Yes, you certainly don't want them under version control - you said yourself "ship" which is the built source tar ball, not your repository ;). >> Your package won't work without them ... > :-) yes, I know this (> 20 years of experience with Java, slightly less with > R). > >>> In the meantime I found the following suggestion >>> http://romainfrancois.blog.free.fr/index.php?post/2009/03/26/Hello-Java-World >>> which is close to what I was thinking of. >>> >> Well, that's in essence what has been suggested.

The preferred setup is very individual (e.g. I avoid ant in my Java packages), so I don't think it's R's place to step in at that stage. I did consider adding some primitives, but given the individuality I just opted for conventions (like inst/java as a distribution place).
