About version_from_last_tag

Perform a regex on last (latest) git tag and perform a regex to extract a version number such as Release 1.2.3

This action requires that a repo have a remote set - as part of the process is to fetch the latest tag set. It was initially designed for cases where a repo was shallow cloned, however it works perfectly well with full repos as well. The command will try to fetch the last branch tag entry and try to parse it using a regex. The default regex format is

^\\D*([\\.0-9]*)

It will look for a sequence of non-digets and then at the first digit it will capture any of the following characters: 0 1 2 3 4 5 6 7 8 9 .

So for example

  release-1.2   => 1.2
  v1.0          => 1.0
  version1      => 1
  version 1.2.3 => 1.2.3

This plugin was designed to be used with a GitFlow workflow so that version numbers for the release branch would always match the latest tag on master

Usage

To force the current version number to match whatever the latest release version is you would use the following code block

    #Extract Version Number and set it
    version_number = version_from_last_tag
    increment_version_number(version_number: version_number)
    increment_build_number
