Ich hoffe, jemand kann mir mit diesem seltsamen helfen. Ich versuche, das Webstart-Plugin auszuführen, aber es scheint nicht in der Lage zu sein, die Hauptklasse innerhalb des Jars zu finden, das produziert wird. Der Pom ist so einfach wie es nur geht und die Klasse Test existiert und wird kompiliert und in den Jar gelegt. Kann mir bitte jemand in die richtige Richtung zeigen?Maven webstart plugin keine Abhängigkeiten zu finden

Bitte nehmen Sie sich etwas Zeit, um Ihre Frage, die derzeit nicht lesbar ist, zu formatieren und zu erklären, was Sie erreichen wollen **. Das Webstart-Plugin hat viele Ziele. "Ich versuche den Webstart pluign auszuführen" ist nicht klar, selbst wenn ich sehen kann, welches Ziel Sie aufrufen. Das Problem ist, dass Sie Konzepte mischen, so dass ich nicht weiß, was Sie versuchen zu tun. Wie gesagt, nehmen Sie sich etwas Zeit, um zu klären und Ihre Frage klug zu stellen (http://catb.org/~esr/faqs/smart-questions.html). –
