Question

I am trying to implement hibernate metamodel in my spring boot application. I am getting

Annotation processor 'org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor' not found

above error, while building applications.

My Gradle configuration and detailed error given below

While running the application with ./gradlew build --info i am getting below error

Im using spring-boot 2.2.6, Is there any version compatibility available for hibernate-jpamodelgen.

Answer 2

You don't need to use any plugin to generate JPA metamodel. It is enough to use the line

annotationProcessor 'org.hibernate.orm:hibernate-jpamodelgen:<6.1.1.Final now or other version>'

in build.gradle dependencies block.
