title: How to use Sonatype Nexus Repository Groups with Github raw repositories?
body: <p>How can I tell Nexus to download the artifacts from a raw github maven repository when the Proxy Repository in Nexus is in a <strong>Repository Group</strong>?</p>
  
  <p>Background: In our parent-pom we use a catch all mirror, so we don't have to configure each and every repository to the poms. This works flawless and is also common practice - example:</p>
  
  <pre><code>&lt;mirrors&gt;
      &lt;mirror&gt;
          &lt;id&gt;provided&lt;/id&gt;
          &lt;url&gt;http://nexus.host/content/groups/provided&lt;/url&gt;
          &lt;mirrorOf&gt;*&lt;/mirrorOf&gt;
      &lt;/mirror&gt;
  &lt;/mirrors&gt;
  </code></pre>
  
  <p>But when using a raw github repository this dosn't works. How can I configure Nexus to do this?</p>
  
  <p>Note: I already  read "<a href="https://stackoverflow.com/questions/17991752/how-to-add-github-raw-repositories-to-sonatype-nexus-as-proxy-repository">How to add Github raw repositories to Sonatype Nexus as Proxy repository?</a>", but this doesn't tells you how it would run with Repository Groups.</p>
  
  <p>Update: In a manual post step I created the nexus index files with the <a href="https://docs.sonatype.org/display/M2ECLIPSE/Nexus+Indexer" rel="nofollow noreferrer">nexus-indexer-3.0.4-cli.jar</a>, and commited/pushed them to github. Now nexus shows me in the "Browse Index" tab the files in the Proxy Repository, but the problem remains. Clients can not download the artifacts from Nexus.</p>
