Cannot eqwalize a single file/module: rebar3 command build_info not found

I'm trying to run some comparisons between Gradualizer / Etylizer / Eqwalizer, but with the last one I'm getting the following error:

Rebar3 3.22.0 is the latest release and https://rebar3.org/docs/commands/ doesn't mention a build_info command, so I'm not sure what's going on. Is there something I could try to run eqwalizer on a single file?

Have you followed the steps in https://github.com/WhatsApp/eqwalizer#using-it-with-rebar3-projects?

Pay attention to the step 3 about adding dependencies (a library and a plugin). The build_info command is provided by the plugin.

Ahhh, right, that's it! Thanks for the pointer and sorry for the confusion.
