title: Changing pom.xml doesn't update libraries in Eclipse
body: <p>I have pom.xml like this:</p>
  
  <pre><code>...
  
  &lt;properties&gt;
      &lt;spring.version&gt;3.0.5.RELEASE&lt;/spring.version&gt;
  &lt;/properties&gt;
  
  &lt;dependencies&gt;
  
      &lt;!-- Spring 3 dependencies --&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework&lt;/groupId&gt;
          &lt;artifactId&gt;spring-core&lt;/artifactId&gt;
          &lt;version&gt;${spring.version}&lt;/version&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework&lt;/groupId&gt;
          &lt;artifactId&gt;spring-web&lt;/artifactId&gt;
          &lt;version&gt;${spring.version}&lt;/version&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework&lt;/groupId&gt;
          &lt;artifactId&gt;spring-webmvc&lt;/artifactId&gt;
          &lt;version&gt;${spring.version}&lt;/version&gt;
      &lt;/dependency&gt;
  
  ...
  </code></pre>
  
  <p>When I change <code>spring.version</code> into 3.2.2.RELEASE, nothing happens. I still have 3.0.5.RELEASE under Libraries build path.</p>
  
  <p>I am using Eclipse Indigo SR2 with m2eclipse.</p>
  
  <p>EDIT: Please mind, I am a newbie in maven world.</p>
