Quick Start

1. Add Dependencies

Copy# gradle/libs.versions.toml
[versions]
postgresql = "42.7.8"
testcontainers = "1.21.4"
jooq = "3.19.28"  # Spring Boot 3.5.x BOM version
flyway = "11.7.2"

[libraries]
jooq = { module = "org.jooq:jooq", version.ref = "jooq" }
jooq-codegen = { module = "org.jooq:jooq-codegen", version.ref = "jooq" }
jooq-meta = { module = "org.jooq:jooq-meta", version.ref = "jooq" }

[plugins]
flyway = { id = "org.flywaydb.flyway", version.ref = "flyway" }
jooq = { id = "nu.studer.jooq", version = "9.0" }

2. Apply jOOQ Configuration

Copy// build.gradle
plugins {
    alias(libs.plugins.flyway)
    alias(libs.plugins.jooq)
}

apply from: "${project.rootDir}/gradle/jooq-config.gradle"

dependencies {
    implementation libs.jooq
    jooqGenerator libs.testcontainers.postgres,
            libs.postgres,
            libs.flyway.database.postgresql
}

3. Generate Code

Copy./gradlew generateJooq

Version Compatibility

Java 21 (Gradle 8.x)

Java 25 (Gradle 9.x)
