title: Update Maven dependencies in IntelliJ Idea
body: <p>I'm new to the ​​intellij idea.</p>
  
  <p>I'm trying to add a dependency (for example) jcl-over-slf4: jar but it is not added, here is an error in the logs.</p>
  
  <pre><code>017-12-02 14: 40: 41,903 [6473161] INFO - # org.jetbrains.idea.maven - org.apache.maven.project.ProjectBuildingException: some problems occurred while processing POM:
  [ERROR] 'dependencies.dependency.groupId' for: jcl-over-slf4: jar is missing. @line 31, column 16
  </code></pre>
  
  <p>I close the Idea and deleted everything in .IntelliJIdea14\system\Maven\Indices and cleared the whole .m2\repository directory</p>
  
  <p>Restarted the Idea and in the settings I'm trying to connect to the central maven repository,  but first time it loads slowly. Now it does not load at all

  <p>I turned on auto-import and turned off the firewall and antivirus. Allowed access to the Internet. Set VM  options <code>-Xmx1024m</code> But the problem remainded.

  But the size of the .m2 / repository folder is only 27 megabytes (and you need 270).</p>
  
  <p>The idea of ​​version 14.1.6.</p>
  
  <p>Here is my pom.xml</p>
  
  <pre><code>    &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    &lt;groupId&gt;spring&lt;/groupId&gt;
    &lt;artifactId&gt;spring-test-app&lt;/artifactId&gt;
    &lt;packaging&gt;war&lt;/packaging&gt;
    &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
    &lt;name&gt;spring-test-app Maven Webapp&lt;/name&gt;
    &lt;url&gt;http://maven.apache.org&lt;/url&gt;
    &lt;dependencies&gt;

        &lt;artifactId&gt;junit&lt;/artifactId&gt;
        &lt;version&gt;3.8.1&lt;/version&gt;
        &lt;scope&gt;test&lt;/scope&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
        &lt;groupId&gt;org.springframework&lt;/groupId&gt;
        &lt;artifactId&gt;spring-webmvc&lt;/artifactId&gt;

      &lt;/dependency&gt;
  
      &lt;dependency&gt;
        &lt;groupId&gt;org.springframework&lt;/groupId&gt;
        &lt;artifactId&gt;spring-context&lt;/artifactId&gt;
          &lt;version&gt;4.3.11.RELEASE&lt;/version&gt;
      &lt;/dependency&gt;
  
        &lt;dependency&gt;

            &lt;artifactId&gt;jcl-over-slf4&lt;/artifactId&gt;
        &lt;/dependency&gt;
    &lt;/dependencies&gt;
    &lt;build&gt;
      &lt;finalName&gt;spring-test-app&lt;/finalName&gt;
    &lt;/build&gt;
  &lt;/project&gt;

  <p>What else should I do to load all the dependencies?</p>
