I'm the maintainer of a maven-plugin (https://github.com/ktoso/maven-git-commit-id-plugin ) that exposes certain repository information as properties into the build. A user of of this plugin reported that the branch name is not available with a single branch pipeline build under jenkins. From the plugin perspective we rely (especially for the branch identifier) on the environment properties that are being exposed by the [Git Plugin|https://github.com/ktoso/maven-git-commit-id-plugin ]. In particular we use the GIT_LOCAL_BRANCH or GIT_BRANCH . Unfortunately with Jenkins LTS 2.73.1 (2017-09-13) those environment variables are not available and thus making it impossible to retrieve the branch name.
Thank you for your time.
During my initial debugging I noticed that a user could this get to work when using a parameterized build which is not really beautiful since the parameter used need to be set to GIT_LOCAL_BRANCH or GIT_BRANCH since its then automatically exposed as environment variable (would consider this a dirty hack)...
