Java Elasticsearch7.3中SpringBoot的NoClassDefFoundError异常

我尝试通过以下高级rest客户端创建文档：

    Map<String, Object> jsonMap = new HashMap<>();
    jsonMap.put("name", "Bob");
    jsonMap.put("id", "123456");
    IndexRequest indexRequest = new IndexRequest("lead").id("123456").source(jsonMap);
    client.index(indexRequest, RequestOptions.DEFAULT);

maven依赖关系树：

---

我已经找到了错误的原因。这个项目中还有另一个依赖项，包括3.5.0版本的

lucene core.jar

。它与elasticsearch中的8.1.0版本

lucene core.jar

冲突。程序运行时实际上使用的是3.5.0版本。

您能分享一下应用程序的maven依赖树吗？您好，我已经上传了maven依赖树作为链接。@Ramu
