Spring : NoClassDefFoundError

Question

I was trying to rearrange my pom.xml to resolve some problem in my application and a new error appeared when in run a Maven Install :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/bloombooking/spring/PersistenceJPAConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/tool/schema/spi/DelayedDropRegistry

I don't know how i've messed up with it to create that and i can't find help anywhere... Here is my pom.xml :

<?xml version="1.0" encoding="UTF-8"?>

Can someone give me some help ? Thanks

Answer 1

You don't have to specify dependencies for spring-context,spring-orm and hibernate-entitymanager in you pom.xml as you are using Spring Boot starter web and jpa dependencies which will pull the required jar files. Please cleanup your pom file. Class DelayedDropRegistry for which you are getting NoClassDefFoundError is available in hibernate-core jar file since 5.1 release. Check your local maven repository for the hibernate-core jar files and versions. You can use maven > update project to update dependencies and clean build your project. Hope this helps.
