Trouble with setting up ANTLR

[Dominick Marciano]

I recently downloaded the antlr-4.1-complete.jar files and I'm using the "The Definitive ANTLR4 Reference" book to learn it (as I have never used ANTLR before).  However I ran into an error message and I can't figure out how to fix it.  In section 1.2 "Executing ANTLR and Testing Recognizers" I was trying to use the runtime library called "TestRig" but when I tried to execute "java org.antlr.v4.runtime.misc.TestRig" at the command prompt I get the following error message "Error: Could not find or load main class org.antlr.v4.Tool"

The following are the directories that I'm using right now:

Java:           C:\Program Files (x86)\Java\jre7\bin

ANTLR Jar:  C:\Users\Dominick\Desktop\Programming\ANTLR\Binaries

Hello.g4:      C:\Users\Dominick\Desktop\Programming\Grammars\Hello

I've tried executing the command while the current directory was the "Binaries" and "Hello" directories but I get the same error message.  I also set up a shortcut to the command prompt to run a script when it starts to set up some aliases, specifically:

DOSKEY grammars=cd C:\Users\Dominick\Desktop\Programming\ANTLR\Grammars\$1

DOSKEY antlr=java -jar C:\Users\Dominick\Desktop\Programming\ANTLR\Binaries\antlr-4.1-complete.jar $1

I suspect the problem is related to the CLASSPATH and/or PATH variables, but I'm not complete sure how to set these up.  Under Environment Variables, the following are present:

User Variables

CLASSPATH: 

C:\Program Files (x86)\Java\jre7\bin\ (I manually added this)

PATH:            

C:\Program Files (x86)\Microsoft Visual Studio 2008 SDK\VisualStudioIntegration\Tools\Sandcastle\ProductionTools\

C:\Program Files (x86)\Java\jre7\bin\ (I manually added this)

System Variables

CLASSPATH: 

C:\Program Files (x86)\Java\jre7\bin\ (I manually added this)

Path:

C:\Program Files (x86)\Intel\iCLS Client\;

C:\Program Files\Intel\iCLS Client\;

%SystemRoot%\system32;

%SystemRoot%;

%SystemRoot%\System32\Wbem;

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;

C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;

C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;

C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;

C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT

;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x86;

C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64;

C:\Program Files\Microsoft\Web Platform Installer\;

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;

C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;

C:\Program Files (x86)\Microsoft SDKs\TypeScript\;

C:\PROGRA~1\CONDUS~1\DISKEE~1\;

C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\

C:\Program Files (x86)\Java\jre7\bin\ (I manually added this)

Everything else seems to working so far.  For example, if I type the following two commands:

grammars Hello

antlr Hello.g4

The current directory will change to C:\Users\Dominick\Desktop\Programming\ANTLR\Grammars\Hello (where I have my Hello test grammar) and all the files it's suppose to create are created (e.g. Hello.tokens, HelloLexer.java, HelloListener.java, etc.).  I just can't get the "TestRig" tool to run.  

Thanks in advanced for any help with this.  I really don't want to continue with the book until I can get this working since I assume I'm going to need to use this later on.

To execute TestRig, you’re going to need to have the ANTLR jar file in your classpath.  You only have Java itself in your classpath.
