fwiw, check out the libinput .gitlab-ci.yml for how to use the project name
here instead of the number. Either will work though. You can also use 
  image: registry.freedesktop.org/libinput/libinput/jq:latest
that way you can skip the before_script stage and speed up everything
significantly

I'd prefer the more explicit:
    only:
      refs:
      - master

but afaict yours will work just fine. However, 
you probably want this here:

   only:
       variables:
          - $CI_PROJECT_PATH == "wayland/wayland"

otherwise your're trying to run the job on any push to wayland master in any
personal project. They won't have the token set and thus not do anything but
waste time.

also add a single line
  dependencies:

to indicate you don't care about any dependencies from previous steps

Cheers,
