I am using Jersey (2.23.1) with jersey-media-json-jackson. But that is linked against Jackson 2.5.4. But I need to use Jackson 2.6.0 (or a newer version).

How can I do this?

I tried to set it in my pom.xml:

    <dependency>
        <groupId>com.fasterxml.jackson.module</groupId>
        <artifactId>jackson-module-jsonSchema</artifactId>
        <version>2.6.0</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.6.0</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-xml-provider</artifactId>
        <version>2.6.0</version>
    </dependency>

Then jackson 2.6.0 is used. (I have also tried newer versions.)

But my rest application throws various NoSuchMethodError or ClassNotFoundExceptions, like:

org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError: com.fasterxml.jackson.jaxrs.cfg.EndpointConfigBase.<init>(Lcom/fasterxml/jackson/databind/cfg/MapperConfig;)

Is there any way to use Jersey 2.23.1 with Jackson 2.6.0 or newer? TIA!

Update 2

Here is how I enable jackson for jersey:

    register(JacksonFeature.class);
    register(JacksonXMLProvider.class);

When you want to override a version, you need to look at the pom.xml of the module. You see in the link that there are three Jackson dependencies explicitly declared

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-base</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
</dependency>

When you want to use a new version, you have a couple options to go about it. You can explicitly declare all of them in your pom.xml file with the version you want, or you can exclude all the dependencies, and just explicitly declare the main one.

For the option of explicitly declaring, you can just all the three above, specifying the version you want. Explicit declarations take precedence over transitive dependencies. So the explicitly declared ones will always be the ones pulled in, rather than the ones pulled in by Jersey.

For the option of excluding, you can exclude them from from the jersey-media-json-jackson, and just add the main one the pulls everything else in. In this case jackson-jaxrs-json-provider pulls the other two in, so you really only need to declare that one

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>2.23.1</version>
    <exclusions>
        <exclusion>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.fasterxml.jackson.jaxrs</groupId>
            <artifactId>jackson-jaxrs-base</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.7.0</version>
</dependency>

Either one of these ways should work.

What happens when you don't declare all dependencies when changing version, is that an older version jar can be pulled in transitively, and one of the newer versions tries to use some classes in that older version jar, and you end up with these kind of errors.
