KeyCloak Admin client NoClassDefError

Configuring the server
1

I’m getting error in creating admin client in java:

keycloakClient = KeycloakBuilder.builder() //
                    .serverUrl(KC_ADMIN_CLIENT_SERVER_URL) //
                    .realm(KC_ADMIN_CLIENT_REALM) //
                    .grantType(OAuth2Constants.CLIENT_CREDENTIALS) //
                    .clientId(KC_ADMIN_CLIENT_ID) //
                    .clientSecret(KC_ADMIN_CLIENT_SECRET) //
                    .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
                    .build();
