JBoss - App deployment ignoring fasterxml exclusions

Question

I've got an app deployed to a JBoss 7.2 instance that's explicitly using a defined fasterxml.jackson library: 'com.fasterxml.jackson.core:jackson-databind:2.12.6' However during runtime, I'm getting an error for a different version of jackson: 2.9.10.4-redhat-00001. The one that's loaded as a JBoss Module.

How do I exclude this from being used by the app completely? I've performed the following and none seem to work:

1. Excluding all other jackson libraries from being pulled down from maven.
2. Forcing the correct jackson library into the WAR/lib folder during the build.
3. Calling out all jackson libraries as <exclusion></exclusion> in the jboss-deployment-structure.xml
4. I even went as far as converting the app to use jackson codehaus but still the error for jackson:2.9.10.4-redhat-00001 persists.

Error

Answer 1

Try to exclude the jackson default implementation via jboss-deployment-structure.xml:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-databind" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>
