How to get Git Tag in Azure Pipelines

Question

In Azure Pipelines, I have enabled git tags to trigger pipelines like so:

trigger:
  branches:
    include:
    - \'*\'
  tags:
    include:
    - \'*\'
<         


        

Answer 1

The accepted answer using git tag -l v* didn't work for me as it didn't order the tags correctly, instead giving 1.1, 1.11, 1.12, 1.2, 1.3, etc.

I found it better to do:

$tags = git tag --sort=-creatordate
$tag = $tags[0]

This sorts the tags correctly for both annotated and unannotated tags, and so the first result is the most recent tag.

Answer 2

According the this doc the Tag which started the build can be found in BUILD_SOURCEBRANCH.

If this build was queued by the creation of a tag then this is the name of that tag. For Azure Pipelines, the BUILD_SOURCEBRANCH will be set to the full Git reference name, eg refs/tags/tag_name.
