repackage failed: Unable to find main class -> [Help 1]

SpringCloud项目mvn install的时候报错

repackage failed: Unable to find main class -> [Help 1]

构建显示缺少主类，就是没有springboot入口配置类

解决方法，在项目添加入口类

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class commoonApplication {
    public static void main(String[] args) {

    }
}
