I have upgrade to spring boot 3.4.2, now I getting below error while application start up.

* * *

APPLICATION FAILED TO START

* * *

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

```
org.springframework.orm.hibernate5.LocalSessionFactoryBuilder.scanPackages(LocalSessionFactoryBuilder.java:365)

```

The following method did not exist:

```
'void org.springframework.orm.hibernate5.LocalSessionFactoryBuilder.addAttributeConverter(java.lang.Class)'

```

The calling method’s class, org.springframework.orm.hibernate5.LocalSessionFactoryBuilder, was loaded from the following location:

```
jar:file:/C:/Users/xxxxx/.m2/repository/org/springframework/spring-orm/6.2.2/spring-orm-6.2.2.jar!/org/springframework/orm/hibernate5/LocalSessionFactoryBuilder.class

```

The called method’s class, org.springframework.orm.hibernate5.LocalSessionFactoryBuilder, is available from the following locations:

```
jar:file:/C:/Users/xxxxx/.m2/repository/org/springframework/spring-orm/6.2.2/spring-orm-6.2.2.jar!/org/springframework/orm/hibernate5/LocalSessionFactoryBuilder.class

```

The called method’s class hierarchy was loaded from the following locations:

```
org.springframework.orm.hibernate5.LocalSessionFactoryBuilder: file:/C:/Users/xxxx/.m2/repository/org/springframework/spring-orm/6.2.2/spring-orm-6.2.2.jar
org.hibernate.cfg.Configuration: file:/C:/Users/xxxx/.m2/repository/org/hibernate/orm/hibernate-core/6.6.5.Final/hibernate-core-6.6.5.Final.jar

```

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.orm.hibernate5.LocalSessionFactoryBuilder

No idea what you did there, but it seems you messed up your application dependencies. Either way, this is a Hibernate ORM forum, not a Spring forum, so please ask that questions in Spring forums.
