Why sonar-maven-plugin-3.0.1.jar cannot be found when executing sonar:sonar?
<p>We are currently including (reactivating) sonar in our continuous build process and we are experiencing some issues.
In order to focus only on sonar I tried to make it work on an "HelloWorld" project but still without any success.</p>

<p>One jar (sonar-maven-plugin-3.0.1.jar) seems to be missing from repo1 and repo2. I've browse those locations and only pom can be found here.</p>

<p>Neither it can be found on the following url:</p>

<ul>
<li>[<a href="http://www.java2s.com/Code/Jar/s/sonar.htm][1]" rel="nofollow">http://www.java2s.com/Code/Jar/s/sonar.htm][1]</a></li>
<li>[<a href="http://mvnrepository.com/artifact/org.codehaus.sonar/sonar-maven-plugin/3.0.1][2]" rel="nofollow">http://mvnrepository.com/artifact/org.codehaus.sonar/sonar-maven-plugin/3.0.1][2]</a></li>
</ul>

<p>So far I didn't found any archived version of this jar.</p>

<p>At this point any help is warmly welcome.</p>

<p>Here is my repo (only the org\codehaus\mojo part):</p>
