Does SonarQube support Java9?

The question is actually twofold:

  • Can Java9 projects be analyzed using SonarQube?
  • Can SonarQube run JVM on Java9?

Same question for Java8

TL; DR: YES !!! It supports the analysis, apparently starting July 3, 2017. (But they are desperate to hide the fact ...)

At the moment (2017-10-24, SonarQube version 6.6), SonarQube can parse Java9 code using SonarJava 4.11 or newer , but runs on Java9 JVM is not officially supported .

Java Plugin Compatibility for SonarQube

Despite the SonarJava page , specifying support for Java8 only:

Supported Versions, Framework, and Special Analysis

  • Java language versions through 8

SonarJava 4.11 release news says otherwise:

SonarSource Team is pleased to announce the release of SonarJava 4.11.

This version provides support for Java 9 projects . But what does that mean?

This means that you can parse the source files module-info.java represented by the mosaic project.

In addition, support is explicitly displayed on the same page:

  • Try-with-resources enhancements
  • Private interface methods
  • Diamond operator extension
  • JaCoCo Reports for Java9 Classes
