# The template generates jobs for gems vendored in the main GitLab project
# under `gem_path_prefix` (defaults to `gems/`).
#
# Inputs
# - `gem_name`: The name of the gem, i.e. if the gem is located at `gems/gitlab-rspec`, `gem_name` should be set to `gitlab-rspec`.
# - `gem_path_prefix`: The prefix of the gem path, i.e. if the gem is located at `vendor/gems/gitlab-rspec`, `gem_path_prefix` should be set to `vendor/gems/`. Defaults to `gems/`.
