3.6.2: TFS15RC1: An unexpected error occurred: System.InvalidOperationException: Could not find a 'develop' or 'master' branch, neither locally nor remotely.

Server: TFS15RC1
Agent version: 2.103.1
GitVersion version: 3.6.2

On TFS15RC1 it seems Microsoft changed the way in which Git retrieves it's data, which causes at least pull request builds to fail when calling the GitVersion task, if the repository has not fetched the master and/or dev branch before.

Repro:

• Create a build definition and add at least the GitVersion task. I had a release branch as default in the build definition (releases/3.0), but I don't think this matters.
• Select this build definition in the branch policy in 'Automatically build pull requests'.
• Create a pull request and the GitVersion build task fails. (See log output below).

Optional:

• If you want the repro to keep working (even after manually fetching the dev and/or master branch) add the Build.Clean=source variable to the build definition.

If I log in to the build agent's source directory and manually fetch the dev and/or master branch (or all with git fetch -all), the build will work.

Here's the error on GitVersion v4.0.0-beta.2

Does the workaround provided in #993 solves your issue?

[asbjornu]

This just occurred to me on Travis, so I don't think the problem is build server related.

[nphmuller]

Workaround works fine. Thought about using, but wasn't sure how to pass the access token.
Thanks for helping out!

[JakeGinnivan]

@asbjornu why is it cloning your fork:

git clone --depth=50 --branch=feature/mkdocs-build https://github.com/asbjornu/GitVersion.git asbjornu/GitVersion

Could that be the issue?

[JakeGinnivan]

Going to close this one down, Will use the other issue to track, I will likely move this knowledge into GitVersion itself so it will throw if the OAuth token is not passed for PR's

[asbjornu]

@JakeGinnivan It's cloning my fork since this is my personal Travis project. I like to have Travis run the tests before I PR it against the GitTools repository. 😄
