MongoDB - 未找到 MongoClientURI ...（使用 maven）

Question

我正在创建一个 Minecraft Java 插件，但我遇到了一个错误，尽管尝试了很多次，我还是找不到解决方案。我试图遮蔽，用依赖项等编译.jar。我不知道该怎么办。

错误是“java.lang.NoClassDefFoundError: com/mongodb/MongoClientURI”。

这是错误

对不起，我的英语不好。这不是我的第一语言。

后来的 Mongo Driver 移除了对 MongoClientURI 的支持，但是你可以通过这个依赖找到它

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-legacy</artifactId>
    <version>3.12.10</version>
    <scope>compile</scope>
</dependency>
