Hi, i am trying to use the java keycloak-admin-client to access my keycloak server. Dependencies: compile group: 'org.jboss.resteasy', name: 'resteasy-jackson-provider', version: '3.1.2.Final' compile group: 'org.jboss.resteasy', name: 'resteasy-multipart-provider', version: '3.1.2.Final' compile group: 'org.jboss.resteasy', name: 'resteasy-client', version: '3.1.2.Final' compile group: 'org.keycloak', name: 'keycloak-admin-client', version: '3.1.0.Final' When i use the client to get the server info i get this exception: Exception in thread "main" javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "access_token" (Class org.keycloak.representations.AccessTokenResponse), not marked as ignorable at [Source: org.apache.http.conn.EofSensorInputStream@68e5eea7; line: 1, column: 18] (through reference chain: org.keycloak.representations. AccessTokenResponse["access_token"]) Here is my code: Keycloak kc = KeycloakBuilder.builder() .serverUrl("http://<mykeycloak>/auth") .realm("master") .username("admin") .password("admin") .clientId("admin-cli") .resteasyClient( new ResteasyClientBuilder().connectionPoolSize(10).build() ).build(); System.out.println(kc.serverInfo().getInfo()); What am i doing wrong?
