Using SpringBoot 3 and Hibernate 6 any generated Liquibase changelogs based on my Java Entity classes are empty

Question

I have a SpringBoot 3 based Gradle project that uses Hibernate 6 and Liquibase.

The goal is to use the liquibase-hibernate6 dependency to generate an initial Liquibase changelog containing the details of my Java Entity class i.e Item.java.

The problem is that the generated changelog is basically empty.

What is missing in order to generate Liquibase changelog from my Java Entity class?

val liquibaseVersion: String = "4.23.0"
val liquibaseGradlePluginVersion: String = "2.2.0"

plugins {
    java
    war

    id("org.springframework.boot") version "3.1.1"
    id("io.spring.dependency-management") version "1.1.0"
    id("org.liquibase.gradle") version "2.2.0"
}

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

java {
    sourceCompatibility = JavaVersion.VERSION_17
}

repositories {
    mavenCentral()
}

dependencies {

    implementation("org.postgresql:postgresql:42.6.0")
    implementation("info.picocli:picocli:4.6.3")

    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-web")

    implementation("org.liquibase:liquibase-core:$liquibaseVersion")
    implementation("org.liquibase:liquibase-gradle-plugin:$liquibaseGradlePluginVersion")
    implementation("org.hibernate.orm:hibernate-core:6.2.5.Final")
    implementation("org.liquibase.ext:liquibase-hibernate6:$liquibaseVersion")

    implementation("com.fasterxml.jackson.core:jackson-core")
    implementation("com.fasterxml.jackson.core:jackson-databind")
    implementation("com.fasterxml.jackson.dataformat:jackson-dataformat-yaml")

    providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")

    liquibaseRuntime("org.postgresql:postgresql:42.6.0")
    liquibaseRuntime("info.picocli:picocli:4.6.3")
    liquibaseRuntime("org.liquibase:liquibase-core:$liquibaseVersion")
    liquibaseRuntime("org.liquibase.ext:liquibase-hibernate6:$liquibaseVersion")
    liquibaseRuntime("org.hibernate.orm:hibernate-core:6.2.5.Final")
    liquibaseRuntime("org.springframework.boot:spring-boot-starter-data-jpa")
    liquibaseRuntime(sourceSets.getByName("main").output)
}

tasks.withType<Test> {
    useJUnitPlatform()
}

liquibase {
    activities.register("main") {
        this.arguments = mapOf(
            "changelogFile" to "src/main/resources/config/liquibase/changelog/0.1.0/000000_00000000_initial-changelog.xml",
            "url" to "hibernate:spring:com.example?dialect=org.hibernate.dialect.PostgreSQLDialect"
        )
    }
}

I have a Java Entity:

package com.example.demo;

import jakarta.persistence.*;

@Entity
public class Item {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id", nullable = false)
    private Long id;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
}

Contents of Liquibase changelog after running generateChangeLog via Gradle:

<?xml version="1.1" encoding="UTF-8" standalone="no"?>
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog" xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-latest.xsd"/>

Using SpringBoot 3 and Hibernate 6 any generated Liquibase changelogs based on my Java Entity classes are empty
