Build farm for OpenJFX (on ARM)

Hi Chris,

That sounds great. I currently have a zip file for the ARM build at
javafxports, in the bitbucket download section at
This is built manually, and a Jenkins CI build would be much better for
We currently do the same for the mobile builds (iOS and Android), but that
is a little more complicated as they don't build out of the box from
OpenJFX (yet), so we have a recent mirror of OpenJFX code with
mobile-specific patches (that need to go back in OpenJFX) and another
repository that contains non-JavaFX code that is required to run on mobile
devices, along with build scripts to build the SDK's. If that could be
hosted by CloudBees, it would be great.

Do you already build the JDK for ARM itself using CloudBees CI? If so, can
those be combined?

Apart from that, building is one part, the sources is another part. It will
be important to have OpenJFX as the ultimate source repository.
I am to blame myself here, as not everything that is included in the mobile
builds has been sent upstream to OpenJFX.

The main reason for this is the quality. At this moment, the sorce code in
the OpenJFX tree is of a very high quality, and I don't want to send
experimental Android/iOS stuff before we really now it is working the way
it should work. We might see the same on embedded. When Oracle was having
resources doing this, I bet there were doing lots of internal tests that
made sure only the good bits made it to OpenJFX. When the broader community
steps in, we are sort of distributing this test-system. As a consequence,
people need to have access to early or experimental builds, on the other
hand you don't want to pollute the OpenJFX repository. This would work on
e.g. bitbucket or github, by using branches etc, but unfortunately that is
not possible with OpenJFX.

Anyway, I believe having automated builds based on the code in the OpenJFX
is definitely a good thing.
