在TFS内部获取git分支名称

Question

I have a CI build definition (TFS 2013) triggered by commits to several branches (it is a git repository). I would like to use the branch name inside build process to copy results to the right place. How can I do this?

Answer 1

Make your own CodeActivity Like this...

you need the IBuildDetail BuildDetail as InArgument.

string branch = null;
string commit;

var environmentVariable = BuildDetail.Get(context);
if (environmentVariable != null && !BuildSourceVersion.TryParseGit(environmentVariable.SourceGetVersion, out branch, out commit))
{
    var defaultSourceProvider = environmentVariable.BuildDefinition.GetDefaultSourceProvider();
    if (BuildSourceProviders.IsGit(defaultSourceProvider.Name))
    {
        branch = BuildSourceProviders.GetProperty(defaultSourceProvider.Fields, BuildSourceProviders.GitProperties.DefaultBranch);
    }
}

if (string.IsNullOrEmpty(branch))
{
    throw new Exception("Could not find Branch");
}

Branch.Set(context, branch.Substring(branch.LastIndexOf("/", StringComparison.InvariantCultureIgnoreCase) + 1));

Answer 2

There is whole .git folder accessible during the build, so I can look into the file .git/HEAD using PowerShell. There may be only commit hash (detached HEAD regime), and then some more git calls are required to find out where I really am. All in all, the other answer is probably cleaner.
