IntelliJ IDEA 2018.2 Help

Managing JRuby Facet in a Java Module

Basics

IntelliJ IDEA makes it possible to attach a JRuby facet to a Java module. This can be required for working with Ruby code, having resolve and code completion.

Suppose, you've created a project that contains a Java module, and you want to attach a facet to it. You must install JRuby on your computer.

By the way, if you create a module of, say, Ruby type, you may attach any available Ruby SDK.

Adding a JRuby facet

Having installed JRuby (for example, rvm install jruby), follow these steps:

  1. Open the Project Structure Dialog dialog.
  2. In this dialog, select the Facets page.
  3. Click icons general add:
    ij facet detection enabled
  4. From the pop-up menu of the possible facets that appears, choose JRuby facet:
    ij facet jruby
  5. If JRuby has been installed previously, IntelliJ IDEA recognizes it and suggests to choose a Java module to which the facet should be added:
    ij facet jruby added to module

    Select the desired module.

    After that, JRuby facet appears under the module name:

    ij facet jruby added to module1

Deleting a JRuby facet

To delete a JRuby facet, follow these steps:

  1. Open the Project Structure Dialog dialog.
  2. In this dialog, select the Facets page.
  3. Click icons general remove svg.
