title: How do I get my Eclipse-Maven project to automatically update its classpath when I change a dependency in my pom.xml file?
body: <p>I’m using Eclipse Mars with Maven (v 3.3).  When I update a dependency in my pom (change the version), my Eclipse-Maven project doesn’t pick it up, even when I right click my project, and select “Maven” -> “Update Project.”  I know this because I do not see compilation errors in the Eclipse Java editor that I see when I build the project on the command line using</p>
  
  <pre><code>mvn clean install
  </code></pre>
  
  <p>When I remove the project from the workspace and re-import it, then things get back to normal.  However this is a cumbersome process.  How do I get my Maven-Eclipse project to automatically detect changes in my pom and update the project libraries appropriately?</p>
  
  <p>And yes, in the “Project” menu, “Build Automatically” is checked.</p>
