It looks like the branch being examined is a detached Head

[benfoster]

Hey guys,

Trying to get https://github.com/benfoster/Flo building on Travis and push packages to Nuget when tagged. Unfortunately I'm getting the following error:

WARN [10/21/17 17:08:07:38] An error occurred:
It looks like the branch being examined is a detached Head pointing to commit '90769ab'. Without a proper branch name GitVersion cannot determine the build version.

Any ideas?

Here's the source of the message:

GitVersion/src/GitVersionCore/GitVersionFinder.cs

Lines 36 to 48 in 6d90d26

	void EnsureHeadIsNotDetached(GitVersionContext context)
	{
	if (!context.CurrentBranch.IsDetachedHead())
	{
	return;
	}
	var message = string.Format(
	"It looks like the branch being examined is a detached Head pointing to commit '{0}'. " +
	"Without a proper branch name GitVersion cannot determine the build version.",
	context.CurrentCommit.Id.ToString(7));
	throw new WarningException(message);
	}

And here's the IsDetachedHead extension method:

GitVersion/src/GitVersionCore/LibGitExtensions.cs

Lines 65 to 68 in 6d90d26

	public static bool IsDetachedHead(this Branch branch)
	{
	return branch.CanonicalName.Equals("(no branch)", StringComparison.OrdinalIgnoreCase);
	}

So, for some reason, the checked out branch has a canonical name of (no branch). Ideas why that might be?

@asbjornu just used that link that I sent you to create the above 😄

@gep13: Aha, I need to both link to the blob as well as have from and to line numbers. Thanks!
