Porting Eclipse 4.11

[Jonathan Chen]

Hi,

I'm not sure whether there's anyone on this list anymore, but if
there's anyone able to help I'd appreciate it.

I'm attempting to port the upcoming Eclipse 4.11 (code-named 2019-3)
to FreeBSD. My efforts are available on:
  https://github.com/daemonblade/freebsd-eclipse

I've brought over the most of the patches from the 4.6 port, and have
made most of the obvious changes. Currently the port builds 220/485
modules. It currently fails on:
[INFO] Building org.eclipse.e4.ui.swt.gtk 1.0.500-SNAPSHOT            [221/485]

I can't seem to determine why the module isn't recognising the
completed org.eclipse.swt.gtk.freebsd.amd64 module which contains the
built classes. It's bound to some simple config line I've missed
somewhere - any help appreciated.

Cheers.
