What is expected?

I'm running the default config and have a tag called "v0.7.4-preview.1". I would expect that the detected semver for this tag would be "0.7.4-preview.1", but the results are instead the above.

Steps to Reproduce

Create a repository with a tag v0.7.4-preview.1 and checkout that tag. Run dotnet gitversion.

Dear @agocke,

First of all I want to say that for me it is not clear:

• how your repository looks like
• what branch you have used to create the tag

If you checkout a tag then gitversion tries to detect the branch and calculates the next version based on this branch. Normally no branch will be detected if two or more branches are part of the tag (in my opinion this behavior should be changed). Please see the following issue:

• [ISSUE]: GitVersion crashes in GitHub Actions when an action is dispatched on a tag #4212

Please notice that only this tags are used (by detecting the pre-release number) when the label of the branch matches the pre-release label of the tag. If you want to detect all pre-release tags with different labels on lets say main you need to change the configuration (by setting the label to null):

workflow: 'GitFlow/v1'
label:
branches:
  main:
    label:

I'm going to close this issue because I think it will be addressed in #4212.

Happy Branching!
