Question

This is my first dive into MSBuild so I’m feeling pretty lost.

The end goal is to run an executable which will output a file, and we want the output of the build to be that file. In this build there is no VS project what so ever.

The build is being run by TFS build services.

At this point all I’m trying to do is generate a file and have it copied to the drop folder.

Here is the contents of my .proj file

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

 <Target Name="Build">
  <Message Text="Output Dir: $(OutDir)" />
  <MakeDir Directories="$(OutDir)" />
  <Exec Command='dir /s > \\ANetworkPath\dir.txt
    dir /s > $(OutDir)Dir2.txt'/>
 </Target>
</Project>

The first command of writing dir to the network path succeeds, however it doesn’t show the existence of $(OutDir). So I thought I would try to create it with MakeDir. When the second dir command executes it errors because the path doesn’t exist.

TFS is running MSBuild with the following command

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe /nologo /noconsolelogger "C:\Builds\1\Scratch\Test Build\Sources\user\Test\Build.proj" /m:1 /fl /p:SkipInvalidConfigurations=true  /p:OutDir="C:\Builds\1\Scratch\Test Build\Binaries\\" /p:VCBuildOverride="C:\Builds\1\Scratch\Test Build\Sources\user\Test\Build.proj.vsprops"  /dl:WorkflowCentralLogger,"C:\Program Files\Microsoft Team Foundation Server 2010\Tools\Microsoft.TeamFoundation.Build.Server.Logger.dll";"Verbosity=Normal;BuildUri=vstfs:///Build/Build/111;InformationNodeId=6570;TargetsNotLogged=GetNativeManifest,GetCopyToOutputDirectoryItems,GetTargetPath;TFSUrl=http://tfshost:8080/tfs/Test%20Collection;"*WorkflowForwardingLogger,"C:\Program Files\Microsoft Team Foundation Server 2010\Tools\Microsoft.TeamFoundation.Build.Server.Logger.dll";"Verbosity=Normal;"

The only output is in the file written on the network:

Here is the build log:

Am I going about this completely wrong?

Answer 1

Your code works fine in my computer.
However : you should instantiate OutDir property either by passing it in Command-Line invokation :

c:\WINDOWS\Microsoft.NET\Framework\v4.0\MSBuild.exe test.proj /p:OutDir=MyNewDir

or with a PropertyGroup element :

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <PropertyGroup>
    <OutDir>MyNewDir</OutDir>
  </PropertyGroup>

 <Target Name="Build">
  <Message Text="Output Dir: $(OutDir)" />
  <MakeDir Directories="$(OutDir)" />
  <Exec Command='dir /s > \\ANetworkPath\dir.txt
    dir /s > "$(OutDir)\Dir2.txt"'/>
 </Target>
</Project>

Notice the \ added in the dir command.

EDIT : I get it : you have a space in your output path. The command dir /s > my path\Dir2.txt is not gonna work unless you encapsulate the path with quotes. Try the following commands in the dos shell :

mkdir C:\Builds\1\Scratch\Test Build\Binaries\
mkdir "C:\Builds\1\Scratch\Test Build\Binaries\"

You will notice the difference (the first line creates two directories one C:\Builds\1\Scratch\Test and one .\Build\Binaries). I edited my code above to add quotes.
