Suggestion - Add a section in Exclusions tab to add an exclusion for Class folders to stop certain classes getting turned into folders.
This would be useful of you want to prevent the main class from getting turned into a class folder.

So somehow "§" is being used, but in a weird way. For instance it is breaking chat and console messages in Spigot (color codes) with adding new unknown chars. I dont know how it is with other UTF-8 chars.

Version: latest (v1.0.9)
Java: 8

Console:

Ingame:

Something That obfuscates the name of every file amd class and bury the classes deep inside random folders with random letters and garbage and maybe an option to use Dictionaries, if you do add this, do not forget to add an option to ignore classes like a main class

Add an option to configure the class name, example: caesium_1, caesium_2 to ychusy_1, ychusy_2

that's the error.

when I use string mutation to mutate a string like "§", it will become messy code

Whilst not using the string literal mutator, I can create an obfuscated jar that runs as expected. Although, when I enable this mutator (which is essential to the software I am trying to obfuscate) I get a class format error with one of IntelliJ's UI designer classes. I created this app in IntelliJ using their java swing designer and it runs fine on java 8 with no obfuscation. Adding the "forms_rt" redist jar to the dependencies did not help.

-I am using the latest release of Caesium, and JDK 1.8.0_281.
The full error is below:

I want to obfuscate my application but i allways get this error:

message(5).txt

Getting out of memory error, please help.

Something that tells you how much precent its completed so you know when obfuscated jar would be ready, also something that shows the logs on what class it is currently obfuscating

When I ofuscated a spigot plugin, the utf-8 got bugged

Hello, could you add java 11-14 support? (without disabling reference mutation)

Personally, when I add class paths in the exclusion list, they are still obfuscated.

Example :

me.swartz.something.Main
com.google.gson. *

doesn't work.

How to use that for bungeecord plugins ?

My OS is Linux Xubuntu.
I'm getting ClassFileFormatException: Class file version does not support constant tag 15 in class file org/jboss/logging/Logger

Ability to save settings and load them.

thank you

obfuscated:

https://prnt.sc/10kq8ce

https://prnt.sc/10kq80e

without obfuscation:

java.lang.VerifyError: Verifier rejected class com.java.example.java: void com.java.example.() failed to verify:

Can you suggest the solution?

when i click mutate it doezs noting

If I run on java 11 or 14 it gives an error

how to fix

Hey,

I tried to obfuscate my program which is written in java version 17. However, I noticed that the rt.jar does not exist in higher java versions! I already tried to use the src.zip which is in the lib folder, but it doesn't work.

Could you possibly tell me which file I have to add / use so that it works?

Thanks in advance.
