私はelasticsearchに慣れ親しんで、Java APIを使って基本的なプログラムを作成しようとしています。私はしばらくの間、答えを研究してきましたが、私が誤って見つけた解決策を実行しているのか、本当の問題を見ていないのか分かりません。Elastic Search java.lang.NoClassDefFoundError：org/elasticsearch/transport/Netty3Plugin
私はelasticsearch-5.1.1を使用していて、最新のトランスポートバージョン（5.1.1）をダウンロードしました。私はまた、私のプロジェクト構造の中にelasticsearchダウンロードに付属しているすべてのjarファイルを含む両方を追加しました。
ありがとうございます！
テストファイルを実行しているときに、次のエラーが発生しています。
エラー：私は私のpom.xmlファイルに次の依存関係を追加し、与えられたdirectionsを次xpackをインストールしている
