Question: Rationale for `notify: -nexus-service-stop` in task `Download nexus_package`

[bzakdd]

Hello! I have a question regarding following task:

- name: Download nexus_package
  ansible.builtin.get_url:
    url: "{{ nexus_download_url }}/{{ nexus_package }}"
    dest: "{{ nexus_download_dir }}/{{ nexus_package }}"
    force: false
    validate_certs: "{{ nexus_download_ssl_verify | default(omit) }}"
    owner: root
    group: root
    mode: "0644"
  check_mode: false
  register: download_status
  until: download_status.status_code == 200
  retries: "{{ nexus_download_retries }}"
  delay: "{{ nexus_download_delay }}"
  notify:
    - nexus-service-stop

Why is notify: - nexus-service-stop here? I don't see the need to restart Nexus if only it's package was downloaded. True change happens when unpacking Nexus:

- name: Unpack Nexus download
  ansible.builtin.unarchive:
    src: "{{ nexus_download_dir }}/{{ nexus_package }}"
    dest: "{{ nexus_installation_dir }}"
    creates: "{{ nexus_installation_dir }}/nexus-{{ nexus_version }}"
    copy: false
    mode: "0755"
  notify:
    - nexus-service-stop

So which triggers nexus-service-stop by itself if it changes.

---

Furthermore I encountered case, when this (in my opinion useless notify: - nexus-service-stop) restarts Nexus needlessly:

• I created a Nexus and left it running for a longer time
  • I didn't set nexus_download_dir so tarball got saved to /tmp
• After a while tarball got wiped from /tmp.
• I run playbook again to apply some minor changes in repositories and unexpectedly it restarts Nexus (since Download nexus_package task state is "changed")

---

If notify: - nexus-service-stop has no purpose in task - name: Download nexus_package task, then I'd consider removing it.

If you agree, I can create a PR.
