[keycloak-user] Keycloak extension wiith admin-client

Hi everyone, we try to build an additional keycloak REST endpoint that should use the admin client. Therefore in my code I copied the example from keycloak github and added: Keycloak kc = KeycloakBuilder.builder() .serverUrl("https://localhost:8080/auth") .realm("master") .username("admin") .password("admin") .clientId("admin-cli") .resteasyClient( new ResteasyClientBuilder() .connectionPoolSize(5).build() ).build(); When I put my jar into standalone/deployments first it does not find KeycloakBuilder. So I had to deploy keycloak-admin-client-4.0.0.Beta3.jar as a module manually. In "/opt/jboss/keycloak/modules/system/layers/keycloak/org/keycloak" seem to be lots of modules but keycloak-admin-client is missing. After manually deployment of the keycloak-admin-client as a module, I added a jboss-deployment-structure.xml to my extension with: <jboss-deployment-structure> <deployment> <dependencies> <module name="org.keycloak.keycloak-admin-client" /> </dependencies> </deployment> </jboss-deployment-structure> When I hot-deploy my REST extension now I get 09:53:29,655 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-1) Uncaught server error: java.lang.IllegalArgumentException: interface org.keycloak.admin.client.token.TokenService is not visible from class loader By the way, the same errors returns when I go the long way and build a module.xml and deploy my extension with the standalone.xml Any suggestions how to solve that? Thanks and kind regards Spike
