Unrelated but these source.dir and source.absolute.dir appear unused. Then you
can also not pass in SOURCE_DIR from gyp, and it's clear that this doesn't do
any compilation

[cjhopman, 2013/04/09 15:49:47]

source.absolute.dir is passed to the apkbuilder task below. I've no idea what it
uses that for (i.e. it shouldn't package anything in there), at some point I
might dig into that task's source to figure out what it's doing.

   <property name="source.absolute.dir" location="${source.dir}" />
