Jooq in multi module Spring Boot application with Gradle

[rrdiber]

Hi Lukas,

Im trying to use Jooq in a multi module Spring Boot Application with Gradle and JDK 11.

The project is splitted into one module per layer (domain, persistence, service, rest-api) and the jooq dependency ('org.springframework.boot:spring-boot-starter-jooq') is in the persistence module.

For code generation I use etiennestuder/gradle-jooq-plugin and it works fine.

When I run the application and try to execute a query i get the Exception: 

java.lang.ClassNotFoundException: org.jooq.TableOptions
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581) ~[na:na]
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) ~[na:na]
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ~[na:na]
...

 If I use Jooq in a single module Spring Boot Gradle application it works fine.

The problem would seem to be with multi-modules. Please do you have a suggestion about what the problem should be?

Thanks.

Hello,

This class has been added in jOOQ 3.13. You're probably using a Spring Boot version that depends on jOOQ 3.12. Please upgrade your jOOQ dependency.

Thanks,

Lukas

Yes, effectively. Spring boot 2.2.x has 3.12.4 jooq version.

Thanks!

For the record, here's a useful article showing how to override the Spring Boot transitive dependency:

I hope this helps
