title: Usage of '${spring.version}'
body: <p>When I use:</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;dependency&gt;
      &lt;groupId&gt;org.springframework&lt;/groupId&gt;
      &lt;artifactId&gt;spring-context&lt;/artifactId&gt;
      &lt;version&gt;${spring.version}&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  <p>on the console I get the following error message:</p>
  <blockquote>
  <p>'dependencies.dependency.version' for org.springframework:spring-context:jar must be a valid version but is '${spring.version}'. @ line 40, column 19</p>
  </blockquote>
  <p>Do I have to do a manually configuration of Maven? I've seen this kind of dependency but there is no explanation how to do it properly.</p>
