I am using the MSBuild runner in Team city to build and deploy my project to a staging environment. Everything works perfectly except for the fact that it keeps removing my repository folder located in the root of the project.
In Visual Studio 2010 there is a check box in the publish profile dialog that says "Leave extra files on destination (do not delete)"
Is there a way to accomplish the same thing with MSBuild?
<Target Name="Deploy" DependsOnTargets="Build;Test">
<MSBuild Projects="MyProject.sln" Properties="Configuration=$(Configuration); username=username; password=password; DeployOnBuild=True; DeployTarget=MSDeployPublish; MSDeployPublishMethod=WMSVC; MSDeployServiceUrl=https://DEVWEB01:8172/MsDeploy.axd; DeployIISAppPath=MyProject.$(Configuration); AllowUntrustedCertificate=True;"/>
</Target>
Found the answer!
All you need to do is add the following property to the Properties attribute:
SkipExtraFilesOnServer=True;

My solution has 5 projects and tfs build is working fine. Issue I am having is when I set to deploy from tfs on successful build. Its looking for publish profile in wrong project rather than my startup project. Please Help.
ScreenShot
Update:- So I was able to eventually find what was causing the issue during my build and publish in tfs. Each of the projects that were added in my solution were web applications. And Each of the project had in .csproj file these settings <Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />
<Target Name="MvcBuildViews" AfterTargets="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
<AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" />
</Target>. Once I have commented out these in my other applications, the tfs build/publish using my publish profile was not looking for config file that I mentioned in my publish profile. Thanks for your help Patrick.
Suggest you first manually remote to your build agent and double check if there are corresponding DEVAPP1DEBUG.pubxml file located at the path on the build agent.
According to your description, maybe there are something wrong in your build artifacts for deployment. Suggest you try this way, looking into the TFS options for Build Definitions and when you have to select a template for the definition, you can see two options Build and Deployment, try with the Deployment option :
and by default in the MSBuild Arguments the parameter is :/p:OutDir="$(build.binariesdirectory)\\"
In that folder you should have everything need for the deployment.
I'm using Visual Studio 2017 and have a solution with several web projects and webjob projects.
There are some files that I want to include when running locally in the development environment that I want to exclude from being deployed as part of a web publishing package.
I'm attempting to use the process described here http://sedodream.com/2010/05/01/WebDeploymentToolMSDeployBuildPackageIncludingExtraFilesOrExcludingSpecificFiles.aspx and elsewhere, which is:
<ItemGroup>
<ExcludeFromPackageFiles Include="connectionstrings.config">
<FromTarget>Project</FromTarget>
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</ExcludeFromPackageFiles>
</ItemGroup>
This works perfectly for my web projects - meaning that when building the connectionstrings.config file is copied to my bin\ directory and not included as part of the web deployment package - whereas when implemented in my webjob projects the file is copied to my bin\ directory but also included in the deployment package.
In the msbuild output I see:
Copying file from "C:\Users\me\Documents\Projects\myapp\myapp\webjob1\connectionstrings.config" to "bin\ProdBuildCfg\connectionstrings.config".
which is what I want because it allows me to run/debug locally, and also:
Copying C:\Users\me\Documents\Projects\myapp\myapp\webjob1\bin\ProdBuildCfg\connectionstrings.config to obj\ProdBuildCfg\Package\PackageTmp\app_data\jobs\continuous\webjob1\connectionstrings.config.
which demonstrates the problem - connectionstrings.config is still being copied to the package directory for subsequent publishing/deployment.
The process described in the above article and others applies to web projects, and they indicate you should place the <ItemGroup> under the
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" />
line of the project file. Webjob projects don't include that line but rather have something resembling:
<Import Project="..\packages\Microsoft.Web.WebJobs.Publish.1.0.13\tools\webjobs.targets" Condition="Exists('..\packages\Microsoft.Web.WebJobs.Publish.1.0.13\tools\webjobs.targets')" />
I suspect the problem relates to targets - either my project file doesn't include the proper <Import Project="...*.targets')" /> line or I'm not at the right spot in the file.
Next I tried the method mentioned here How do I include webjob files while debugging locally but exclude when publishing a web package?:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<ExcludeFilesFromDeployment>connectionstrings.config</ExcludeFilesFromDeployment>
</PropertyGroup>
I have the connectionstrings.config Build Action set to None and Copy to output directory set to Always (my understanding is that action that results from the Copy to output directory setting is distinctly different from the actions associated with packaging/deployment). Same result. (I've ensured I'm in the right <PropertyGroup> for my build configuration.
Note: I'm deploying either by right-clicking the project in VS and selecting "Publish as Azure webjob" or using an msbuild command to publish like msbuild myproj.csproj /p:DeployOnBuild=true /p:Configuration=Release /p:PublishProfile="Prod" /p:VisualStudioVersion=15.0 /p:Password=
How do I include webjob files while debugging locally but exclude when publishing a web package?
To my knowledge, if you do not want to publish any file, you just need to set the file property to "copy to output directory as DO NOT COPY". This way when you will package the application that particular file will not be part of package and will never be on Azure.
Update:
Unfortunately that setting prevents the file from being copied to the
output directory which means I can’t run or debug locally.
When you debugging the project, you can set the "copy to output directory" as "Copy always". When you want to deploy the project, you can manually clean the build and change the value to DO NOT COPY.
If you do not want to do all those manually, I would like provide you a workaround, hope this can help you.
To accomplish this, unload your project. Then at the very end of the project , just before the end-tag, place below scripts:
<Target Name="ExcludeFileFromPackage" BeforeTargets="PipelineCopyAllFilesToOneFolderForMsdeploy">
<Message Text="Delete the connectionstrings.config from Obj folder to exculde this file in the package directory" />
<Delete Files="$(ProjectDir)obj\Release\Package\PackageTmp\connectionstrings.config" />
</Target>
With this target, VS/MSBuild will delete the connectionstrings.config from the obj folder before publish the project as package.
I use SlowCheetah to transform my app.configs. I have a multi-project solution where one of the projects executes a post-build event where the output of the bin is copied elsewhere. I've found that SlowCheetah does it's transforms after the post-build event, so the app.config I'm copying is the pre-transformed version.
Does anyone have a suggestion of how I can execute my copy after the SlowCheetah transforms? Is this going to require that I write a custom build task?
If you are using msbuild 4.0 for building your projects - you can hook to slowcheetah targets with new AfterTargets BeforeTargets attributes.
I dont know what exactly target name you want to hook after but this code could gave you base concept how to do this
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="Some_Target_Name" AfterTargets="TransformAllFiles" >
<Message Text="= Script here will run after SlowCheetah TransformAllFiles ="/>
</Target>
<Project>
Edited: I installed SlowCheetah and found that AfterTargets attribute should be "TransformAllFiles".
Just set up your target dependency AfterTargets="TransformAllFiles"
Alexey's answer leads to the correct solution but here it is in full:
Right-click your project and select Unload Project
Now right-click the project and select Edit [your project name].csproj
Scroll to the bottom and uncomment the target named AfterBuild and add this attribute AfterTargets="TransformAllFiles"
Move your post build actions into this target using the Exec command:
An example:
<Target Name="AfterBuild" AfterTargets="TransformAllFiles">
<Exec Command="ECHO Hello PostBuild World!" />
</Target>
I have bumped into this problem too... decided to update to latest version of SlowCheetah (current 2.5.8), and this problem appears to have been fixed! No more problems using post-build events to deploy a project with transformed XML!
After the NuGet package upgrade process, I had a strange issue, though... transforms were no longer happening. Editing the project like Naeem Sarfraz suggested, I have found that the SlowCheetah's PropertyGroup section was placed at the end of the .csproj.
It was just a matter of moving it to the top, near the other PropertyGroup sections, and now it works like a charm!
If you need to copy/move other .config files (other than web.config) around after the build before publishing here is how it can be done with Visual Studio 2013 (I didn't test it on earlier versions). This section can be added at the end of the .csproj file right before the closing tag </Project> and it'll be fired just before MSDeploy starts the Publishing process.
<Target Name="MoveConfigFile" BeforeTargets="MSDeployPublish">
<Move
SourceFiles="$(IntermediateOutputPath)Package\PackageTmp\ThirdPartyApp.config"
DestinationFolder="$(IntermediateOutputPath)Package\PackageTmp\bin"
OverwriteReadOnlyFiles="true"
/>
</Target>
The company I work for purchased a third party product that needs to have a .config files in the bin folder along with its assembly in order to work.
At the same time we need to process the product's .config file and be able to move it to the bin folder after transformations.
The $(IntermediateOutputPath)Package\PackageTmp folder contains the whole application that will be copied over the target server.
Folks,
In a nutshell, I want to replicate this dialog:
It's a Visual Studio 2010 ASP.Net MVC project. If I execute this command, I get all the files I want, including the transformed web.configs in the "C:\ToDeploy" directory.
I want to replicate this on the command line so I can use it for a QA environment build.
I've seen various articles on how to do this on the command line for Remote Deploys, but I just want to do it for File System deploys.
I know I could replicate this functionality using nAnt tasks or rake scripts, but I want to do it using this mechanism so I'm not repeating myself.
I've investigated this some more, and I've found these links, but none of them solve it cleanly:
VS 2008 version, but no Web.Config transforms
Creates package, but doesn't deploy it..do I need to use MSDeploy on this package?
Deploys package after creating it above...does the UI really do this 2 step tango?
Thanks in advance!
Ok, finally figured this out.
The command line you need is:
msbuild path/to/your/webdirectory/YourWeb.csproj /p:Configuration=Debug;DeployOnBuild=True;PackageAsSingleFile=False
You can change where the project outputs to by adding a property of outdir=c:\wherever\ in the /p: section.
This will create the output at:
path/to/your/webdirectory/obj/Debug/Package/PackageTmp/
You can then copy those files from the above directory using whatever method you'd like.
I've got this all working as a ruby rake task using Albacore. I am trying to get it all done so I can actually put it as a contribution to the project. But if anyone wants the code before that, let me know.
Another wrinkle I found was that it was putting in Tokenized Parameters into the Web.config. If you don't need that feature, make sure you add:
/p:AutoParameterizationWebConfigConnectionStrings=false
I thought I'd post a another solution that I found, I've updated this solution to include a log file.
This is similar to Publish a Web Application from the Command Line, but just cleaned up and added log file. also check out original source http://www.digitallycreated.net/Blog/59/locally-publishing-a-vs2010-asp.net-web-application-using-msbuild
Create an MSBuild_publish_site.bat (name it whatever) in the root of your web application project
set msBuildDir=%WINDIR%\Microsoft.NET\Framework\v4.0.30319
set destPath=C:\Publish\MyWebBasedApp\
:: clear existing publish folder
RD /S /Q "%destPath%"
call %msBuildDir%\msbuild.exe MyWebBasedApp.csproj "/p:Configuration=Debug;PublishDestination=%destPath%;AutoParameterizationWebConfigConnectionStrings=False" /t:PublishToFileSystem /l:FileLogger,Microsoft.Build.Engine;logfile=Manual_MSBuild_Publish_LOG.log
set msBuildDir=
set destPath=
Update your Web Application project file MyWebBasedApp.csproj by adding the following xml under the <Import Project= tag
<Target Name="PublishToFileSystem" DependsOnTargets="PipelinePreDeployCopyAllFilesToOneFolder">
<Error Condition="'$(PublishDestination)'==''" Text="The PublishDestination property must be set to the intended publishing destination." />
<MakeDir Condition="!Exists($(PublishDestination))" Directories="$(PublishDestination)" />
<ItemGroup>
<PublishFiles Include="$(_PackageTempDir)\**\*.*" />
</ItemGroup>
<Copy SourceFiles="#(PublishFiles)" DestinationFiles="#(PublishFiles->'$(PublishDestination)\%(RecursiveDir)%(Filename)%(Extension)')" SkipUnchangedFiles="True" />
</Target>
this works better for me than other solutions.

On VS2012 and above, you can refer to existing publish profiles on your project with msbuild 12.0, this would be equivalent to right-click and publish... selecting a publish profile ("MyProfile" on this example):
msbuild C:\myproject\myproject.csproj "/P:DeployOnBuild=True;PublishProfile=MyProfile"
I've got a solution for Visual Studio 2012: https://stackoverflow.com/a/15387814/2164198
However, it works with no Visual Studio installed at all! (see UPDATE).
I didn't checked yet whether one can get all needed stuff from Visual Studio Express 2012 for Web installation.

This places the published website in the Web..\build\Release folder
I am trying to configure TeamCity 5.0 to run "Publish" target on one of my projects.
When I load the solution in VS 2008 and click publish on the project the website is being build nicely - files on server appearing by themselves etc. Yet when I run the sln file via TeamCity Sln2008 runner the TeamCity returns:
[Project "Portal.csproj" (Publish target(s)):] Skipping unpublishable project.
Has anyone had the same problem?

You could create your own simple build file. For example:
<Project DefaultTargets="Build" ToolsVersion="3.5" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets"/>
<PropertyGroup>
<PackageFolder>C:\Builds\AppServer\Actual</PackageFolder>
</PropertyGroup>
<Target Name="Build" DependsOnTargets="BeforeBuild">
<MSBuild Projects="TeamWork-AppServer.sln"
Targets="Rebuild"
Properties="Configuration=Debug;OutDir=$(PackageFolder)\;"></MSBuild>
</Target>
</Project>
Or you can use VS 2008 Web Deployment Project. Here is a great turtorial.
If it is a WebProject you can use the Microsoft.WebApplication.targets. Unless you have installed the windows SDK on your build agent you will need to copy the targets file into your source control and reference it from your web project by adding:
<Import Project="{path to your tools}\Microsoft.WebApplication.targets" />
You can find the targets file here (depending on your os):
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications
Now you just need to update your msbuild task to reference the right targets:
<MSBuild Projects="{path to your web project file}"
Targets="Build;ResolveReferences;_CopyWebApplication"
Properties="Configuration=Release;Architecture=Any;WebProjectOutputDir={your web root};OutDir={your web root}\bin\" />
Here is how I modified the .csproj file for an ASP.NET MVC project to deploy via TeamCity 5.1.2. In the .csproj file, replace the AfterBuild target with this XML (If there are already commands in your existing AfterBuild, you will have to merge them into these targets):
<PropertyGroup>
<DeployTarget>0</DeployTarget>
<PublishTarget>0</PublishTarget>
<PublishFolder>..\Deployment\YourWebsiteName</PublishFolder>
</PropertyGroup>
<Target Name="PublishProperties">
<CreateProperty Value="$(PublishFolder)">
<Output TaskParameter="Value" PropertyName="WebProjectOutputDir"/>
</CreateProperty>
<CreateProperty Value="$(PublishFolder)\bin\">
<Output TaskParameter="Value" PropertyName="OutDir"/>
</CreateProperty>
</Target>
<Target Name="WebPublish" DependsOnTargets="BeforeBuild;PublishProperties">
<RemoveDir Directories="$(PublishFolder)"
ContinueOnError="true" />
<CallTarget Targets="ResolveReferences;_CopyWebApplication" />
</Target>
<Target Name="Deploy" DependsOnTargets="WebPublish">
<CreateProperty Value="Path\To\Your\Server" Condition="$(DeployFolder) == ''">
<Output TaskParameter="Value" PropertyName="DeployFolder"/>
</CreateProperty>
<RemoveDir Directories="$(DeployFolder)" Condition="$(CleanDeploy) == 1" />
<ItemGroup>
<DeploymentFiles Include="$(PublishFolder)\**\*.*" />
</ItemGroup>
<Copy SourceFiles="#(DeploymentFiles)"
DestinationFolder="$(DeployFolder)\%(RecursiveDir)" />
</Target>
<Target Name="AfterBuild">
<CallTarget Targets="WebPublish" Condition="$(PublishTarget) == 1" />
<CallTarget Targets="Deploy" Condition="$(DeployTarget) == 1" />
</Target>
This script uses the $(PublishTarget) and $(DeployTarget) properties to trigger additional steps after your project is built. The PropertyGroup at the beginning sets the default values to 0, so the extra targets are not run. You can override the default in TeamCity by going to the Properties and Environment Variables page of your build configuration and adding System Properties names "PublishTarget" and "DeployTarget" and setting their value to 1.
The Publish target contains most of the magic. This makes a call to the Visual Studio _CopyWebApplication target to output the website to the PublishFolder. By default the publish folder is "..\Deployment\YourWebsiteName" relative to the project file, but this can also be overridden with a System Property. The Deploy target takes the files output by the Publish target and copies them to the DeployFolder. DeployFolder can be set with a System Property in TeamCity or you can replace the "Path\To\Your\Server" path in the Deploy target.
You could also skip the extra Deploy step by simply setting the PublishFolder to whatever your deployment destination is. This script depends on the "Microsoft.WebApplication.Build.Tasks.Dll" and "Microsoft.WebApplication.targets" files installed by Visual Studio, but you can simply copy the files from your developer workstation to the build server. The default location is "C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications".
I have this same problem, here's what I've tried:
I have a solution file in Visual Studio 2010, committed to a Mercurial repository.
I have setup an FTP server for the root directory of the site to publish to, and publishing from within Visual Studio 2010 locally works nicely, it connects and uploads everything as expected, and the website works.
Now, I wanted to automate this on every push to the central Mercurial repository, and since I'm using TeamCity, I discovered that the field to specify the Target of the build, usually "Rebuild" can also take "Publish", so I specified "Rebuild;Publish", as per the documentation and help.
I have verified that after publishing in Visual Studio, and committing new files, a file named ProjectName.Publish.xml is accompanying my ProjectName.csproj file, and this file is pulled down into the server directory when TeamCity builds.
Yet, no publishing is done, and when I check the build log, it says:
[19:01:02]: [Project "Test.sln" (Rebuild;Publish target(s)):] Project "Test.UI.Web.csproj" (Publish target(s)):
[19:01:02]: [Project "Test.UI.Web.csproj" (Publish target(s)):] Skipping unpublishable project.
Exactly as the question here says.
Note that this is a development site, publishing just so that we can let more people test changes, so don't get into a discussion of whether this is actually a good idea or not.
Note: I do not care in which way the files are published, I just need the single TeamCity build-step to actually do it, so if anyone got a MSBuild-like solution that just sidesteps TeamCity, then I would be satisfied
Have you tried to execute Visual Studio directly, rather than relying on MSBuild to publish the project directly. MSBuild can't execute certain kinds of projects. I had a similar problem with getting MSI's built from within Team City.
I'm taking a guess at the exact commandline settings to this, since I don't know your exact setup.
<PropertyGroup>
<buildconfiguration>Release</buildconfiguration>
<DevEnv>C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.com</DevEnv>
</PropertyGroup>
<Exec Command="%22$(DevEnv)%22 /build $(buildconfiguration) $(teamcity_build_checkoutDir)\Test.sln /project Test.UI.Web.csproj"/>
If you're using the Team City solution runner as your build runner, you'll have to switch to MSBuild.
If you want to stay with the Team City runner, you could always try adding a project to your solution that will be the last one built, (or do it on the project that currently gets built last), and do the spawning trick as a post-build command line on the project.

What I discovered is that "Shared-addins" are not publishable

Assuming you're using Visual Studio 2008, we're unable to execute the web site

You'll need to use to the MSBuild action to compile the application and then
use one of the other actions (FTP, File Copy, etc) in FinalBuilder to perform
the deployment. Visual Studio 2010 has fixed this problem by performing the

Visual Studio. Publish project from command line
For anyone using Web Application Projects in VS2010, I managed to get TeamCity to package the deliverables and then Web Deploy the package after successfully building the solution.
With a little tweaking, this had the same effect as hitting the 'Publish' button in VS.
My solution has a handful of projects, 1 of which is an ASP.NET MVC Web Application project. I build the solution, package the web app project, and msdeploy the package in 3 steps. I haven't figured out a (better|shorter|simpler|more elegant) way to do this.
I don't have VS installed on my TeamCity server, so I needed to grab both C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\Web and C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\Web Applications and put them both in the same spot on the TeamCity server (the second depends on the first). If you're working w/x64 machines, I'd grab them from both Program Files (x86) and Program Files. You also need to have Web Deploy installed on your machine and (I believe) IIS Management Service (i.e., something listening on https://yourservername:8172/MsDeploy.axd)
There are 3 build steps:
Visusal Studio (sln), Target=Rebuild, Configuration=Debug
MSBuild WebProject.csproj, Targets=Package Commandline=/p:PackageLocation=%teamcity.build.checkoutDir%\Debug.zip /p:Configuration=Debug
Commandline, Executable=%teamcity.build.checkoutDir%\Debug.deploy.cmd, Parameters=
/Y "-setParam:'IIS Web Application Name'='Default Web Site/PreCreatedAppInIis'"
In that last step, 'IIS Web Application Name' is an actual parameter name, don't change it. It's value can either be something like 'Default Web Site' or whatever you named your website in IIS and/or it can be an IIS application path below it. If the application doesn't exist, you may run into errors about the app pool not being configured correctly to host the application. Rather than investigate it, I just created an application in the appropriate app pool. In my case, I'm targeting ASP.NET 4.0 x64 where the default app pool is ASP.NET 2.0 x64.
