Keycloak: how to delete and edit a Group

Question

I already tried a bunch of different ways and none of them work.

(First of all im using this, and works with other methods, like create/delete user, create group etc etc)

public void startKeycoak(String username, String password) {
    Keycloak kc = KeycloakBuilder.builder()
            .serverUrl(uri)
            .realm(realmName)
            .username(username)
            .password(password)
            .clientId(client)
            .resteasyClient(
                    new ResteasyClientBuilder()
                            .connectionPoolSize(10).build())
            .build();

    this.kc = kc;
}

Problem starts here:

public void deleteGroup(String groupName) {
    GroupRepresentation groupRepresentation = kc.realm(realmName)
            .groups()
            .groups()
            .stream()
            .filter(group -> group.getName().equals(groupName)).collect(Collectors.toList()).get(0);


    //  kc.realm(realmName).groups().group(existingGroups.getName()).remove(); -> Not Working 

  //  boolean a = kc.realm(realmName).groups().groups().remove(groupRepresentation); -> Not Workings - returns a false
}

    public void updateGroup(String newName, String oldName) {
        GroupRepresentation groupRepresentation = kc.realm(realmName)
                .groups()
                .groups()
                .stream()
                .filter(group -> group.getName().equals(oldName)).collect(Collectors.toList()).get(0);

        //groupRepresentation.setName(newName);  -> 1 - Not working

        //kc.realm(realmName).groups().groups().stream().filter(g -> {  -> 2 - Not Working
            //g.setName(oldName);
            //return false;
        //});
    }

Like I said before its working with a lot of methods except those two.

Answer 1

kc.realm(realmName).groups().group(groupRepresentation.getId()).remove();

try to delete it with the group representation id it works.
