How does VersionInBranchBaseVersionStrategy handle version extraction ?

[nzeugaa]

I have a case where i need the release branch to have a prefix like release/uat/v1.2.1.

Gitversion is not able to extract the correct verion for the release in this case. I'm expecting 1.2.1 to be extracted. Am I missing something here ? Do I need to override default config to have the behavior I'm expecting ?

As you can see from the documentation, the default pattern is:

version-in-branch-pattern: (?<version>[vV]?\d+(\.\d+)?(\.\d+)?).*

This pattern should indeed capture v1.2.1 from release/uat/v1.2.1. Is the branch correctly identified as a release branch? Do you have logs from the build you can share?

[nzeugaa]

My understanding was that having a release/** branch should be automatically recognised as a release branch... You can see from the logs that I've created release/uat/v1.0.14, however GitVersion is determining 1.1.0-beta.1 as Semver

Git version determines the possible versions based on the defined version strategies and takes the highest version number available. In your example 1.0.14 is less than 1.1.0.

[HHobeck]

In the GitFlow workflow we have defined the hotfix branch and configured it with is-release-branch: true as well. Probably you need to use the hotfix branch instead of release branch. (see Link[1])

In the GitHubFlow workflow this is not necessary because the release branch is set to increment patch. (see Link[2])

Then how Git Version determines 1.1.0 as highest version ? I have no reference to 1.1.0 ... my understanding is that 1.0.14 should have been the highest version number

[HHobeck]

In the GitHubFlow workflow this is not necessary because the release branch is set to increment patch. (see Link[2])

In the GitFlow workflow it is intentionally because the release branch is set to increment minor.

If you want to patch a version you need to:

• not use the release but the hotfix branch or
• change the increment on release branch or
• use the GitHubFlow workflow.
