title: How can I read the gradle sonar runner properties from a gradle plugin?
body: <p>I am writing a custom Gradle plugin that applies the Gradle sonar runner plugin and defaults some of the parameters. I want to write a test to confirm that the properties are set correctly, but I cannot figure out how to access the data after it is set. </p>
  
  <p>I tried <code>project.getExtensions().sonarRunner.sonarProperties.getProperties()</code> and a few variants, but this either throws a null pointer or returns something other than the sonar properties. </p>
  
  <p>Is it possible to read the sonar properties after they are set? How?</p>
