Compare Classes/Jar

[escequi]

Hello, i did some reverse on this Jar but i swear i don't remember what i changed (was on a 12 hour analysis so yea hard to remember it all and i didn't really take notes), is there any way i can compare all the classes in the jar with another jar (the unmodified version)? (bytecode)

If you check out the WIP 3x releases this feature sort-of exists:

hi, thanks for the reply; from what i understand, this only work if you haven't closed the workspace yet?

This is correct. Having a more comprehensive jar comparison scheme is planned, but not yet implemented yet.

Aight, thanks. Is there any way to export all the classes' bytecode to a .txt or something? So i can use notepad++ to compare...

Not currently, but a disassembly based text comparison strategy is what is roughly planned for the future.

3X has a WIP class-level assembler. You can go that route for now, or do basic decomp diffs until we get to adding the feature ourselves.

You can use https://github.com/sfPlayer1/Matcher for comparing JARs

IntelliJ IDEA can compare jars quite nicely too, even in the community edition.
