Failed to index ResteasyJackson2Provider using the keycloak-admin-client-reactive extension

[jorsol]

Describe the bug

The quarkus-keycloak-admin-client-reactive extension excludes dependencies from classic RESTEasy including org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider.

The keycloak-admin-client dependency has a JacksonProvider class that extends ResteasyJackson2Provider.

When Quarkus is building the app, it prints a WARNING that can't index the org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider because it doesn't exist.

Expected behavior

No warning in the build output.

Actual behavior

[INFO] --- quarkus-maven-plugin:2.12.2.Final:build (default) @ viz-rest-api ---
[WARNING] [io.quarkus.arc.processor.BeanArchives] Failed to index org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider: Class does not exist in ClassLoader QuarkusClassLoader:Deployment Class Loader: PROD@3237522b
