Ansible: Using item(with_items) in changed_when statement

I'm using with_items iterator to execute command: brew services stop {{ item }}.

To handle errors I'd like to use changed_when and use item value in it.

command: brew services stop {{ item }}
  register: stop_services
  changed_when:
   - "'Error: Service `{{ item }}` is not started.' not in stop_services.stderr"
  with_items:
   - memcached
   - kafka

If service is not started, I get following error

failed: [127.0.0.1] (item=memcached) => {"changed": false, "cmd": ["brew", "services", "stop", "memcached"], "delta": "0:00:00.464519", "end": "2016-12-29 18:02:37.795973", "failed": true, "item": "memcached", "rc": 1, "start": "2016-12-29 18:02:37.331454", "stderr": "Error: Service memcached is not started.", "stdout": "", "stdout_lines": [], "warnings": []}

But changed_when statement is ignored.

Is it possible to inject item into changed_when statement?

Ansible version: 2.2

You've got a failing task in the first place. The command module will report failure if the return code from the command was other than zero (in your case "rc": 1) and that's why your changed_when condition is not taken into consideration.

Add the following to prevent failing:

failed_when: false
