Starten eines Vaadin-Projekts mit Maven fehlgeschlagen

Question

Ich versuche, Vaadin installiert zu bekommen, und starten das Tutorial, das ich finde: Ich bekomme den Fehler unten, wenn ich den mvn-Befehl ausführen.

Ich bevorzuge es normalerweise, die Jars manuell herunterzuladen und sie mit meinem Projekt in Eclipse zu verknüpfen, ohne auf öffentliche Repositories angewiesen zu sein. Ich sah andere Fragen und Antworten, die auf https://vaadin.com/download zeigten, aber diese Verbindung jetzt umleiten zu https://vaadin.com/framework/get-started

Irgendwelche Ideen, wie man anfängt?
