學習亞馬遜Kinesis Streams開發 - java.lang.NoClassDefFoundError：com/amazonaws/util/json/JSONObject

我想在這裏找到的Kinesis Streams上運行以下AWS教程，http://docs.aws.amazon.com/streams/latest/dev/learning-kinesis-module-one-consumer.html，該項目的Producer部分（StockTradesWriter .java）工作得很好，但當我嘗試運行項目的Consumer部分（StockTradesProcessor.java）時，出現以下錯誤。學習亞馬遜Kinesis Streams開發 - java.lang.NoClassDefFoundError：com/amazonaws/util/json/JSONObject

所以這個類，http://javadox.com/com.amazonaws/aws-java-sdk-core/1.9.26/com/amazonaws/util/json/JSONObject.html，由於某種原因無法找到。

我在Eclipse中使用Java 8運行此操作，並且包含Kinesis客戶端庫（KCL）版本1.6.3和適用於Java版本1.11.7的AWS開發工具包。這裏是我的Eclipse項目的屏幕截圖：
