Question

I don’t know how to add the this into my existing project.

The only thing I learned so far was adding jar files, not those types of folders. How would I add the source to my project? Are they packages?

Steps I’ve done:

1. Download
2. Extract into a separate folder

I think I might be over thinking it.

If I interpret the download link right, you are downloading the sources of a lib.

If you are not already using that library, you should download this instead and add it to the project’s build path. Copy it to your folder, where you have your other libs placed and add it via right click menu Build Path *–>* Add to Build Path. Afterwards you can use the classes from that library.

If you already have that lib in your project, I guess you want to attach the sources to the lib. Therefore you need to go into your project’s build path and edit the jar, and configure there, where the zip file (which does not need to be extracted) with the sources is. There is a detailed description for linking sources to jar files in the eclipse documentation.

For further details on build path configuration you could read in the eclipse documentation.
