How to make sure Spring Boot extra Jackson modules are of same version?

Question

Spring Boot already contains the core Jackson dependency + several others.

If you e.g. want to add the org.json or jsr-353 databinding modules you to explicitly define the vesion of these additional modules.

Is there a way to refer to the same version of the other Jackson modules? I want to avoid any compatibility issues.

Answer 1

Spring Boot provides managed dependencies for the following Jackson modules:

• jackson-annotations
• jackson-core
• jackson-databind
• jackson-datatype-joda
• jackson-datatype-jsr310

If you're using maven then additional modules could be defined in your own POM using the ${jackson.version} property. eg:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-whatever</artifactId>
    <version>${jackson.version}</version>
</dependency>

Answer 2

In Gradle just add ext['jackson.version'] = 'specify version here' before dependencies section.
