Being something I have put together with a java file reader and the existing minecraft code from the following file tree located through minecraft forge's mdk:
build ----> tmp ----> recompileMc ----> sources ----> net
Which displays two folders:
I have this from back in the day when Minecraft was able to be coded by decompiling it with 1300MB of data on a 32-bit computer.
Which is what I am using as an offline mod builder.
I use the above to read the files because I am not able to decompile a larger file than 1.3GB of data, and I have looked through the 1.15 .json associated with the download of the jar.
I did not see and there is not a way to look through the file and find it by searching for "obfuscation map".
So, what I have done is read is several places that the obfuscation map exists somewhere as a link to download and I am unable to locate it.
It did download additional native files with the jar as something additional that other versions that I have downloaded did not come with.
Although there is no explanation as what to do with these files or as to where the download for the obfuscation mappings is other than it being announced with the release.
the forum's information:
All future updates to Java Edition will now have their corresponding
obfuscation map be available to modders for research purposes. This
should help to speed up the time it takes for mods to be updated to new
Minecraft Wiki's information:
"Downloads to client and server obfuscation maps are now included in client.json."
I have looked in the .json file for a download link to provide me with a similar "minecraft" file and I have had no such luck.
I have similar problems with such things with other video games. Such as false advertisement or the video game being possibly editable, but I do not actually get what it is that I have purchased.
If I am not able to read what I am playing when I am the purchaser then logically I have been falsely sold a product based on comparison.
The above file that I have made being less than 3MB in file size gives me the complete ability to read the code for Minecraft.
