Answer 1

a) Decompiler ( https://www.jetbrains.com/decompiler/). Delete.
b) Find the code on github or somewhere else to download, delete, compile.
But it’s better not to do this, because you have to figure out what to delete and what not. And it’s not bad to break the library in an unexpected place =)
