我从github.com下载netty-socketio-demo，我不能mvn install服务器，我收到错误

我在mvn存储库中找到了依赖项。我使用命令mvn clean install。谢谢你的帮助。

Answer 1

更改server文件夹的pom.xml：

<dependency>
   <groupId>com.corundumstudio.socketio</groupId>
   <artifactId>netty-socketio</artifactId>
   <version>1.7.1</version>
</dependency>

要：

<dependency>
   <groupId>com.corundumstudio.socketio</groupId>
   <artifactId>netty-socketio</artifactId>
   <version>1.6.5</version>
</dependency>

重新运行maven

我的mavenning install netty-socketio-demo出了什么问题？
