 Ansible always executes roles listed in ``dependencies`` before the role that lists them. Ansible executes this pattern recursively when you use the ``roles`` keyword. For example, if you list role ``foo`` under ``roles:``, role ``foo`` lists role ``bar`` under ``dependencies`` in its meta/main.yml file, and role ``bar`` lists role ``baz`` under ``dependencies`` in its meta/main.yml, Ansible executes ``baz``, then ``bar``, then ``foo``.

-Ansible treats duplicate role dependencies like duplicate roles listed under ``roles:``: Ansible only executes role dependencies once, even if defined multiple times, unless the parameters, tags, or when clause defined on the role are different for each definition. If two roles in a playbook both list a third role as a dependency, Ansible only runs that role dependency once, unless you pass different parameters, tags, when clause, or use ``allow_duplicates: true`` in the role you want to run multiple times. See :ref:`Galaxy role dependencies <galaxy_dependencies>` for more details.
