Embedded Kafka test cases are error after adding jsonschema2pojo-core - spring-kafka

Question

I have an application that created with Spring boot and Spring kafka libraries. Now I added jsonschema2pojo-core library to my pom file. After adding this jar file my test cases are failing with below error
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedKafka': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: scala/runtime/java8/JFunction0$mcZ$sp

Answer 1

It's probably similar to this https://docs.spring.io/spring-kafka/docs/2.5.11.RELEASE/reference/html/#jacksonscala-incompatibility
with the library pulling in an incompatible scala library.
Yes, adding
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>2.12.11</version>
</dependency>
fixed it for me; but I can't guarantee that jsonschema2pojo will work with that version.
The scala folks are notorious for breaking API changes in patch releases.
