Installing rwmidi library issues... only.java files no .jar might be the issue

I downloaded the rwmidi library from github and placed the unzipped folder in my library folder but processing doesnt see it. The directory structure is different from what I normally see but saw tons of posts where people are successfully using this library.... must be something I have yet to learn how to do....

The folder is structured as follows:

rwmidi [folder]
    build.xml
    doc.sh
    README
    src [folder]
        rwdoclet [folder]
            .project
            .classpath
            src [folder]
                com [folder]
                   ruinwesen [folder]
                       doclet [folder]
                           RWDoclet.java
        rwmidi [folder]
               RWMidi.java
              (11 other .java files in this folder)
