Generating code for two schemas of the same vendor

Consider two schemas of the same vendor named db1 and db2. In the first schema (db1), we have a table named productline, and in the second schema (db2), we have a table named product. Our goal is to generate the jOOQ artifacts (to run the jOOQ Code Generator) for these two schemas of the same vendor (here, MySQL) and to execute queries against one or another, and even join these two tables.

Basically, as long as we don't specify any input schema, jOOQ generates code for all the schemas it can find. But since we want to instruct jOOQ to work only on the db1 and db2 schemas, we can do it as follows (here, for Maven):

<database>
 <schemata>
   <schema>
    <inputSchema>db1</inputSchema>
   </schema>
   <schema>
    <inputSchema>db2</inputSchema>
   </schema>
 </schemata...
