Note that __java_packages is a 'magic variable' (a coin I'm using here, not an official term). The way the role uses the variable is:

  • If you set java_packages, it will use that.
  • If you don't set java_packages, it will fall back to __java_packages, which is platform/version specific.

The reason is Ansible doesn't have an easy way to define default variables that vary by OS or platform... so I use this 'magic' naming convention and have a set_fact task in the role that sets it if not set by you.

Your inventory / playbook / extra vars should always take precedence, if you set java_packages.
