sonarqube analysis requires authentication when permission is anyone
<p>sonarqube 5.5 
several Java projects, all have permission set to anyone can execute analysis.
use mvn sonar:sonar to run analysis 
Other projects work fine without error.
One project was found to not have the permission set. It was giving:</p>

<blockquote>
  <p>Not authorized. Analyzing this project requires to be authenticated.
  Please provide the values of the properties sonar.login and
  sonar.password.</p>
</blockquote>

<p>Setting the permission does not fix it.  This project continues to give this error.</p>

<p>Steps taken:</p>

<ul>
<li><p>Permission is being set on the Project Permissions page, adding Anyone group to EXECUTE ANALYSIS permission.  Users 0, groups 1</p></li>
<li><p>toggle permission off then on again.</p></li>
<li>restart server.</li>
<li>remove local sonar/cache </li>
</ul>

<p>There are two projects with the same name but different keys.  QA version and Release.</p>

<p>Not sure what to try next.</p>
