SpringBoot 2.1.0 throws ClassNotFoundException when trying to integrate database access

Question

I have a simple SpringBoot 2.1.0 application and try to add the database-connectivity with JPA. Everything is set up with the "spring-boot-starter-data-jpa" dependency in pom.xml, but when I start the application, I get this ClassNotFoundException.

I tried already adding byte-buddy manually as dependency, but this changes nothing.

Has someone solved this problem already?

Many thanks for every hint in advance!

And here is the database-configuration in application.yml

      ddl-auto: create-drop
  datasource:
    platform: postgres
    url: jdbc:postgresql://localhost:5432/db
    username: postgres
    password: <something>
    driverClassName: org.postgresql.Driver

If you've upgraded the spring boot version, please try to delete .m2 folder and try again. If the project is new, please add the pom file and mention which type of connector did you use - embedded or external database. — Adina Rolea, Nov 14 '18 at 19:04
take a look at [this](https://github.com/mockk/mockk/issues/80). — want2learn, Nov 14 '18 at 19:58
I updated the issue with the dependencies from pom.xml and the database-configuration (external database) — Ulrich Cech, Nov 15 '18 at 12:01
I made some further hints: The combination JDK 10.0.2 and SpringBoot 2.1.0 and JDK 11 with SpringBoot 2.0.6/2.1.0 produces these errors. — Ulrich Cech, Nov 16 '18 at 12:59

Byte Buddy is used by Hibernate. By forcing Byte Buddy into test scope, the library is now missing at runtime.

Thank you. Had the same problem and removing the test scope for ByteBuddy in the POM fixed the issue. – martin_wun Jul 11 '23 at 11:02

add dependency in pom.xml

<dependency>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy-dep</artifactId>
    <version>1.9.12</version>
</dependency>

It worked for me when I removed the folder for hibernate from the path

C:\Users\<Your user>\.m2\repository\org

Also deleted the folder net\bytebuddy

In eclipse, Right Click on the project and then Maven -> Update Project

For me helped adding the following to the module-info.java file:

requires net.bytebuddy;

This is only applicable for applications with Java 9 or higher.

For me adding as dependency in module.xml helped.

<dependencies> 
  <module name="net.bytebuddy"/> 
</dependencies>

It already comes with hibernate5 but I was not seeing the dependency.
