title: Github.io could not find artifact:
body: <p>Seems like I can't find an artifact in github.io. from a maven project.</p>
  
  <pre><code>Could not resolve dependencies for project 
  org.Project_Name: Could not find artifact 
  es.Artifact_Name in maven-nuxeo 
  (https://maven.nuxeo.org/nexus/content/groups/public/)
  </code></pre>
  
  <p>This artifact is in the respository:</p>
  
  <pre><code>http://company_name.github.io/.../maven
  </code></pre>
  
  <p>That's included in the pom.xml of the module, and I can see this artifact on</p>
  
  <pre><code>github.com/../maven
  </code></pre>
  
  <p>But anyway,copying the urls from the error I can't see the file from github.io. The URL is:</p>
  
  <pre><code>github.io/.../maven/../Artifact_Name
  </code></pre>
  
  <p>Also I noticed that the url from github.com includes the branch like:</p>
  
  <pre><code>github.com/../maven/tree/branchname/maven/..
  </code></pre>
  
  <p>while github.io is written without specifying the branch, like:</p>
  
  <pre><code>http://company_name.github.io/../maven/maven/..
  </code></pre>
  
  <p>In case it helps, the last instruction displayed in console from maven is:</p>
  
  <pre><code>Downloading from github-company-maven-repos: http://company_name.github.io/maven/maven/es/org/repo/repo-apirest/1.0.8/Artifact_Name-1.0.8.jar
  Downloading from repo-maven-apache-org: https://repo.maven.apache.org/maven2/es/org/repo/repo-apirest/1.0.8/Artifact_Name-1.0.8.jar
  </code></pre>
  
  <p>The question: Is there any error with the urls, or any recent change in github.io that makes any of the urls not functional anymore? I am already aware of the recent change that there can't be capital letters in the urls.</p>
