Help with understanding how this program work

[iGabyTM]

I have tried to deobfuscate a jar file for testing and I can't figure out how to add the libraries used. This is my config:

input: in.jar
output: out.jar
path:
  - D:/Program Files/Java/jdk8u242-b08-jre/lib/rt.jar
  - D:/Projects/MinecraftServers/test/server.jar
libraries:
  - D:/Projects/MinecraftServers/test/server.jar
transformers:
  - normalizer.SourceFileClassNormalizer
  - normalizer.MethodNormalizer: {}

Could not locate a class file.
Have you added the necessary files to the -path argument?
The error was:
com.javadeobfuscator.deobfuscator.exceptions.NoClassInPathException: org/bukkit/event/Listener

Also, I noticed that MethodNormalizer require a value named mapping-file, how do I generate one?

Taking a quick peek at the AbtractNormalizer and MethodNormalizer classes, it doesn't look like the mapping-file field is actually used anywhere.

Regarding the NoClassInPathException, make sure you're using a server jar which contains the Bukkit API (spigot, paperspigot, craftbukkit, etc.).

Your configuration looks correct to me, just make sure that the server.jar contains the class that you are looking for.
