title: Spring security oauth2 'dependencies.dependency.version' is missing for spring boot 2.0.3
body: <p>I try to add dependency of spring security.
  This is my pom.xml</p>
  
  <pre><code>&lt;properties&gt;        
      &lt;spring-boot.version&gt;2.0.3.RELEASE&lt;/spring-boot.version&gt;
  &lt;/properties&gt;
  
  &lt;dependencyManagement&gt;
      &lt;dependencies&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
              &lt;artifactId&gt;spring-boot-dependencies&lt;/artifactId&gt;
              &lt;version&gt;${spring-boot.version}&lt;/version&gt;
              &lt;type&gt;pom&lt;/type&gt;
              &lt;scope&gt;import&lt;/scope&gt;
          &lt;/dependency&gt;
      &lt;/dependencies&gt;
  &lt;/dependencyManagement&gt;
  
  &lt;dependencies&gt;
      ...
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-security&lt;/artifactId&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.security.oauth&lt;/groupId&gt;
          &lt;artifactId&gt;spring-security-oauth2&lt;/artifactId&gt;
      &lt;/dependency&gt;
      ...
  &lt;dependencies&gt;
  </code></pre>
  
  <p>I try with artifactId spring-security-oauth2, it said: 
  'dependencies.dependency.version' for org.springframework.security.oauth:spring-security-oauth2:jar is missing</p>
  
  <p>but with spring 1.4.2.RELEASE, It work.
  What is the new spring security oauth2 maven repo for springboot 2.0.3.RELEASE? (without  element)
  Thanks</p>
