Looking for a standalone Java source code parser

[Aaron Lewis]

Hi, list,

I took a look at ANTLR first, and I did this:

wget http://www.antlr.org/download/antlr-4.2-complete.jar
wget https://raw.githubusercontent.com/antlr/grammars-v4/master/java/Java.g4

Then I created a simple Java file:
import java.io.*;

public class Foo {
    public static void main (String[] args)
    {

    }
}

It compiles with javac, so I moved to ANTLR:
%> java -jar antlr-4.2-complete.jar Foo.java
error(50): /run/shm/antlr/Foo.java:1:0: syntax error: 'import' came as
a complete surprise to me
error(50): /run/shm/antlr/Foo.java:1:11: syntax error: mismatched
input '.' expecting SEMI

Hmm, I think the g4 file I downloaded is the official one, so I must
have done something wrong.
Anyone know how to correct that?
