If you just want to experiment with what it can do, download the
AntlrWorks program and run it.
http://antlr.org/works
You can use it to help write your grammar (.g) files, then preview how
they work, and finally use it to generate the .java files that you can
copy into your project.
There are two parts of ANTLR. The first part is the generator, and the
second part is the runtime. The "generator" part is a Java application
that takes .g files and generates .java files. That part is included in
AntlrWorks, and you do not need the JAR for it anywhere, not after
you've done the .g->.java step. The only time you need that JAR is if
you want Maven to automatically take your .g files and make .java files
for you as part of your compiling process, but when starting out just
use AntlrWorks to do it manually.
The "runtime" JAR is what you need for your project. (There are also
other versions of it for other programming languages.) You can download
the runtime from this page, under "Runtime Libraries"
http://antlr.org/download.html
Maven is not required. ANT is not required. But you *could* use either
one to automate certain steps, if you really want to.
