jOOQ does not generate sources

问题

I am trying to include jOOQ into my code, however no code is being generated.

When executing mvn clean generate-sources, no sources are generated. I want it to create a Category class, which is defined in the following schema.sql-file.

CREATE TABLE IF NOT EXISTS category (
  id INTEGER IDENTITY PRIMARY KEY,
  name VARCHAR(100),
  description VARCHAR(2000),
  age_group VARCHAR(20),
  created DATETIME,
  inserted BIGINT
);

My pom.xml file looks like this:

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

I would assume that a directory gensrc should be created with the appropriate class inside. The maven build runs successfully without any errors.

You can find the whole project in this GitHub repository.

回答1:

You're using an in-memory database: jdbc:hsqldb:mem:testdb. When the jOOQ code generator starts, it receives a new database that is empty, not the database that you may have created elsewhere.
