Learning Amazon Kinesis Streams Development - java.lang.NoClassDefFoundError: com/amazonaws/util/json/JSONObject

Question

我正在尝试运行此处找到的关于 Kinesis Streams 的以下 AWS 教程，http://docs.aws.amazon.com/streams/latest/dev/learning-kinesis-module-one-consumer.html，项目的生产者部分 (StockTradesWriter.java) 工作正常，但我'当我尝试运行项目的消费者部分 (StockTradesProcessor.java) 时出现以下错误。

所以这个 class，http://javadox.com/com.amazonaws/aws-java-sdk-core/1.9.26/com/amazonaws/util/json/JSONObject.html，由于某种原因找不到。

我在 Eclipse 中运行使用 Java 8 进行此操作，我已经包含了 Kinesis Client Library (KCL) 1.6.3 版和 [=30= 的 AWS SDK ] version 1.11.7.Here 是我的Eclipse项目截图：

注意：要下载并运行此程序，您可以在此先决条件页面上找到所需的一切：http://docs.aws.amazon.com/streams/latest/dev/learning-kinesis-module-one-begin.html

Answer 1

显然最新的 AWS SDK (1.11.x) 不适用于本教程。我将版本降到 1.10.76，一切都开始工作了……谢谢亚马逊。

Answer 2

升级到 KCL v1.7.2 似乎已经为我解决了这个问题。我正在使用 AWS SDK 1.11.58。

不确定问题是何时引入或修复的
