Sonar ecosystem upgrades to Java 8
With the release of SonarQube version 5.6, the entire Sonar ecosystem will drop support for Java 7. This means you won't be able to run new versions of the SonarQube server, execute an analysis, or use SonarLint with a JVM < 8.
Why? Well, its been over two years since Java 8's initial release, and a year since Oracle stopped supporting Java 7, so we figured it was time for us to stop to. Doing so allows us to simplify our development processes and begin using the spiffy new features in Java 8. Plus, performance is up to 20% better with Java 8!
Of course, we'll still support running older versions of ecosystem products, e.g. SonarQube 4.5, with Java 7, and you'll still be able to compile your project with a lower version of Java. You'll just have to bump up the JVM version to run the analysis.
