为什么我在amazon-kinesis-client中的JSONObject上获得NoClassDefFoundError？

Question

我已将来自aws-dynamodb-examples的DynamoDB流适配器演示的代码合并到我的Maven项目中,并且我遇到了运行时错误:

Exception in thread "Thread-2" java.lang.NoClassDefFoundError: com/amazonaws/util/json/JSONObject
at com.amazonaws.services.kinesis.leases.impl.Lease.toString(Lease.java:229)

知道为什么会这样,以及我可以做些什么来修复它？

我的pom文件是这样的:

如果我更改aws-java-sdkto 的版本,问题就解决了1.10.77.似乎1.11.0版本中的kinesis库正在尝试使用已从中删除的JSONObject com.amazonaws.util.json.
