Hello,

I'm trying to read the $BRANCH_NAME env vars in my playbook, just like the Wiki example, but it's empty.

- hosts: "{{ lookup('env','BRANCH_NAME') }}"
  gather_facts: false

I'll use the branch name to update some files on target host. Is the any special setup in Ansible or Jenkins for this case? I've tried also with "gather_facts: true" but without success.
