I am using spring boot 3:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.2</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
And I want to generate a native image using buildpacks but I have an error related to hibernate and hibernate-enhance-maven-plugin. From what I understand, this plugin should generate code at buildtime but it doesn't seem to be working. My pom is:
<build>
<plugins>
<plugin>
<groupId>org.hibernate.orm.tooling</groupId>
<artifactId>hibernate-enhance-maven-plugin</artifactId>
<version>${hibernate.version}</version>
<executions>
<execution>
<configuration>
<failOnError>true</failOnError>
<enableLazyInitialization>true</enableLazyInitialization>
<enableDirtyTracking>true</enableDirtyTracking>
<enableAssociationManagement>true</enableAssociationManagement>
<enableExtendedEnhancement>false</enableExtendedEnhancement>
</configuration>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<image>
<env>
<BP_JVM_VERSION>17</BP_JVM_VERSION>
</env>
</image>
</configuration>
</plugin>
</plugin>
</build>
when I run mvn -Pnative spring-boot:build-image
I can see in the console:
[INFO] --- hibernate-enhance-maven-plugin:6.1.5.Final:enhance (default) @ medea-core ---
[INFO] Starting Hibernate enhancement for classes on /home/tronxi/workspace/medea/medea-core/target/classes
Feb 15, 2023 11:54:10 PM org.hibernate.Version logVersion
INFO: HHH000412: Hibernate ORM core version 6.1.5.Final
so it looks like the plugin is running, however when I make a request involving a lazy entity I get this error

In case it can help this is my complete pom:
