Maven Keycloak library wirft exceptions nach maven package

[bob_sheknowdas]

Hi,

ich habe mit der java Keycloak libarary ein bisschen Code geschrieben.
Der läuft in Eclipse problemlos. Wenn ich aber ein jar-File erzeuge, fliegen Exceptions...

Hier der Code (senden von Benutzernamen und Passwort an Keycloak und empfangen eines JWT)

import org.keycloak.OAuth2Constants;
import org.keycloak.admin.client.Keycloak;
import org.keycloak.admin.client.KeycloakBuilder;
import org.keycloak.representations.AccessTokenResponse;

public class ServiceMainClass {

    public static void main(String[] args) {

        String jwt = retrieveJWT();
        System.out.println(jwt);

    }

    private static String retrieveJWT() {
        Keycloak keycloak = KeycloakBuilder.builder() //
                .realm("VertxTestRealm") //
                .serverUrl("http://localhost:8085/auth")//
                .clientId("VertxTestClient") //
                .clientSecret("f230275b-61e8-4d5f-8bbd-276a77a1d5f1") //
                .username("MeinName") //
                .password("MeinPasswort") //
                .grantType(OAuth2Constants.PASSWORD).build();

        AccessTokenResponse tokenResponse = keycloak.tokenManager().getAccessToken();
        String token = tokenResponse == null ? null : tokenResponse.getToken();
        return token;
    }

}

Die Exception sieht so aus:
