Hi Federico This is a common issue when creating some custom implementation of a code generator extension and expecting the jOOQ GenerationTool to pick it up from the classpath. It has to be ... on the classpath. So, this is more of a Maven question than a jOOQ related one. For your custom EnumGenerator to end up on the GenerationTool's classpath (or rather, the generator plugin's classpath), you have to add it as a dependency. This is similar to when you want to use the JPADatabase and have it pick up JPA annotated dependencies from the classpath: https://www.jooq.org/doc/latest/manual/code-generation/codegen-jpa
Essentially, just: 1. Create a separate Maven project containing your EnumGenerator 2. Add that project as a dependency to either your "main" project that runs the code generator, or to the Maven plugin configuration for the code generator Note: You cannot place the EnumGenerator in the same project that runs the code generator plugin, because the code generation phase is "generate-sources", which happens before the "compile" phase in Maven. So your EnumGenerator is simply not yet compiled and installed, when you expect the code generator to consume it. Hope this helps, Lukas On Wed, Sep 5, 2018 at 7:49 PM <[email protected]> wrote: > Hi guys, > > I'm very stuck trying to create a custom generator.
