Jooq is unable to find driver for postgres database

I have a spring-boot app that uses gradle, postgres and jooq. I want Jooq's code generator to create the classes for me but during gradle clean build I get an error regarding to the driver

java.lang.ClassNotFoundException: org.postgresql.Driver

I don't understand why the driver is not found. This are some of the relevant aspects of my gradle.build file:

plugins {
    id "org.springframework.boot" version "2.0.2.RELEASE"
    id 'nu.studer.jooq' version '3.0.1'
}

I an using version 2.0.2.RELEASE of spring boot. This are my dependencies:

dependencies {
    implementation "org.springframework.boot:spring-boot-starter-web:$SPRING_VERSION"
    implementation "org.springframework.boot:spring-boot-starter-actuator:$SPRING_VERSION"
    implementation "org.springframework.boot:spring-boot-starter-jooq:$SPRING_VERSION"
    implementation "org.springframework.boot:spring-boot-starter-data-jpa:$SPRING_VERSION"
    implementation "org.springframework.boot:spring-boot-starter-jooq:$SPRING_VERSION"
 implementation 'org.postgresql:postgresql:42.2.5'

}

This is the Jooq config i have in my gradle file

jooq {
   myApp(sourceSets.main) {
       jdbc {
           driver = 'org.postgresql.Driver'
           url = "jdbc:postgresql://${db_host}:${db_port}/${db_name}"
           user = "${db_username}"
           password = "${db_password}"
           schema = 'public'
       }
       generator {
           name = 'org.jooq.util.DefaultGenerator'
           strategy {
               name = 'org.jooq.util.DefaultGeneratorStrategy'
           }
           database {
               name = 'org.jooq.util.postgres.PostgresDatabase'
               inputSchema = 'public'
           }
           generate {
               relations = true
               deprecated = false
               records = true
               immutablePojos = false
               fluentSetters = true
           }
           target {
               packageName = 'com.mycompany.mayapp.model.jooq'
               directory = 'out/production/classes/generated'
           }
       }
   }
}```

The gradle-jooq-plugin needs dependencies in a separate configuration. It uses the jooqRuntime configuration to detect the needed dependencies, it doesn't use the compile or implementation configuration.

Adding the following to your dependencies should do the trick

jooqRuntime 'org.postgresql:postgresql:42.2.5'

This way the plugin picks up the driver and will generate the model classes.
