title: SonarQube 5.6 with Java Project (JDK 1.6)
body: <p>I want to configure SonarQube for my maven project which is on jdk 1.6. 
  Can I use the latest SonarQube 5.6. It say code should be complied with jdk 1.8 only.
  Is it possible to analyse code with older version of JDK with SonarQube on latest vesrion of JDK?</p>
  
  <p>My project is compiled on jdk1.6. Do I need to use scanner which supports jdk1.6 because if I uses sonar-maven-plugin - 3.1.1 it gives error :   </p>
