What is minimal sample Gradle project for ANTLR4 (with antlr plugin)?

Question

I have created new Gradle project, added

apply plugin: \'antlr\'

and

dependencies {
    antlr \"org.antlr:antlr4:4.5.3\"


        

Answer 1

The Gradle sample noted by @Mark Vieira only got me halfway there. I found that I had to specify the package in the header of my ANTLR grammar file in order for everything to be seen in both directions (generated code able to access hand-written code and vice-versa).

grammar MyGrammar;

@header {
    package com.mypackage;
}

Prior to switching to Gradle, I had been using the ANTLR plugin in IntelliJ, which filled in the package for me. Upon switching to Gradle, the package went away, which caused problems.
