I am not sure why but I am getting error when trying to run my java file in cmd using javac MyCompiler.java. The file runs fine when I run it from Intellij. I have already added C:\Program Files\Java\jdk1.8.0_144\bin to class path.

The error I am getting: 

MyCompiler.java:4: error: package org.antlr.v4.gui does not exist

                   ^

import org.antlr.v4.runtime.misc.*;
^
.\CompilerParser.java:6: error: package org.antlr.v4.runtime.tree does not

import org.antlr.v4.runtime.tree.*;

The error seems to be ANTLR related but I am not sure how to fix it. Any help will be appreciated.

    Your `javac` call doesn't appear to have anything to include antlr jar files in the classpath. Hopefully that's enough of a hint for you to research further. – Jon Skeet Mar 21 '18 at 20:31
  • See https://github.com/antlr/antlr4/blob/master/doc/getting-started.md for an example of how to run the generated file – Ruan Mendes Mar 21 '18 at 20:39
