java - 如何使用 Gradle 将 HiveMQ 客户端作为依赖项添加到 HiveMQ 社区版？

问题描述

我想将 HiveMQ 客户端和 HiveMQ 社区版（代理的实现）结合到一个项目中。我尝试将 HiveMQ 客户端作为依赖项添加到 Hive MQ 社区版（代理）中的 build.gradle 文件。它能够成功构建，但我不确定我是否做得正确。当我尝试在 Community Edition 中引用客户端类时，它给了我错误。我错过了什么吗？我希望能够将客户端项目放入代理社区版中，并能够创建一个客户端并访问我在 HiveMQ 客户端中可以访问的所有类。我留下了 HiveMQ 客户端网站的说明、链接以及 build.gradle 文件看起来像 HiveMQ 社区版的内容。

我得到的错误：无法解析导入 com.hivemq.client（发生在引用 HiveMQ 客户端项目中任何内容的所有导入上）
