Hi,

I'm currently in the process of migrating from keycloak 15 to 19 docker images (wildfly server to quarkus app). My project makes API calls to external api's during the authentication process - I used org.jboss.resteasy:resteasy-client dependency 3.11.2.Final as a provided dependency to achieve this in keycloak versions 8 - 15. Having migrated to version 19 I've bumped the version of resteasy to 4.7.4.Final as that appears to be what is in keycloak 19's pom: https://github.com/keycloak/keycloak/blob/main/pom.xml#L99.

I try instantiate an instance of the rest-client as follows:

new ResteasyClientBuilderImpl()
            .connectTimeout(X)
            .readTimeout(X)
            .connectionCheckoutTimeout(X)
            .providerFactory(ResteasyProviderFactory.getInstance())
            .useAsyncHttpEngine()
            .build();

However this results in an ERROR:

2022-10-25 10:38:40,740 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (executor-thread-6) Uncaught server error: java.lang.NoClassDefFoundError: org/jboss/resteasy/client/jaxrs/ResteasyClientBuilder
   at java.base/java.lang.ClassLoader.defineClass1(Native Method)
   at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1017)
   at io.quarkus.bootstrap.runner.RunnerClassLoader.loadClass(RunnerClassLoader.java:97)
   at io.quarkus.bootstrap.runner.RunnerClassLoader.loadClass(RunnerClassLoader.java:57)

I have loaded the resteasy-client-4.7.4.Final.jar into the providers location within the docker container.

Thanks for any help,
Andy

@AndyCa did you ever got this to work? I am facing a similar issue (although I am migrating away from `jboss-deployment-structure.xml): #16241
