BUG: Could not find a 'develop' or 'master' branch, neither locally nor remotely

[MrHinsh]

Guys,

I have a very strange problem... System.InvalidOperationException: Could not find a 'develop' or 'master' branch, neither locally nor remotely is the message I get when trying to build a pull request. From either MASTER or a topic branch this all works perfectly.

Why might this be happening?

I have attached the full log and you can see it finds tags and lists the graph...

mode: ContinuousDeployment
continuous-delivery-fallback-tag: ''
branches:
  master:
    mode: ContinuousDeployment
    tag: ''

@MrHinsh: This looks like a duplicate of #912. Can you please peek at it and see if there's anything in there that can help? Also, if this is a duplicate, please close and continue the discussion in #912. 😄

[pascalberger]

@MrHinsh See #993 for a workaround by adding an additional git fetch task to the build pipeline

[MrHinsh]

Looks like this is the same issue as #993 and I am closing it here. You can also find more info at #912

I found in bitbucket that when it does a clone passing branch as command line arg, git clone result does not create neither master or develop branch and thus GitVersion is unable to find local branch.
In that case, I tweaked GitVersion file to accept remote branch as valid develop/master branch.
This code is my config:

mode: ContinuousDeployment
branches:
    master:
        regex: (^master$|^origin\/master$)
    develop:
        regex: (^dev(elop)?(ment)?$|^origin\/dev(elop)?(ment)?$)

This solved the issue in question.

This solved the issue in question.

thanks for this! i would've never checked default configuration because of the error message below

System.InvalidOperationException: Could not find a 'develop' or 'master' branch, neither locally nor remotely.

in my case the jenkins git-plugin did fetch all remote refs, it just did not create local branches tracking remote ones. I figured this should've been sufficient, given the above error message.. after the update to the regex outlined above, it is. Maybe this should be the actual default configuration unless i'm missing something ( and i may be .. )

[asbjornu]

Maybe this should be the actual default configuration

Yep, indeed it seems like it should. A PR changing the default regex and adding a new test for origin/master would be warmly welcomed. 🙏

[andlaz]

On second thought.. can you think of no use case where someone would depend on these regex values being what they are, by default? Additionally, what of remotes not named origin ? What if the regular expression ( (^master$|^origin\/master$) as above or even (^master$|^.*\/master$) ) returns multiple refs?

Maybe this is as simple as the exception message not assuming any kind of particular configuration and just guiding the user towards the config keys that were used to draw this conclusion, e.g. Could not find a 'develop' or 'master' branch, verify develop.regex and master.regex configuration values ?

[asbjornu]

Those are good points, @andlaz. But I think we can base GitVersion's assumptions on Git's defaults, which is to name the default branch master or main and the clone remote origin. Hard coding those defaults in GitVersion is therefore fine, imho. It should also be unnecessary to have a local tracking branch, since the branch references provided by origin are exactly the same, only placed differently.

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.

I've come across this problem recently, and the regex solution works fine. I wonder if the GitVersion init command couldn't retrieve the repo's main branch and apply it to a regex entry in the GitVersion.yml file?
