ansible_pkg_mgr is unknown on Travis CI instance after installing homebrew

[GlaIZier]

Hello there!

Thank you for your work!

This is a duplicate to an issue described here
In short, ansible_pkg_mgr is unknown after applying this role on Travis CI instance.

I'll see what I can do to reproduce it.

In the meantime...

Since you're running on MacOS and this appears to be a bug that relates to package installation (which was only really tested on Linux distros), I think you can bypass the error by just skipping the sdkman_privilege tag. Do you need privilege escalation/root access for testing your playbook on MacOS?

[GlaIZier]

Yes, your workaround has worked. However, I'm still not sure that this is a bug of your role.

My pipeline on Travis is as follows

1. remove homebrew
2. run the role to install homebrew
3. run this role

I ran some tests.
Before the first step ansible_pkg_mgr = homebrew, after it ansible_pkg_mgr = unknown and after the second step it is still ansible_pkg_mgr = unknown.

Seems like the homebrew role doesn't set up the ansible_pkg_mgr fact... Maybe I could do it manually before executing your role?

[elliotweiser]

It looks MacOS support needs some rework. AFAIK, there should be no need to install homebrew packages, so this task can probably just be skipped if `ansible_os_family == "Darwin". We can tackle this next.

Incidentally, I think if you configure your playbook to run the homebrew role and the sdkman role in separate plays, then gather_facts will repopulate the ansible_pkg_mgr fact with the appropriate value. Granted, I still think there's nothing homebrew-related that should be happening here.

Stay tuned for updates.

As a workaround, I set up ansible_pkg_mgr manually in pre_tasks since I also use another role and experience the same issue.
