「的NoClassDefFoundError」在行家

Question

我試圖按照本教程http://docs.neo4j.org/chunked/milestone/server-plugins.html

我創建了一個Maven項目（以下本教程http://blog.neo4j.org/2012/03/how-to-set-up-maven-project-with-neo4j.html）的日食，並從Maven倉庫添加必要的依賴，以創建一個服務器插件，我在pom.xml和maven依賴列表中看到了實際的內容，然後我使用目標「clean install」創建了我的jar，並將它添加到neo4j插件中。

後者插件已正確添加，我可以檢查感謝：

curl -v http://localhost:7474/db/data/ 

但令人奇怪的是，我得到下面當我嘗試從shell中運行它的錯誤：

我相信當jar被創建時我真的添加了依賴項（我使用：mvn dependency：tree -Dverbose和檢查了包含此類的包「org.lucene.lucene-spellchecker」） ）

任何幫助將非常感激。

謝謝

CCAN你如果Lucene的類檢查jar文件與jar tf file真的在那裏？

您是否使用mvn assembly創建它？

你還可以做的是使用mvn dependency:copy-dependencies並將這些額外的jar文件複製到服務器安裝的plugins文件夾中。
