The manual's tutorial on https://www.jooq.org/doc/latest/manual/getting-started/tutorials/jooq-in-7-steps/ has been contributed a very long time ago by Ikai Lan, see also: https://ikaisays.com/2011/11/01/getting-started-with-jooq-a-tutorial/

It is a frequent source of frustration for new users, because it's notoriously outdated, see e.g. #9723

It uses a standalone code generation approach, which is not at all what I'd recommend new users do. It would be much better if new users could download an integration tested, maven-based example project from github that uses an in-memory database, such as H2, to minimise dependencies and risks of doing something wrong. Even the MCVE would be better suited than the current tutorial.
