 ANTLR is really two things: a tool that translates your grammar to a parser/lexer in Java (or other target language) and the runtime needed by the generated parsers/lexers. Even if you are using the ANTLR Intellij plug-in or ANTLRWorks to run the ANTLR tool, the generated code will still need the runtime library. 
 
-The first thing you should do is probably download and install a development tool plug-in. Even if you only use such tools for editing, they are great. Then, follow the instructions below to get the runtime environment available to your system to run generated parsers/lexers.  In what follows, I talk about antlr-4.10-complete.jar, which has the tool and the runtime and any other support libraries (e.g., ANTLR v4 is written in v3).
