Build Error

Inizia con pom.xml e il comando mvn clean compile exec:java, quindi esamina la chiamata S3 in S3Sample.java:86 insieme a entrambi gli errori segnalati. Riproduci gli errori di build ed esecuzione nell'ambiente documentato; il lavoro è completato quando l'esempio viene compilato ed eseguito senza gli errori segnalati di compatibilità Java o di classe mancante.

Very new to programming and AWS SDK Java... Just getting started..

After following all the instructions am getting still the Build Failure still.
