如果我们使用maven添加添加“ spring-cloud-netflix-eureka-server”依赖项，springboot会给出错误“找不到或加载主类”

Question

当我在没有Eureka服务器的情况下运行spring-boot应用程序时，它成功运行，但是当我使用maven在pom.xml文件中添加Eureka服务器相关性时，它给出错误## Error：无法找到或加载主类io。 javabrains.discoveryserver.DiscoveryServerApplication ##

我尝试了不同版本的eureka服务器并更新了Maven，但没有用

主要Java文件

package io.javabrains.discoveryserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;


@SpringBootApplication
@EnableEurekaServer
public class DiscoveryServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DiscoveryServerApplication.class, args);
    }

}




i expect to run this application using successfully for the Eureka server.
