在此输入图片描述

一切都好！

但是我遇到了上面的错误！

并且该错误（由于 ClassNotFoundException 导致的错误：org.elasticsearch.common.xcontent.XContentFactory）不在 google 上

请帮助我！我不知道我必须做什么。

我做到了

1. 检查 Windows 上的 java_home

2. 检查intelliJ sdk

3. 谷歌搜索

您能否检查一下 build.gradle 文件中的 elasticsearch 依赖项（如果存在）。除此之外，您可以点击Intellij右上角Gradle的刷新按钮（假设您正在使用它），请检查File->Project Structure->Libraries

中是否包含库

这个类通常应该在这里：https://artifacts.elastic.co/javadoc/org/elasticsearch/elasticsearch-x-content/7.6.0/index.html
