Version with branch name if not on master

[torsten-github]

Describe your idea

A proeprty which displays the feature branch name. It's empty if on master. A leading dash is needed to use it as postfix.

Expected Behavior

Default Release is mostly: artifact-v1.0.0
Release on feature branch is now: artifact-v1.0.0-7
Better would be: artifact-v1.0.0-7-my-new-featuer

<version>${artifact-id}-${git.commit.id.describe-short}${git.feature.dashed}</version>

Additional context

Please also have a look at this tool, doing the same in the MS world:

Hello,
thanks for opening your issue here.
That sounds like a very specific property and the properties linked in https://gitversion.net/docs/more-info/variables are also very specific to the branch or tagging pattern used. Not everyone uses or follows that pattern. However you still probability can get away by using the replacementProperties:

<replacementProperties>
  <!--
      example:
      apply replacement only to the specific property git.branch and replace '/' with '-'
      see also [issue 138](https://github.com/git-commit-id/maven-git-commit-id-plugin/issues/138)
  -->
  <replacementProperty>
    <property>git.branch</property>
    <propertyOutputSuffix>something</propertyOutputSuffix>
    <token>^([^\/]*)\/([^\/]*)$</token>
    <value>$1-$2</value>
    <regex>true</regex>
    <forceValueEvaluation>false</forceValueEvaluation>
  </replacementProperty>
</replacementProperties>

When looking at the https://gitversion.net/docs/more-info/variables it seems that all variables can be generated from InformationalVersion using regex expressions following a similar pattern.

Thanks for the prompt feedback. That works.

Didn't know about the <replacementPrperty>. With them I managed to build the desired properties:

• git.branch.feat // empty if master
• git.branch.feat.dashed // prefixed with a dash if not empty

By the way:

I realize it's not that easy to build a semantic compatible version (https://semver.org/)
A tagged 1.2.3 with an additional commit would need to increment the patch part like:
1.2.4+1
On a branch: 1.2.4-feature-xyz+1
