I have seen the same "Could not determine installation size: zip file is empty"
error from time to time, and I think this happens because the eclipse builder
is trying to download something and the download site is not responding for
some reason.

I usually just "make build" to restart and it eventually will work.

One issue I discovered when I switched from building this as user "root" to
building as another user was problems with permissions on a /tmp/p2 directory
that is created and used.  The fix was to delete that entire directory before
running "make build" again.
