Rebuild .jar library from source files

Question

Hey guys I have a simple question.

I downloaded and used the jml library to make my own messenger. This all worked until I decided to make an Android version of it. It appeared that I had to change 2 lines in two class files and patch 1 file in the source. So I downloaded the source and did this.

Now I need to make a .jar file out of the source again so I can add it to my project as an "external jar".

Screen of the source folder:

I hope I could make my question clear.

Thanks in advance,
