未找到PrebuiltTransportClient org.elasticsearch.transport.Netty3Plugin类

Question

所以这个Elasticsearch项目真的踢我的屁股。我的最新问题是在执行

时

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY);

我收到此错误：java.lang.ClassNotFoundException：org.elasticsearch.transport.Netty3Plugin。完整的堆栈跟踪：

之前有没有人处理过这个错误，如果有的话，我该怎么办？谢谢你的帮助。

编辑1＆amp; 2：

经过一些进一步测试后，我发现刷新页面后第一个错误被此错误替换。这是它的堆栈跟踪。
