Error creating Bean entityManager, because of unknown type "record"

Question

There must be some dependency issue, but I could not figured out where and how to solve it.

I'd like to implement State Aggreages (Axon) in my Spring Application (with Kotlin) and save them on a h2 embedded database for presentation purposes.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unknown access type record

My gradle:

plugins {
    id("org.springframework.boot") version "3.2.2"
    id("io.spring.dependency-management") version "1.1.4"
    kotlin("jvm") version "1.9.22"
    kotlin("plugin.spring") version "1.9.22"
}

group = "org.example"
version = "0.0.1-SNAPSHOT"

java {
    sourceCompatibility = JavaVersion.VERSION_21
}

repositories {
    mavenCentral()
    maven(url = "https://jitpack.io")
}

dependencies {
    // Spring Dependencies
    implementation("org.springframework.boot:spring-boot-starter-web:3.2.2")
    implementation("org.springframework.data:spring-data-jpa:3.2.2")

    implementation("org.axonframework:axon-spring:4.9.2")

    // Others

    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.8.0-RC2")
    implementation("io.spring.gradle:dependency-management-plugin:0.5.1.RELEASE")
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs += "-Xjsr305=strict"
        jvmTarget = "21"
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Due to documentation and other stack-overflow threads, the implementation should be correct.

Answer 1

You have to remove next ones dependencies frombuild.gradle file, I guess that the problem is in: versions compatibility.

// DB Depdendencies
implementation("jakarta.persistence:jakarta.persistence-api:3.2.0-M1")
implementation("org.hibernate:hibernate-core:6.4.4.Final")
implementation("org.hibernate:hibernate-entitymanager:6.0.0.Alpha7")

Because you are using io.spring.dependency-management and spring will automatically inject necessary dependencies for you and also version compatibility.
