Hast du evtl auf deinem PC noch ältere Versionen von Java? die könntest du mal löschen.

 

[Malfrador]

Ich nehme an das du das Plugin mit Java 8 erstellt hast, der Server aber nur mit Version 7 läuft. Zumindest war es das Problem bei mir

 

[LoganBwDE]

Normalerweise sagt dieser Fehler, dass deine Java Version inkompatibel mit der deines Servers ist. Eine Lösung des Problems wäre, das Plugin mit Java 7 zu kompalieren.
