JavaFX Maven Plugin

Hey guys,

Is there any more news on the open sourcing of the packaging tools? It's
been a "few days away" since October 27.

I have made some good progress with the JavaFX Maven Plugin. It now
supports a lot of stuff Maven users would expect and could potentially
reduce the barrier to entry for a lot of people to using JavaFX, especially
Maven users (i.e. the bulk of the JEE community). I've written a blog post
showcasing some of the more useful features here:

I have also made in-roads into getting it so that WiX can be downloaded
automatically for users when needed, instead of the current, very non-Maven
need to manually install it. I have permission (or at least recognition and
no objections) from the WiX devs to put the zip of Wix in the Maven repo.
I'm half way through the motions of making this happen.

Unfortunately the JFX native bundler code is totally hard coded for a lot
of things it shouldn't be and I am going to have to build my own so I can
use the downloaded WiX (the jfx packager assumes it is on the system path).
I think using Velocity templates I can make a more
powerful/customisable/extensible native bundler anyway, so rewriting this
was already on the cards and it doesn't look overly complicated.

What I'd really like to not have to rewrite are the native launcher
executables that get bundled into the installers (i.e. the "exe" on
windows). I can rip these out of the Java bundle for now to do my
development but I won't be able to release my improved bundler until these
bits are open sourced, giving me the legal all clear to include them in my

Any chance I could get an actual timeframe on when the packaging tools are
to be open sourced?

I'm doing my best to contribute what I personally think is vitally
important for JavaFX. In general I'm accepting of the fact that what I'm
doing is not something Oracle sees as overly important and I'm on my own
(it's been quite a liberating attitude to take to be honest). Open Sourcing
the packaging tools however, was something you said you were going to do
anyway and it would save me having to write a whole new native launcher for
each platform.
