How to get jOOQ code generator to tell me what's wrong?

I'm trying to get the jOOQ code generator to do its thing based on my Flyway scripts. Here's my configuration:

        GenerationTool.generate(Configuration()
            .withLogging(Logging.TRACE)
            .withOnError(OnError.FAIL)
            .withGenerator(Generator()
                .withDatabase(Database()
                    .withName("org.jooq.meta.extensions.ddl.DDLDatabase")
                    .withIncludes(".*")
                    .withProperties(
                        Property().withKey("scripts").withValue("src/main/resources/db/migration/*.sql"),
                        Property().withKey("sort").withValue("flyway"),
                        Property().withKey("defaultNameCase").withValue("lower")))
                .withGenerate(Generate()
                    .withTables(true)
                    .withPojos(true)
                    .withDaos(true)
                    .withGeneratedAnnotation(true)
                    .withJavaTimeTypes(true)
                    .withRecords(true))
                .withTarget(Target()
                    .withClean(true)
                    .withPackageName("my.package.name")
                    .withDirectory("src/main/java"))

(Ignore the missing news, it's Kotlin)

Currently it doesn't seem to be doing anything, including not logging anything. I know the code is executed, but nothing is generated. How do I make it actually log something, so that I have something to go on?
