title: maven plugin sonarqube doesn't resolve it's dependencies
body: <p>When I try to run the mvn sonar:sonar target maven are unable to run sonar, here is the relevant part of the mvn output:</p>
  
  <pre><code>[INFO] Execute: org.codehaus.sonar:sonar-maven-plugin:3.6:sonar
  [WARNING] While downloading javax.xml:jaxrpc:1.1
    This artifact has been relocated to javax.xml:jaxrpc-api:1.1.

  [INFO] Can not execute Sonar
  
  Embedded error: Unable to load the mojo 'org.codehaus.sonar:sonar-maven-plugin:3.6:sonar' in the plugin 'org.codehaus.sonar:sonar-maven-plugin'. A required class is missing: Lorg/apache/maven/shared/dependency/tree/DependencyTreeBuilder;
  </code></pre>
  
  <p>org.apache.maven.shared.dependency.tree.DependencyTreeBuilder</p>
  
  <p>It seems like maven doesn't download the required dependency for some reason.</p>
  
  <p>I have a local nexus configured that contains the jar, but i get the same result regardless if I have that profile active in my settings.xml or not.</p>
  
  <p>How should I configure maven in order for it to try to download the dependency?</p>
