How to install antlr in idea?

Question

Java

The essence of the problem is this, I do import org.antlr.*; and gives the error "package org.antlr does not exist".
Installed plugins antlr, but the problem was not solved. Windows operating system.



What have I not done or what else needs to be installed?

Answer 1

The plugin only helps to work with the library, but it will not connect it to the project for you.

Answer 2

You have installed a plugin, that is, an extension for the IDE.
Before importing the code, you need to take this code from somewhere, for example, download it using maven.
