我正在尝试使用Intellij Ultimate（Java 1.8，Maven 3.5.4，Spring 2.0.4）创建一个使用Spring Boot的项目。这是我的第一个Spring Boot项目，所以我不确定我是否正确地使用了Maven。
我已经尝试过从此链接编辑pom文件并添加依赖项（spring-boot-starter-data-jpa，spring-boot-starter-web）的建议，但仍然无法解决问题。 package org.springframework.boot does not exist 我一直收到以下错误提示：
我使用Spring Initializer创建了这个项目并保留了所有默认设置，但是它无法构建。

以下是我的代码/ Java类：
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);
}
}
我使用Spring Initializer创建了这个项目并保留了所有默认设置，但是它无法构建。
