There is currently no automated way I know of to do that. Someone very
familiar with ANTLR should be able to reconstruct a grammar for you though.
If you have the money you can hire me as a consultant to do it. Contact me
through www.codetransform.com. Otherwise you can start making grammars and
inspect the generated source code and figure out how to reverse engineer it.
That's a great way to learn how antlr works too!

Subject: [antlr-interest] reengineering from generated java to grammar
source
hey,
We have bumped into a serious problem. We currently have few java
class files that were generated using a grammar file with antlr
sometime in the year 2000. Unfortunately, we don't have any
remainings of the grammar file. is there a way to do some re- engineering
to generate the grammar file from the generated java
source files ?
if that's possible, I can decompile the java class files to java
source and then generate the grammar file.
Please let me know if there's a way.
regards,
-venky
