Gitversion: [Windows][Appveyor] InvalidSpecificationException: the given reference name '[branch]' is not valid

[shiftkey]

Version: 5.1.3

Really not sure what's going on here, but after trying a few different things I'm stumped:

• three failing PRs with the same content today: https://github.com/octokit/octokit.net/pull/2104 https://github.com/octokit/octokit.net/pull/2107 and https://github.com/octokit/octokit.net/pull/2108
• GitHub Actions on macOS and Linux not reporting problem
• pull request submitted from branch or fork - same result
• different branch names triggering it for seemingly the same content
• meanwhile other pull requests today haven't had issues when going through the exact same process

Calculating semantic version...

[arturcic]

I think the issue is that the branch contains refs in the name (all 3 attempts had that in the name)

[shiftkey]

@arturcic ugh, you might be right. Any idea why libgit2sharp would complain about that?

[arturcic]

I think that's a question for Libgit2Sharp repo

[shiftkey]

I think the issue is that the branch contains refs in the name (all 3 attempts had that in the name)

Confirmed this is the issue (a new PR submitted without containing refs passes). Going to leave this open for a bit to remind myself to try and reproduce it in isolation and see if I can put something on the libgit2sharp tracker.

[asbjornu]

If changing the name of the branch helps, I'd say that's a bug in GitVersion. Best case, we should handle that gracefully, worst case we should yield an understandable error message indicating that the name of the branch could be the perpetrator.

[shiftkey]

@asbjornu I'd like to figure out why it's only failing on Windows too (as someone who has contributed to libgit2sharp before, I'd like to know why this is failing because it seems a bit absurd).

[stale[bot]]

This issue has been automatically marked as stale because it has not had recent activity. After 30 days from now, it will be closed if no further activity occurs. Thank you for your contributions.

[asbjornu]

@shiftkey, have you had any time to look into this? No rush, just thought I'd ask now that @stalebot reminded me.

[shiftkey]

@asbjornu nah, haven't even opened Windows since then

Changing branch name from NoTicket.FixFixUserPrefsForSiteMap to FixFixUserSettingsForSiteMap is a working waorkaround

[asbjornu]

So the NoTicket. prefix is causing problems, @rducom? Perhaps the . in there? Bizarre, whategver it is. The best way to fix this would be to provide a failing test in the LibGit2Sharp repository, I think.

[rducom]

No the "refs" sub string is causing problem

[asbjornu]

Ok, then I misunderstood this:

Changing branch name from NoTicket.FixFixUserPrefsForSiteMap to FixFixUserSettingsForSiteMap is a working waorkaround

[rducom]

There is "refs" in "Prefs" 😄

[asbjornu]

Yikes! Right you are! I didn't even notice the removal of Prefs. That's profoundly bizarre.
