Sonar maven plugin fails to download the JDBC driver

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 http://host:8080/sonar. The configuration in the pom.xml is as follows:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>sonar-maven-plugin</artifactId>
  <version>1.0-beta-2</version>
  <configuration>
    <sonar.host.url>http://host:8080/sonar</sonar.host.url>
  </configuration>
</plugin>

Edit I've switch the sonar.host.url with sonarHostUrl as well, to no avail.

(I'm still using the 1.0-beta as 2.0 require maven 3 which we haven't switched to yet)

The sonar webapp is configured also with the right properties:

sonar.web.host: host
sonar.web.port: 8080
sonar.web.context: /sonar

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 http://localhost:9000/ installation.

Any idea how to solve this?

Well, my configuration was wrong. You shouldn't have any <configuration> inside the plugin definition, but rather a <properties> block with the Sonar properties:

<properties>
  <sonar.host.url>http://host:8080/sonar</sonar.host.url>
  <sonar.jdbc.url>jdbc:mysql://host:3306/sonar</sonar.jdbc.url>
  <sonar.jdbc.username>sonardb</sonar.jdbc.username>
  <sonar.jdbc.password>sonardbpassword</sonar.jdbc.password>
  <sonar.jdbc.driver>com.mysql.jdbc.Driver</sonar.jdbc.driver>
</properties>

Thanks to Freddy Mallet for pointing it out.

add in maven settings.xml the next code:

<profile>
        <id>sonar</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <!-- EXAMPLE FOR MYSQL -->
               <sonar.jdbc.url>jdbc:mysql://localhost:3306/sonar</sonar.jdbc.url>
                <sonar.jdbc.driver>com.mysql.jdbc.Driver</sonar.jdbc.driver>
            <sonar.jdbc.username>root</sonar.jdbc.username>
            <sonar.jdbc.password>1234</sonar.jdbc.password>

            <!-- optional URL to server. Default value is http://localhost:9000 -->
            <sonar.host.url>
              http://localhost:9000
            </sonar.host.url>
        </properties>
    </profile>
