Dropping a build in a fixed location - tfs

I have a build process that I've defined with a custom build process template, and I'm looking for some advice on how I can solve a problem I've run up against.
The build process (TFS 2012) is used to build the code that drives our load tests, and I have a separate process that needs to reference a specific path within the drop folder so that it is always using the latest version of the load test code. Automated load testing, pretty standard stuff.
However, I'm wondering if there is a way to get the TFS build to overwrite files it finds in the drop folder. Right now I have it set up to drop to a very specific folder, and not put anything that would change in the folder name (no build number, date, etc.). The thought is, this way the automated utilities that rely on those files have a fixed point to look at.
However, when I currently run the build it gives me error TF42064: The build number '<build>' already exists for build definition '<build>'.
Currently I have the build definition set up to only retain the latest build, because this process is specifically for those automated tools. We have other build processes that are fired for debugging/troubleshooting/logging purposes. Is there a way to get the build definition to overwrite the drop folder each time, or will I have to dig into the .XAML template file to have it delete the folder it finds before the build fires?

The way I approached this requirement was to start with the default template and let the build copy to the normal drop location which allows me to keep historical builds in the same way as all other builds.
Once the build has been completed I then copied to a single drop location from the standard drop location by extending the standard build template, the activity was added just before Check-In gated changes.
The steps involved were as follows:
Within SharedResourceScope:
Delete Unified Drop Location
Create Unified Drop Location
Copy Directory (source: BuildDetail.DropLocation)

By default TFS Build creates a new folder, using the unique build name/number, and drops the files there.
If you want to change this behaviour to overwrite files in a known location (instead of creating a new folder each build) you need to modify the build workflow/XAML (as #Oswald mentioned in the comments).

TFS Build Drop Folder

I'm currently working on a custom build process and have a problem with the understanding of drop folder. The process creates only some reports which we need for further development. We are using TFS/VS 2012.
What I actually need is either a folder on the buildserver where the Reports are going to be saved and accesable from everyone or on each team members local machine a drop folder. In my opinion the first solution should be better but is it possible, since I'm the only one out of my team which has Access to the buildserver.
If I select the UNC path to the drop folder on the buildserver can other People without Access to this Server use the "Open Drop Folder" button? And how do I even copy files to the drop folder? Is it enough to just do CopyDirectory? In the moment it always says: "This build did not produce any Outputs. The drop Location field is empty..."
I would be really glad if someone could help me.
The purpose of the drop folder is to copy the result of the build from the working folder of the agent and somewhere where it will not be changed by a later build. The share can be on the build server or on another server. No matter what you need to control the permissions to that folder so that whomever needs access has it. Otherwise the Open Drop Folder button will not work.
You can enable so that the build results are copied to the drop location upon build completion. This is a bit different whether you use Build vNext or XAML build. Since you are using TFS 2012, I guess that you are using XAML builds. Drop location is specified under the Build Defaults tab of the build definition.
The output folder from your build will be copied so assemblies, test results etc. will be copied to the drop location when enabled. If there is something extra that you want to be included in your drop, then copy it to the output folder or create it there directly.

TFS Build Queries for Non .NET supported files

We are using TFS for maintain file versions of our database.
We do not have any .NET application in our Source Control; only HTML and supported CSS files only.
Is it possible through TFS Build Automation process to create Zip package and Deploy the package to drop location?
Note: We Do not have any .NET project or solutions only need to deploy folder(with HTML and supported files) in zip format.
I somewhere read that TFS build definition compulsorily needs .SLN files to have build project.
We don't want to build anything or test anything
Just want to create zip and deploy same to drop location.
I have tried some tweaking of Build Definition.
But in New Build definition in process tab it asks me for Items to build, where my selection is restricted to .NET supported files only.
You will need to create a custom MSBuild project file (.proj) to perform the work that you need. You can test this file locally in the command line and then when it is ready, you can point the Build process at it.
This is a good starting point for you http://www.developerfusion.com/article/84411/customising-your-build-process-with-msbuild/
The MSBuild Community Tasks (https://github.com/loresoft/msbuildtasks) contains a Zip task which should make the job a lot easier.
Judging by your description, you are using 2010 or later. What I would do is to create a custom build template that does all of what you are looking for. If you start with default template obviously you would want to remove all of the compile and test activities and replace it with the zip and copy it to the binaries directory (From there it will be moved to the drop). You could do 1 of two things for the solution file requirement, create a fake solution file in the workspace and use that knowing it won't be compiled. Or you could, in the template, remove the Argument BuildSettings which is the object that contains the solution file and configurations.

TFS Build copies complete Repository for build

we have setup TFS Build for our project, but on every build the system copies the whole repository and then compiles our solution. How can we make sure TFS Build only downloads the files needed for the solution without having to cloak each un-needed directory manually ? Now it downloads over 2GIGs of data just to compile a project that is less then 100mb in size (source files). The other data are test databases and files that are not needed for the automatic build.
EDIT:
some further investigation let me to some keywords for searching. These posts are helping out:
Team Build - Get Workspace - get latest from specific paths, NOT everything
TFS Build and workspace
still investigating though. Any comments are welcome.
EDIT:
An option is to replace CreateWorkspace in the Build process definition with my own extended activity. I'm hoping to find out that somebody already did.. basically you would use the VersionControlServer object to download the necessary files instead of the whole workspace.
EDIT
There is currently no real good answer / solution to this. I gave some options and the people that responded gave some alternatives, but you can't easily change the TFS Build process to just download the data that is part of the solution instead of the whole repository. So be aware when you are building your repository.
You want to set the Build Definition mapping to only include the source you wish to compile. This means that you don't have to cloak any thing.
Edit Build Configuration
Click on Source Settings (VS 2012), Workspace (VS 2010)
An example specific mapping would look like this:
StatusSource Control Folder Build Agent Folder
Active$/Path/To/The/SolutionOrProjectFolder $(SourceDir)\
This will make the workspace for this build be limited to the solution that you wish to build. Therefore only AssemblyInfo files under that will be visible to your build activity.
If you cannot do this due to how your source control is setup, then I would suggest restructuring your folders within your Source Control.
If you have more than one Build Agent, you should limit the number of agents that the build definition can run against. That will stop multiple copies of the same source been downloaded on to the build machine(s).
The next part you have already answered in you question, by changing the "Clean Workspace" option in your Build Definition to None the build agent will only download the changesets between the current and last build.

The easiest way to test TFS2010 build template

I'm currently working on creating a build template for TFS2010 builds. However, I notice that I'm currently 'spamming' the source control with every change I make to the template (and lots more for all the fixes for those changes).
I wonder what the easiest way is to test the build templates I'm creating?
Is there a way to change the template file and custom activity dlls that doesn't involve checking them in?
I currently have a build controller and agent running on my developer machine, which I'm using to test the template (test = start a build and hope for less errors than last time).
Why is 'spamming' a problem? Anyway, I have a separate Team Project for doing this kind of work, that way I can check in to my hearts content without affecting the developers who need to have a stable build. once I've done my testing I check the template in to the team project(s) used by the developers.
I want to test my builds against the teams latest code-base without having to branch it over to a trial project.
Instead, I do the following:
Create a separate build definition called 'Infrastructure'
clone a production definition
Set the trigger on the Infrastructure build definition to manual.
Set the Infrastructure definitions permissions to allow only [Project]\Build group members to have full control of it.
keeps the notification of broken builds away from the bulk of the team).
Create a separate build process template, called 'Infrastructure.xaml'.
Point the Infrastructure build definition at the Infrastructure process template.
Now when I want to iterate on a new build feature for the team:
Check out the build process template I want to update, and lock it.
Copy the build process template I want to update overtop of the Infrastructure.xaml.
Add my build feature to the Infrastructure.xaml file, and check that in.
Use the Infrastructure build definition to test my changes.
Iterate over 3-4 until I get it right.
Complete the feature and have my changes verified by another Infrastructure team member.
Copy Infrastructure.xaml over the build process template I locked in (1) and check it in.
This still results in 'spam' in the TFS source control, but it keeps the build definition iteration out of the eyes of the team. My build process templates are located out of the main source tree (under the Build Process Templates folder, or in the branches themselves under a 'Core/Build' folder where no-one else on the team is typically paying any attention) so that the team is largely unaffected by it.
#d3r3kk: Why not just branch the template and merge changes back when ready instead of creating copies? That way you can preserve source history in a cleaner way as well.
Ideally, there should be a way to have a build process template that is in progress by having it on your local file system and pointing the build definition to it temporarily. Not sure if something like this exists in later versions of VS/TFS. I haven't seen it available via the UI anyway.

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.
