title: Sonar maven plugin fails to download the JDBC driver
body: <p>I've started using the sonar maven plugin (and sonar i general). Sonar is installed on another server, and can be successfully accessed in the url <a href="http://host:8080/sonar" rel="nofollow">http://host:8080/sonar</a>. The configuration in the pom.xml is as follows:</p>
  
  <pre><code>&lt;plugin&gt;
    &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
    &lt;artifactId&gt;sonar-maven-plugin&lt;/artifactId&gt;
    &lt;version&gt;1.0-beta-2&lt;/version&gt;
    &lt;configuration&gt;
      &lt;sonar.host.url&gt;http://host:8080/sonar&lt;/sonar.host.url&gt;
    &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p><strong>Edit</strong>
  I've switch the sonar.host.url with sonarHostUrl as well, to no avail.</p>
  
  <p>(I'm still using the 1.0-beta as 2.0 require maven 3 which we haven't switched to yet)</p>
  
  <p>The sonar webapp is configured also with the right properties:</p>
  
  <pre><code>sonar.web.host: host
  sonar.web.port: 8080
  sonar.web.context: /sonar
  </code></pre>
  
  <p>When I run the sonar maven plugin (mvn sonar:sinar) here is the output. It seems that even though I've configured the location properly, the sonar still looks for the default <a href="http://localhost:9000/" rel="nofollow">http://localhost:9000/</a> installation.</p>
