I really like having a jar with the sources so I can jump to the code.  
However, I can’t just get it done, and the last one on maven that has sources is really outdated.

Here more about it:

There is a link on this page:

And links to this:

I have modified Processing in the past to make it “portable”.

I finally got it:

In `processing/core/build.xml`:  
Change the last target to:

```auto
<target name="build" depends="compile" description="Build core library">
    <jar basedir="bin" destfile="library/core.jar"> 
    </jar>
    <jar basedir="bin" destfile="library/core-sources.jar"> 
      <fileset dir="src" includes="**/*.java"/>
    </jar>
  </target>

```
