After upgrading to Spring Boot 2.2.4, I have a strange compilation error:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jacksonObjectMapper' defined in class path resource [org/springframework/boot/autoconfigure/jackson/JacksonAutoConfiguration$JacksonObjectMapperConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.fasterxml.jackson.databind.ObjectMapper]: Factory method 'jacksonObjectMapper' threw exception; nested exception is java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)[Ljava/lang/Object;

I have no scala dependency in my classpath.

Running a gradlew dependencies --configurationruntimeClasspath gives me:

  • You must have a Scala dependency, otherwise the class on which there's no such method would not have been loaded. I'd guess it's a transitive dependency of something that you do depend upon. Can you share your dependency tree (`./mvnw dependency:tree` or `./gradlew dependencies --configuration runtimeClasspath`)? – Andy Wilkinson Jan 21 '20 at 15:04

  • You have several Scala dependencies, both a direct one and some that are pulled in via Kafka. There appears to be a mixture of versions (2.3.1 and 2.4.0) which may be contributing to the problem. I'd recommend reviewing your `build.gradle` and tidying up your dependencies. If that doesn't help, please update the question with a [minimal, complete, and verifiable example](/help/mcve). – Andy Wilkinson Jan 21 '20 at 16:11

You have several Scala dependencies, both a direct one and some that are pulled in via Kafka. There appears to be a mixture of versions (2.3.1 and 2.4.0) of Spring Kafka which may be contributing to the problem. I'd recommend reviewing your build.gradle and tidying up your dependencies so that you’re using a consistent set of versions.

Andy was right. We do have some problems of mixing dep versions. Details can be found here:

https://docs.spring.io/spring-kafka/reference/html/#deps-for-24x

Specifically, we do this:

dependencies {
    compile 'org.scala-lang:scala-library'
    compile ('org.springframework.kafka:spring-kafka-test') {
        exclude module: 'kafka_2.11'
    }
    compile 'org.apache.kafka:kafka-clients:2.4.0'
    compile 'org.apache.kafka:kafka-clients:2.4.0:test'
    compile 'org.apache.kafka:kafka_2.12:2.4.0'
    compile 'org.apache.kafka:kafka_2.12:2.4.0:test'
    ...
}
