Object Mapper - YAMLFactory - exception due to missing _createContentReference method

Question

I'm using the latest 2.13.0 version of jackson, and when I try to parse a YAML file, I'm getting this exception

 java.lang.NoSuchMethodError: 'com.fasterxml.jackson.core.io.ContentReference com.fasterxml.jackson.dataformat.yaml.YAMLFactory._createContentReference(java.lang.Object)'

What could be the issue?

The dependencies that I've included are jackson-core, jackson-databind and jackson-dataformat-yaml - all 2.13.0

Answer 1

No such method error in most cases means that you have have 2 dependencies that are the same but with different versions, however the application is loading the version that does not have this method in it,

The reference to this _createContentReference exists in YAMLFactory in jackson-dataformat-yaml.jar

The actual _createContentReference implementation exists in com.fasterxml.jackson.core.JsonFactory which exists jackson-core.2.13.0.

In your case, you probably have another jackson-core.jar with an older version as part of your indirect dependencies.

You can see mvn dependency:tree or your IDE (Such as Eclipse allows you to search for dependency by name, and it returns all that match, including their versions)

Thanks. It helped me to exclude jackson-dataformat-yaml version 2.13.1 from quarkus-smallrye-openapi and include 2.12.3 . Like this :

    <dependency>
        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-smallrye-openapi</artifactId>
        <exclusions>
            <exclusion>
                <groupId>com.fasterxml.jackson.dataformat</groupId>
                <artifactId>jackson-dataformat-yaml</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-yaml</artifactId>
        <version>2.12.3</version>
    </dependency>

The same problem I also faced. My environment is - Wildfly version - 26.1.1-Final Spring boot - 2.7.8

The issue is coming because Wildfly has the same version API already added as module and the same set of jackson* series jars are going thourgh spring boot hence on runtime it is creating issue.

Solution - all jackson* jar under spring-boot pom.xml add into exclusion list and separtly added dependencies with scope provied. My modified pom.xml is as below -

<properties>
    <spring.boot.version>2.7.8</spring.boot.version>
    <jackson.version>2.13.4</jackson.version>       
</properties>

Ran into the same problem with spring boot 3, gradle and org.openapi.generator plugin 7.3.0. Problem was caused by the openapi plugin using an ancient version of jackson-core (2.12.x) under the hood for any reason, despite its pom says jackson-core 2.15.3 and my project definitely uses the same version.

The following entry (in the root build.gradle) forces the plugin to use the newer version and worked for me:

buildscript {
  dependencies {
    classpath 'com.fasterxml.jackson.core:jackson-core:2.15.3'
  }
}
