problem:
Later in the build, one of my projects in this solution uses the version number to create a subdirectory by getting the version number from the newly built assembly. The problem is the subdirectory always lags behind in the version number. I've noticed that when I test the build definition based on the BuildProcessTemplate, that my included change sets never include the GlobalAssemblyInfo from that build.
The build log tells me that steps 1, 2, and 3 all work. It also tells me that Associated Change Sets in the summary don't include the change set number in step 3. Does anyone know how I can work around this problem?
I found the answer to this question experimentally. As soon as a build is started, that point in the version tree is used for the associated change sets. Since I am checking out and checking in a file after that point, it is not part of the build. I got around this problem by calling my GetLatest activity after the Get All (specific), as seen in the DefaultTemplate. It's accomplishes the goal of getting my changed version number used in the assemblies.

Automatic Versioning with Team Foundation Server 2012; Increment Only on Changed Assembly

I've been tasked with setting up a new Team Foundation/Build server at my company, with which we'll be starting a new project. Nobody here currently has experience with TFS, so I'm learning all of this on my own. Everything is working so far; The server's been set up, the Repository and Team Project has been created, the Build Server has been created, and I've created a simple hello world application to verify the source control and Continuous Integration builds (on the build server) run properly.
However, I'm having a problem setting up the automatic versioning. I've installed the TfsVersioning project, and it's working fine; I'm able to define a format for my assembly versions. I haven't yet decided what format I'll use; probably something like Major.Minor.Changeset.Revision (I'm aware of the potential problem regarding using the changeset number in the assembly version, so I may decide to switch to Major.Minor.Julian.Revision before we begin development).
The problem:
I don't want assemblies to have new file versions if their source code has NOT changed since the last build. With a continuous Integration build this isn't a problem, as the build server will only grab the source files that have changed, causing an incremental build which produces only updated modules; the existing unchanged modules won't be built, so their version will remain unchanged.
If I set up a nightly build, I'll want to clean the workspace and perform a Build-All. However, this means that ALL assemblies will have new version (assuming the Assembly File Version includes the build number).
A solution?
This has prompted me to consider using the latest changeset number in the Assembly File Version. This way, if nothing has been committed between two successive Build-Alls, the versions won't be incremented. However, this would mean that a change and commit to a single file would force a version increment on ALL assemblies.
I'm looking for one of two things:
A way to only increment Assembly Version Numbers if their source/dependencies have changed since the last build. Successive Build-Alls should not cause changes in version numbers.
OR
A way for testers and non-developers to be able to tell version W.X.Y.Z and version W.X.Y.Z+1 of assembly 'Foo' are identical, even though they have differing file versions.
I've probably read about 20 articles on the subject, and nobody (except this guy) seem to address the issue. If what I'm asking for isn't common practice in the Team Foundation ALM, how do I address the second bullet point above?
Thanks for your time!
This is something I did in the past. The solution has two critical points:
You must use an incremental build, i.e. Clean Workspace = None
The change to AssemblyInfo.cs must be computed at each project
This latter is the most complex and I will just draft the solution here.
In the custom MSBuild properties use CustomAfterMicrosoftCommonTargets to inject an hook in normal Visual Studio compile
/property:CustomAfterMicrosoftCommonTargets=custom.proj
Also forward a value for the version
/property:BuildNumber=1.2.3.4
In custom.proj redefine the target BeforeCompile to something similar
<Target Name="BeforeCompile"
Inputs="$(MSBuildAllProjects);
#(Compile);
#(_CoreCompileResourceInputs);
$(ApplicationIcon);
$(AssemblyOriginatorKeyFile);
#(ReferencePath);
#(CompiledLicenseFile);
#(EmbeddedDocumentation);
$(Win32Resource);
$(Win32Manifest);
#(CustomAdditionalCompileInputs)"
Outputs="#(DocFileItem);
#(IntermediateAssembly);
#(_DebugSymbolsIntermediatePath);
$(NonExistentFile);
#(CustomAdditionalCompileOutputs)"
Condition="'$(BuildNumber)'!=''">
<Message Text="*TRACE* BuildNumber: $(BuildNumber)"/>
<MyTasksThatReplaceAssemblyVersion
BuildNumber="$(BuildNumber)"
File="$(MSBuildProjectDirectory)\Properties\AssemblyInfo.cs"/>
</Target>
You need to have a task for replacing the AssemblyFileVersion in the AssemblyInfo.cs source. MSBuild Extension Pack has an AssemblyInfo task for this purpose.
I posted the full details at my blog here, here and here.

Rebuilding historical builds through TFS with version numbers

I have automatic build numbering setup, based on build date/name, using approach proposed by John Robbins from Wintellect described here. So the version/resource file is automatically created on build time but not checked-in.
I wonder how to approach a problem of rebuilding historical versions (based on labels) and having the original build number/name in them. Is it possible to detect 'GetVersion' parameter of MSBuild and try to recreate the original build name from it?
Is it a sane approach anyway? What alternatives do you see?
It's not easy to build a specific changeset (though possible, if you pass the changeset number into your build script and modify the "Get Latest" portion of the build).
However, one easier way of handling this is to create a branch of your code. You can branch at a specific date or changeset, which will create a copy of code from that point in time. Your build scripts can then be pointed at this code.
With respect to your versioning problem: you may find that the only sensible way to do this is to hardcode the required version number. My understanding of your version numbering strategy is that it doesn't relate to anything you can derive from the source (such as the changeset number, date, or file content), and it isn't checked in - so re-calculating it will be pretty complicated!
You ask question Rebuilding historical builds but it actually Rebuilding historical change Set or label, I know what you mean but I am trying to tell you what I need to say, so I don't see that we need to build a label with the specific name the label or change set can has many build as needed and since we use the date and time in the build number it will more realistic to has the current time and date the build was taken instead of old one

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.
