I am currently writing a java library that I intend to release under MIT license.

Right now I have drawn on another MIT license library.

I would like to only use a couple source files/classes from the other library in my library. I would like to just embed those source file directly in my library and modify them as I see fit to meet my needs.

Is this compliant with MIT license? What do I need to add to my GitHub page when I publish it, in regards to the portions of the other library that I embedded in my own?


To quote the MIT License:

So - you can redistribute modified versions of specific classes from an MIT-licensed project. You'll have to keep the original copyright and license for them, though.

An acceptable approach could be to have such a paragraph in your license (or readme) file:

Classes under the XYZ package were taken from project ABC, Copyright 1999 Original Author. These classes are licensed under the MIT license. See XYZ-LICENSE.md for additional details.
