Error starting spring boot "An attempt was made to call a method that does not exist"

Question

When i run the spring boot app, intellij returns me an error:

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

org.hibernate.envers.boot.internal.TypeContributorImpl.contribute(TypeContributorImpl.java:30)

The following method did not exist:

org.hibernate.boot.model.TypeContributions.contributeJavaTypeDescriptor(Lorg/hibernate/type/descriptor/java/spi/JavaTypeDescriptor;)V

The method's class, org.hibernate.boot.model.TypeContributions, is available from the following locations:

jar:file:/C:/Users/romul/.m2/repository/org/hibernate/hibernate-core/5.4.6.Final/hibernate-core-5.4.6.Final.jar!/org/hibernate/boot/model/TypeContributions.class
jar:file:/C:/Users/romul/.m2/repository/org/hibernate/orm/hibernate-core/6.0.0.Alpha2/hibernate-core-6.0.0.Alpha2.jar!/org/hibernate/boot/model/TypeContributions.class

It was loaded from the following location:

file:/C:/Users/romul/.m2/repository/org/hibernate/hibernate-core/5.4.6.Final/hibernate-core-5.4.6.Final.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.hibernate.boot.model.TypeContributions

This could be a conflict im my pom.xml?

This is my pom.xml

How i can fix it?

Answer 1

You should not specify the version of Hibernate to use as the spring-boot-starter-data-jpa dependency takes care of that.

If you run mvn dependency:tree | grep hibernate, you see that 2 versions of hibernate are included:

16:20 $ mvn dependency:tree | grep hibernate
[INFO] |  |  \- org.hibernate.validator:hibernate-validator:jar:6.0.17.Final:compile
[INFO] |  +- org.hibernate:hibernate-core:jar:5.4.6.Final:compile
[INFO] +- org.hibernate.orm:hibernate-core:jar:6.0.0.Alpha2:compile
[INFO] |  +- org.hibernate.common:hibernate-commons-annotations:jar:5.1.0.Final:compile
[INFO] +- org.hibernate:hibernate-entitymanager:jar:5.4.8.Final:compile

It seems the group id changed from org.hibernate to org.hibernate.orm, that is why Maven does not notice it is the same library.

Also the hibernate-entitymanager dependency can be removed.

Answer 2

Delete your .m2 folder in c:\users\.m2 and then run maven install it will fix your classpath problem

Answer 3

In my case, i took the following steps.

1. I deleted the .m2 folder in c:\users\ (Note its is hidden).
2. I was using spring-boot-starter-data-jpa and spring-boot-starter-data-rest so i removed the data-rest dependency completely
3. Close the project and open again (With internet connection), so the required dependency files will be downloaded again.
