Problem Description

The FAQ section https://github.com/oracle/helidon/wiki/FAQ#how-do-i-use-jackson-in-helidon-mp does not provide a complete answer on how to make Jackson work when using helidon-microprofile bundles artifact as a dependency. This issue: #3198 actually provides answer on what dependency within the bundle needs to be excluded. In my testing adding jersey-media-json-binding and excluding jersey-media-json-binding from helidon-microprofile bundles dependency made it work, even though the issue also suggests excluding jakarta.json.bind-api and yasson. Maybe we can add in the FAQ that if helidon-microprofile bundles artifact is used, then we need to add exclusion like this:

<dependency>
    <groupId>io.helidon.microprofile.bundles</groupId>
    <artifactId>helidon-microprofile</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-binding</artifactId>
        </exclusion>
        <exclusion>
            <groupId>jakarta.json.bind</groupId>
            <artifactId>jakarta.json.bind-api</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.eclipse</groupId>
            <artifactId>yasson</artifactId>
        </exclusion>
    </exclusions>
</dependency>
