We have a custom UserStorageProvider that needs to communicate to an external API. We use resteasy-client for this.

In legacy, you could do:

        <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-client</artifactId>
            <version>4.7.4.Final</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.jaxrs</groupId>
            <artifactId>jackson-jaxrs-json-provider</artifactId>
            <scope>provided</scope>
        </dependency>

And provide a jboss-deployment-structure.xml like so:

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-client" services="export"/>
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" services="export"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

However, under Quarkus this gives ClassNotFoundExceptions. If you however include the resteasy-client dependencies within the uber-jar of the extension, Keycloak doesn't start up at all.

How can resteasy-client be used in Quarkus extensions from version 18 and onward?

I found in the release notes that:

With the new distribution there is no longer a separate classpath for custom providers, so you may need to be more careful with what additional dependencies you include. In addition, the EAR packaging format, and jboss-deployment-structure.xml files, is no longer supported.

However, no migration path is suggested, so this provide little insight in how to actually rewrite/implement extensions as of yet.

I eventually got it to work by copying the following JARs to the deployments folder:

providers/resteasy-client-4.7.4.Final.jar
providers/resteasy-client-api-4.7.4.Final.jar
providers/wildfly-client-conf 8000 ig-1.0.1.Final.jar

I am still somewhat sceptical about this approach.
