title: Spring Boot with spring-boot-starter-web fails to compile in maven
body: <p>I am using jdk1.7 and spring boot 1.4.2.Release.I created a brand new Spring boot project from start.spring.io. It compiled fine. I tried to add the below dependency for exposing a REST web service.</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
      &lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>I get the below error:</p>
  
  <pre><code>[ERROR] Failed to execute goal on project demo: Could not resolve 
  dependencies for project com.example:demo:jar:0.0.1-SNAPSHOT: Failed to

  <p>It takes the <a href="http://repo.spring.io/ext-release-local" rel="nofollow noreferrer">http://repo.spring.io/ext-release-local</a> link which does not have jboss related files.</p>
  
  <p>Please let me know if I am doing something wrong.</p>
