title: Issue with Spring application, basend on spring.io tutorial
body: <p>I'm trying to learn Spring framework so I decided to follow tutorials available on <code>Spring.io</code> website. I have an issue in my application with the chapter: <a href="http://spring.io/guides/gs/rest-service/" rel="nofollow noreferrer">http://spring.io/guides/gs/rest-service/</a></p>
  
  <p>I did it with friend day before and app worked and is still working. I tried to do it on my own and in main class I receive error:</p>
  
  <p><strong>Error Stack Trace</strong></p>
  
  <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
      The type org.springframework.context.ConfigurableApplicationContext cannot be resolved. It is indirectly referenced from required .class files
      The method run(Object, String...) from the type SpringApplication refers to the missing type ConfigurableApplicationContext 
  </code></pre>
  
  <p>I'm trying to do it at my company office right now, can security software in my company's broadband be at fault?</p>
  
  <p>Main class: <strong>Application.java</strong></p>
  
  <pre><code>package hello;
  
  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  
  @SpringBootApplication
  public class Application {
  
          public static void main(String[] args) {
          SpringApplication.run(Application.class, args);
     }
  }
  </code></pre>
