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

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 服务器依赖项时，它给出错误 ##Error: Could not find or load main class io.javabrains.discoveryserver .DiscoveryServerApplication##

我尝试使用不同版本的 eureka 服务器并更新 maven 但没有用

主 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.
