There may be a better way to do this but I solved the problem by having a
separate task initially that verifies the variable is set and fails the
play if not (via the fail module).
- name: Checking for required variables
fail: msg="Playbook execution failed - 'revision_no' is required!"
when: not revision_no
If you don't want the play to outright fail, you could replace the fail
module with something like debug.
