Hi
Using ANTLR 3.1, I am rebuilding ANTLR from the sources and got this
exception
[myjavac] C:\Program Files\ANTLR\antlr-3.1\codegen\ANTLRLexer.java:61:
duplicate class: org.antlr.
tool.ANTLRLexer
[myjavac] public class ANTLRLexer extends antlr.CharScanner implements
ANTLRTokenTypes, TokenStrea
m
Any idea where the problem could be? or how to fix this?
TIA
