JRuby integration

IntelliJ IDEA supports JRuby to allow you to integrate Ruby code with the Java ecosystem by running Ruby on the Java Virtual Machine (JVM)

Configuring JRuby in your project is different from setting up pure Ruby projects. For more details, refer to Set up JRuby integration this topic.
