when studying the source code, you need to associate the source code, debug and code, and in some places you may want to take notes and add comments.
but the jar form of the associated source code package cannot be edited.
so is there any simple and effective way to make it editable?

I want source code editable .
so far I know that you can edit the source code by decompressing the source package and associating the decompressed folder. But this is too troublesome!
every source jar package is like this. I will be exhausted to death.
