NoSuchMethodError in Spring Batch: ItemWriter.write(java.util.List) kann nicht aufgerufen werden ⇐ Java

[Guest]

Hallo, ich bin neu bei Spring Batch und versuche, ein einfaches Batch-Programm zu erstellen, das Daten von einer CSV-Datei in eine andere überträgt und dabei den Namen in Großbuchstaben umwandelt. Das Lesen und Verarbeiten der Daten scheint in Ordnung zu sein, aber beim Schreiben bekomme ich einen Fehler und Ich scheine das Problem nicht zu finden
Hier sind einige Screenshots, Ergebnisse und Code
