Request for help: Using versioning with Gitlab pipelines

[dl6lr]

Hi,

thank you for the great plugin.
I am evaluating the versioning plugin and managed to find a way to produce version infos the way we use it. This is working fine with local builds where git is available for information retrieval, but lacks on Gitlab runners.

Local working:
default branch master -> master-SNAPSHOT
branch release/1.0 -> 1.0.0-SNAPSHOT
tag 1.0.0 -> 1.0.0
branch release/1.0 -> 1.0.1-SNAPSHOT

on Gitlab I get HEAD-SNAPSHOT by default. By setting up an environment in .gitlab-ci.yml like
export GIT_BRANCH=$CI_COMMIT_REF_NAME;
and using the environment variable GIT_BRANCH in

versioning { 
  branchEnv = ['GIT_BRANCH']
  ...
}

I get: master-SNAPSHOT and 1.0.0-SNAPSHOT as expected.

Tags however are not avaliable through environment variables or do I miss something? I can provide the TAG from the CI variable $CI_GIT_TAG, but to what environment variable? Any help is appreciated.
