Java – error: unable to find or load the main class test

I'm currently teaching myself ANTLR. When I finished the book "the defined ANTLR reference", I encountered a problem I'm doing the first example, creating a syntax file, getting my lexer and parser java files, and creating the following Java programs to test it:

import org.antlr.runtime.*;

public class Test 
{
    public static void main(String[] args) throws Exception
    {
        ANTLRInputStream input = new ANTLRInputStream(system.in);

        TLexer lexer = new TLexer(input);

        CommonTokenStream tokens = new CommonTokenStream(lexer);

        TParser parser = new TParser(tokens);

        parser.r();
    }
}

Then I use the command line to compile which works normally, and then I try to run the Java class, which fails. The whole command line is as follows:

I've seen a lot of solutions, and none seems to suit me The following are good:

>JDK and JRE are completely up to date > path set

Solution

Add current location to classpath:

java -cp C:\antlr-3.4.jar;. Test
