我正在处理一个现有的项目，它应该是工作正常，没有问题，第一步我想做的是运行它在本地，但我有这个错误：

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
    SpringApplicationBuilder cannot be resolved to a type

我不能发布所有的代码，因为它是非常巨大的，但这里是导致错误的代码，与作者注意：

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.annotation.PropertySources;

/**
 * The main application class which bootstraps all configuration and runs the
 * application. This class can be run standalone (e.g. in Eclipse, Run As ->
 * Java Application), which start an embedded Tomcat webserver, or it can be
 * deployed as a WAR in an existing container.
 * 
 * @author
 * 
 */
@SpringBootApplication
public class Application extends SpringBootServletInitializer
{
    public static void main(final String[] args)
    {
        new SpringApplicationBuilder(Application.class).showBanner(false).run(args);
    }

我正在做作者提到的;
Eclipse，运行方式-〉* Java应用程序）。
但是得到上面的错误，我做错了什么？我克隆了所有的项目，也许我丢失了一些库包？不应该在同一个源，我克隆的地方？
