我想通過使用java api編寫一個基本程序來熟悉elasticsearch。我一直在研究一個答案，但我不確定是否正在執行我發現不正確的解決方案，或者只是沒有看到真正的問題。彈性搜索java.lang.NoClassDefFoundError：org/elasticsearch/transport/Netty3Plugin
我使用elasticsearch-5.1.1並下載了最新的傳輸版本（5.1.1）。我也在項目結構中添加了兩個（包括隨elasticsearch下載一起提供的所有jar文件）。
在此先感謝！
運行我的測試文件時，出現以下錯誤。

我已經添加了以下依存關係到我的pom.xml文件和安裝xpack下面給出directions。我的pom.xml與我的log4j2.xml文件一起位於src/lib中。
