body: <p>we are trying to take advantage of spring-boot-actuator to retrieve build info through /info endpoint i'm getting empty "{}" object as response these are my pom configurations</p>
  
  <pre><code>&lt;parent&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
          &lt;version&gt;1.3.1.RELEASE&lt;/version&gt;
  &lt;/parent&gt;
  
  &lt;dependency&gt;
              &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
              &lt;artifactId&gt;spring-boot-starter-actuator&lt;/artifactId&gt;
              &lt;version&gt;1.4.0.RELEASE&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>i made sure build-info. properties is created in my target/META-INF/classes folder through build-info goal </p>
  
  <pre><code>&lt;build&gt;
          &lt;plugins&gt;
              &lt;plugin&gt;
                  &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
                  &lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
                  &lt;version&gt;1.4.0.RELEASE&lt;/version&gt;
                  &lt;executions&gt;
                      &lt;execution&gt;
                          &lt;goals&gt;
                              &lt;goal&gt;build-info&lt;/goal&gt;
                          &lt;/goals&gt;
                      &lt;/execution&gt;
                  &lt;/executions&gt;
              &lt;/plugin&gt;
          &lt;/plugins&gt;
      &lt;/build&gt;

  <p>please let me know if i'm missing anything. The end point itself seem's to be accessible  not sure if i have to do anything else as the documentation say's <a href="http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-endpoints.html" rel="nofollow">http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-endpoints.html</a> if build-info properties file is present that build-info properties by default are exposed via /info end point</p>
  
  <p>Note : we are not using application.yml in the project, also we will not be able to upgrage the starter-parent to 1.4.Release at this time</p>
