I'm struggling to find a solution for this issue.
I have a solution (VS2008) that contains around 50 projects (C#).
The inter-project dependencies are added as project-reference (and not by referncing a DLL).
Also, the dependencies inside VS is set correctly in the solution settings dialog.
The problem is, when building the solution from MSBUILD (command line) on our CI server, msbuild will build the projects in what seems to be the order that they're laid out in the solution file, and not according to the dependencies.
I've found numerous references for this on the web, with no solution...
What can i do in order to build the solution correctly with msbuild from command line ?
This can be due an invalid build order inside your solution. You can change the build order without removing and re-adding the project. In Solution Explorer, right-click the solution name and select Project Build Order. You will be able to specify the build order of your projects so it should work in msbuild. This commonly happens if inside VS you have cached the DLL's during development. To verify if it works, remove all obj and bin folders before changing the build order and running the build.

I'm facing a weird issue while trying to build using MSBuild.
I'm using MSBuild to build a solution file with /m (parallel build) and BuildProjectReferences set to true.
Suppose I have A.vcxproj and B.vcxproj in the sln file with B having a project reference to A.
What happens is A project starts to build first and while its in the middle of compiling, B project starts to build in another process (since parallel builds) and it would invoke building A.
Now this causes a race condition because we have two processes trying to build the same project A and I would see access issues.
Ideally MSBuild should not invoke building B if A hasnt finished building or if it does invoke B then detect that A is still building and wait for it to finish.
None of this happens. Also, this happens only with MSBuild - doesnt happen if I try to build the solution file from VS2015 IDE.
Any idea why MSBuild behaves this way?
Finally found the solution to my problem
MSBuild expects that the project dependencies be added in two ways
1. In the vcxproj itself, add all the dependent projectreference
2. In the sln file too, define the projectdependencies.
The following VS blog actually states the opposite- For example - https://blogs.msdn.microsoft.com/vcblog/2010/02/16/project-settings-changes-with-vs2010/ states that projectdependencies and projectreference are analogous and use only one specifically projectreferences.
This may be true when you build using VS IDE but not for MSBuild. It needs the project dependencies to be defined on both ProjectReference and ProjectDependencies.
Hope this helps anyone who hit into the same issue as mine.
I want to build a project with a particular named Build Configuration, let's call it Conf-A.
This is running as an MSBuild step on TeamCity. When the build runs, it spits out:
The OutputPath property is not set for project ... You may be seeing this message because you are trying to build a project without a solution file, and have specified a non-default Configuration or Platform that doesn't exist for this project.
This project is part of a hulking great solution we load on our dev machines.
The error makes sense for my situation, since I'm building just the proj file, but I don't want to use the solution file since I'm trying break-up this monolithic app.
I want the build-server to treat this project as it's own component, even if for the moment it is part of a solution and has references to other projects (assemblies) in the solution.
Must I build this via a solution file?
I could potentially copy the solution file and prune off all the other projects that are not required, but that's more complexity.
(Maybe the error is a red-herring).
you dont need to build a sln. Its like the error says. You just havent specified a value for the variable OutputPath in your msbuild. You can add it to your files or you can pass it in at the cmd line - msbuild someproj.proj /p:OutputPath=C:\notallovermydrive
I have a project file that should build another solution. I tried using the MSBuild task for this, like this:
<MSBuild Projects="MySolution.sln" Properties="Configuration=$(Configuration)"/>
I tried a lot of variants, like supplying hardcoded configuration, target Rebuild and so on. Building reports an error when I pass a wrong solution name, non-existing configuration or target and so on, so it definitely loads the solution and the project files. It exits relatively fast though and produces no output. According to documentation and examples, this should work though. I also tried passing an ItemGroup for the project, including project-specific properties as suggested by examples or in MSBuild - How to build a .NET solution file (in an XML task script) from pre-written command line commands , but that does not work either. It runs without error but no output.
When passing a list of project files instead (or a single project file), it builds correctly, but the problem is that dependencies between the projects are not properly resolved. At the end, I have to supply all project files in the solution and add them to the list, which is what I want to avoid.
So, why does solution building not work, even though it should? What is wrong here?
Is this a .net project? If so you probably need to pass in a platform as well as a configuration.
<MSBuild
Projects="MySolution.sln"
Targets="build"
Properties="Configuration=$(Configuration);Platform=$(Platform)" />
If the project just contains web sites and libraries then the platform should be Any CPU if your solution just contains executables then x86 or x64 or if it's a mixture of different types of platform then you can use mixed platforms
To check what are available open the solution in Visual Studio, right click on the solution in solution explorer and select "Configuration Manager" you'll then have a drop down for "Active Solution Platforms"
We have a very large solution (some 300+) projects and we are trying to build it via MSBuild on TFS2010.
We can build it via MSBuild on all out development machines, and are in the process of adopting TFS.
The structure of our code is like so:
bin\Client
bin\Server
Framework\ClientFramework.csproj
Modules\Module1\Project1
Modules\Module2\Project2
etc.
Each project has a relative OutputPath which builds the code to the bin Client or Server directory. So for example, Project1.csproj has an OutputPath of "..\..\bin\Client".
We seem to be having a problem that in TFS MSBuild the OutDir is set to a Fixed Path:
C:\Builds\MyProject\Binaries\
So things are getting confusing when resolving the relative OutputPath on top of the OutDir
ClientFramework goes to C:\Builds\MyProject\Binaries\..\bin\Client
Project1 goes to C:\Builds\MyProject\Binaries\..\..\bin\Client
etc.
We also have some Post build events that copy some 3rd Party dll's to the bin folders, these paths cannot be resolved properly either.
I think the solution we are after is to build everything to our existing bin\Client, bin\Server structure and then move the Folders from bin to Binaries.
Any ideas on how to accomplish this or how we should be working, are appreciated, but updating our existing projects might prove problematic, as it all works with VS, developer command line builds and with CC.net.
Since this is first link that pops up with a Google search of "TFS OutDir", I must provide a newer solution. I spent an entire day playing around with OutDir, OutputPath, and overriding them with TeamBuildOutDir. A better solution is to set the MSBuild property GenerateProjectSpecificOutputFolder. It comes with .NET 4.5. More info here: http://blog.codeassassin.com/2012/05/10/override-the-tfs-team-build-outdir-property-net-4-5/
I found the answer on MSDN : http://msdn.microsoft.com/en-us/library/ff977206.aspx
Ok, so I've got a somewhat complicated problem with my build environment that I'm trying to deal with.
I have a solution file that contains multiple C# projects which is built by a NAnt script calling MSBuild - passing MSBuild the name of the solution file and a path to copy the binaries to. This is because I want my automated build environment (CruiseControl.Net) to create a folder named after the revision of each build - this way I can easily go back to previous binaries for any reason.
So idealy I have a folder layout like this
c:\build\nightly\rev1
c:\build\nightly\rev2
c:\build\nightly\rev3
...
c:\build\nightly\rev10
etc.
The problem that's arisen is I recently added the latest version of the Unity IoC container to my project, checking it directly out of MS's online SVN repository. What's happening is I have a Silverlight 3 project that references the Silverlight version of Unity but I also have other projects (namely my Unit testing project) that reference the standard (non-Silverlight) version of Unity.
So what happens is since MSBuild is dumping everything into one single folder the Silverlight version of the Unity assembly is overwriting the non-Silverlight version because they have the exact same assembly file name.
Then when CruistControl runs my unit tests they fail because they don't have the proper dependencies available anymore (they try to load the Silverlight specific Unity assembly which obviously doesn't work).
So what I want to do is:
keep my desired output directory
structure (folder\revision)
I don't want to have to manually edit
every single proj file I have as this
is error prone when adding new
projects to the solution
Idealy I would like MSBuild to put everything into a folder structure similar to this:
nightly\revision1\project1
nightly\revision1\project2
nightly\revision1\project3
...
nightly\revision2\project1
nightly\revision2\project2
nightly\revision2\project3
etc
I can't modify the Unity project to give it a different file name because it comes from another SVN repository I cannot commit changes to. I found a similar question posted here and the suggested solution was to use a "master" MSBuild file that used a custom task to extract all the project file names out of the solution then loop over each one building them. I tried that but it doesn't build them in the order of their dependencies, so it fails for my project.
Help?
Firstly I would always have the build server delete the old working copy and check out a fresh copy to avoid any problems with stale artifacts from the previous build.
Next I would have nant or msbuild build the solutions as before with the artifacts from each build going to their local working output folders.
After that I'd move the artifacts from their working paths to their output paths, this shouldn't require digging through the project files since you can just tell msbuild/nant to copy working\project1\bin\release\**\*.* to artifacts\project1\.
The script that does this should ideally be stored along with the source with the main file, e.g. build.nant or build.proj in top level of the trunk.
For third party libraries I would simple include the DLLs directory in your repository. Nothing worse than writing some code and having a third party dependency break your build because of changes on their end.
Simply document the versions of the libraries you are using, and if you must update them, you'll have a better sense of what breaks the build before you even check it in.
Also, doesn't CC.Net automatically handle the providing of releases based on revision? I'm using TeamCity and it keeps a copy of the artifacts of every build.
I highly recommend reading JP Boodhoo's Automating Builds with NAnt blog series. That's been my starting point and have made lots of changes for my own taste. I also highly recommend checking out the builds of many open sources projects for examples. I've learned a lot from the builds of the Castle/Nhibernate/Rhino-Tools stack.
