I believe this is because variables set via vars_prompt are always defined.
A workaround might be to set a default for revision_no and check it doesn’t
match in your role, e.g.:
vars_prompt:
- name: “revision_no"
prompt: "Input revision number”
default: “invalid”
private: no
…..
roles:
- { role: web, when: revision_no != “invalid” }
I’ve not made extensive use of roles so it seems odd to me that a role would
still execute when a failure is thrown but it must have something to do with
Ansible’s order of execution.
