SonarQube and SonarQube plugins rely on “Language Pack plugins” for translations. By default Bitnami package for SonarQube™ embeds the English Pack.
In order to translate your SonarQube application, you need to install the proper “Language package” as you would any other plugin. Refer the Plugins instructions for more information on this.
You can find more information about the SonarQube Internationalization project at SonarQube’s official Internationalization documentation.
