title: m2eclipse cannot update index from central repo
body: <p>I have just downloaded and installed M2Eclipse, but it fails to update the index of the central repo.
  At the same time, Maven itself is able to download artifacts from the repo (via command line).</p>
  
  <p>I had the <code>settings.xml</code> file in <code>maven/conf</code>, and I copied it to <code>.m2/</code> directory, but it didn't help.</p>
  
  <p>I have proxy, but proxy settings are given in <code>settings.xml</code> - commands from command line work fine, but not in Eclipse. In Eclipse it gives me this: </p>
  
  <pre><code>Unable to update index for central|http://repo1.maven.org/maven2
  </code></pre>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>This is what I get when I try to create a new Maven Project:</p>
  
  <pre><code>Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE from any of the configured repositories.
  Could not resolve artifact
