我正在尝试按照本教程http://docs.neo4j.org/chunked/milestone/server-plugins.html创建服务器插件

我在eclipse中创建了一个maven项目(按照本教程http://blog.neo4j.org/2012/03/how-to-set-up-maven-project-with-neo4j.html)并添加了必要的依赖项从我在 pom.xml 和 maven 依赖项列表中实际看到的 maven 存储库中,然后我使用目标“干净安装”创建了我的 jar,并将其添加到 neo4j 插件中。

后一个插件已正确添加,我可以通过以下方式进行检查:

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

但奇怪的是,当我尝试从 shell 运行它时出现以下错误:

我确信在创建 jar 时确实添加了依赖项(我使用:mvn dependency:tree -Dverbose进行了检查,并且还添加了包含此类的包“org.lucene.lucene-spellchecker”

任何帮助将非常感激。

谢谢

jar tf file如果 lucene 类真的在里面,你能检查一下 jar 文件吗?

你是用 mvn assembly single 创建的吗?

您还可以使用mvn dependency:copy-dependencies这些额外的 jar 文件并将其复制到服务器安装的 plugins 文件夹中。
