无法从start.spring.io启动Spring Boot 2x应用程序

Question

当我尝试启动spring boot应用程序时，我得到了NoClassDefFoundError异常。afaik这是一个依赖问题，但我无法解决它。

下面是stacktrace：

应用程序代码就是运行spring应用程序：

package com.example.demo7;

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

@SpringBootApplication
public class Demo7Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo7Application.class, args);
    }
}

这个问题只出现在Boot2x上，1.5运行得很好，我找不到谷歌的类似问题。
