In view of the fact that the JRuby is in our database as a program to support or convert various file extensions, you will find here a JRuby download link. Get the software from the JRuby developer website. Before you will download the program, make sure that you not have application JRuby on your device installed yet - this will allow you to save some space on your disk.
We do not store any files with the setup of the JRuby on our server but help to find the most reliable source from where you can download the application from. By clicking on the button "More info about JRuby" you should be directed to the official website of the JRuby developer where you can download the application.
