在intellij idea中创建spring引导应用程序后，它出现了错误。我没有编辑代码。它找不到org.spring.boot.springapplication。我已经尝试创建应用程序好几次，但没有效果。所有需要的插件都在ide中，已打开。也许有人已经有问题了
代码中的错误

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

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

}

控制台中的错误
