Question

Im currently trying to generate jooq classes from jpa entities instead of using an existing db.

Following this page and using jooq version 3.9.1, my current pom\'s plugi

Answer 1

Your entities are probably located in the same module as where you put the plugin. This means that the jOOQ code generator is called prior to compiling the module, which means that the JPA-annotated entities are not yet compiled when the jOOQ code generator tries to find them.

The solution is to create the following module dependency graph:

                        +-------------------+
                        | Your JPA entities |
                        +-------------------+
                             ^         ^
                  depends on |         | depends on
                             |         |
          +---------------------+   +---------------------+
          | jOOQ codegen plugin |   | Your application    |
          +---------------------+   +---------------------+
                             |         |
                   generates |         | depends on
                             v         v
                     +-------------------------+
                     | jOOQ generated classes  |
                     +-------------------------+

I've registered an issue to improve the documentation in order to clarify this: https://github.com/jOOQ/jOOQ/issues/6011
