java - JOOQ Doesn't Generate

Question

I was following here. I used postgresql instead of h2. I was able to build the project with some additional fields.

I created a package database under com.example.demo, but it was still empty after project was built.

build.gradle:

buildscript {
    ext {
        springBootVersion = '2.4.2'
    }
    repositories {
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath 'org.jooq:jooq-codegen:3.14.4'
        classpath 'org.postgresql:postgresql:42.2.18'
    }
}


apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '15'

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-jdbc'
    implementation 'org.springframework.boot:spring-boot-starter-jooq'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.flywaydb:flyway-core'
    runtimeOnly 'org.postgresql:postgresql'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

import org.jooq.codegen.GenerationTool
import org.jooq.meta.jaxb.*

task generate {
    def configuration = new Configuration()
    configuration
            .withJdbc(new Jdbc()
                    .withDriver('org.postgresql.Driver')
                    .withUrl('jdbc:postgresql://localhost:5432/vertx')
                    .withUser('postgres')
                    .withPassword('postgres'))
            .withGenerator(new Generator()
                    .withDatabase(new Database().withInputSchema('public'))
                    .withGenerate(new Generate()
                            .withPojos(true)
                            .withDaos(true))
                    .withTarget(new Target()
                            .withPackageName('com.example.demo.database')
                            .withDirectory('src/main/java')))

    doLast {
        GenerationTool.generate(configuration)
    }
}

Is there something I am missing? Why can I not see pojos and daos in database package? My database has only one table with 2 columns.

BUILD SUCCESSFULL when I type ./gradlew generate, but nothing gets generated.

Your file looks okay. I had a similar issue (while using maven). Try three things (that worked for me):

1. check case of the schema in "withInputSchema" property. Try to pass uppercase PUBLIC.
2. try to change 'src/main/java' to './src/main/java'
3. add "includes" and pass .* in it (to generate for all tables in the schema)
