Get build agent folder path in tfs build - batch-file

Question

How to access TFS build agent folder path in using batchfile?
I am calling runscript tool from build workflow (calling windows batchfile).
I tried to use the environment variable BUILD_REPOSITORY_LOCALPATH ($(BUILD_REPOSITORY_LOCALPATH), $env:BUILD_REPOSITORY_LOCALPATH) but they dint give any result.
Need some assistance on this.

Answer 1

I used another workaround for this instead of getting by workspace. From sourceDirectory folder i drill down to find my solution project file, the path containing my solution project is the local directory path i need
From batchfile i call my exe and pass %TF_BUILD_SOURCESDIRECTORY% as parameter.
string[] subdirectoryEntries = Directory.GetDirectories(targetDirectory)
// targetdirectory would be the input parameter from batch file`
for (int i = 0; i < subdirectoryEntries.Length ; i++)
{
// My root folder always contains a specific folder with name MyFolder
// and a file Myfile.sln
if (subdirectoryEntries[i].ToString().ToLower().Contains(#"MyFolder"))
{
Console.Writeline("My source code path is " + targetDirectory);
}
//Similarly I check for Myfile.sln and then get my path.
}
This may be a very crude way, this worked for me.

The variable you are looking for is TF_BUILD_SOURCESDIRECTORY. Please refer to the XAML build documentation.

Answer 3

TF_BUILD_SOURCESDIRECTORY: The sources sub-directory of the build agent working directory. This directory contains your source code. For example: C:\Build\BuildBot3\CoolApp\CIBuild\src.
If you want to get C:\TFS_Build\src\V9, it's just local path: the path that you have mapped the server path to on your machine. There is not any built-in TF_BUILD environment variables could achieve your requirement.
You could use TFS API to get the related info, first get the workspace information for the build server's workspace, then do the get option, a sample code for your reference:
// Get the workspace information for the build server's workspace
var workspaceInfo = Workstation.Current.GetLocalWorkspaceInfo(sourcesDirectory);
// Get the TFS Team Project Collection information from the workspace cache
// information then load the TFS workspace itself.
var server = new TfsTeamProjectCollection(workspaceInfo.serverUri);
var workspace = workspaceInfo.GetWorkspace(server);
Once you have a workspace, you can query it for the path mappings. It
will do the necessary translation from server to local path based on
your workspace mappings. For example:
workspace.GetServerItemForLocalItem("C:\TFS_Build\src\V9");
and
workspace.GetLocalItemForServerItem("$/DEV/V9");
This mechanism will only work, however, if your build definition
actually sets up the workspace to include these files.
