Not able to read Git Environment variables Jenkins using Groovy Jenkinsfile

git jenkins groovy jenkins-pipeline jenkinsfile

This won't work due to lack of double quotes, missing curly braces, and missing env.:

sh 'echo $BRANCH_NAME'

This works as expected in a Jenkinsfile:

node {    sh "echo ${env.BRANCH_NAME}"}

git jenkins groovy jenkins-pipeline jenkinsfile

So, anyone else who has stumbled onto this Stackoverflow issue should be aware that this is a bug with the current pipeline situation.

Essentially the plugin is not able to correctly add environment variables due to some incompatibilities with pipeline.

git jenkins groovy jenkins-pipeline jenkinsfile

This is fixed in Git plugin 3.3.1
