OpenJFX 14, gradle

OpenJFX 14, gradle

[Michael Zucchi]

Morning,

I'm trying to work on updating some java stuff as guix currently only 
has java12 which is  a year out of date and javafx8 which is ancient.  
Apart from openjdk 13 and 14 which is in motion I've started looking at 
openjfx 14.

But openjfx needs to be compiled with gradle 6 now - the openjfx8 
package uses ant but that is no longer an option (there's some netbeans 
ant files there but they seem non functional).  guix has no build-system 
gradle and looking at gradle I can't imagine there will ever be a 
source-bootstrapped package for it - the 6.0 distribution is 215 jar 
files, mostly external libraries, and it needs gradle to build (because 
of course it does).  I'm assuming that guix wouldn't accept using 
gradle-wrapper here which is the `supported' build mechanism for the 
openjfx project.

Partly out of curiosity and partly as a potential alternative I spent 
the weekend creating a single 1000 line gnu makefile to replace the 
 >10kloc of gradle scripts and existing makefiles.  I haven't bothered 
with javafx.web or javafx-swt but otherwise it's complete and only 
requires antlr 4.7 at build time.  It uses gnu make features 
specifically and assumes a gnu environment, but it's 3-4x faster on my 
machine (amd r9-3900x).

Another alternative could be simple build script that forgoes 
incremental and parallel compilation support for a smaller script. I can 
possibly get that down to a few dozen lines of bash if i can utilise the 
existing makefiles.

Is either approach worth pursuing or is the whole idea a lost cause?

Regards,
  Michael

Note that the ant-build-system is able to generate its own build.xml. that's going to be tough, so whatever works for you is fine, as long as everything is free software and source-bootstrapped.

Hi Michael,

I did almost the same thing but for JDKu8, You can check it https://gitlab.com/Levenson/ in a wip-davmail branch. I packaged graphics, swing, swt and friends. Unfortunatelly tests are disabled for now. I and am trying to make them work. It seems to me that even they do have tests for modules, a bundle needs to be created with all the modules first. 

I thought about makefiles, ant and build.xml, but decided to do everything in scheme for now. My plan is to make tests work, and then polish packages definition.

At least for openjfx14 the main module resources need to be inside a jar 
file otherwise they can't be found, having them on the classpath isn't 
sufficient.  For the css files for example resolving resources in 
"com/sun/javafx/scene/control/skin" takes a different code path that 
seems to enforce this.

An additional wrinkle with 14 using modular java is that the tests need 
some proxy classes built into the modules - i found the easiest way is 
just to recompile everything again with the additional sources on the 
module source path.  It doesn't take very long at least.

I've only looked at the per-module unit tests and i got them to run ok 
apart from one test which seems to be locale related (LANG=C works).  
Those all-commented-out tests are still all-commented-out in 
javafx14(!).  There seems to be a surprising amount of baggage like that 
in the repository like the netbeans stuff, which seems nonfunctional.

I just don't know enough scheme or guix and looking at the scheme source 
it looks pretty ugly when running a bunch of shell commands in 
sequence.  ant is so very painful for non-trivial builds and pretty 
useless otherwise.  make has the benefit of easily supporting parallel 
compilation which speeds it up quite a bit (at least without javafx.web 
dominating).  The bash script i have is about 240 lines so somewhat more 
compact than the makefile i have but it uses the exising javafx.media 
makefiles which cuts it down quite a bit.

Thanks for the link, that will help trying to work out how to get this 
going within the guix build system.  I also need antlr4 which i'm hoping 
wont be too hard if i remove some of the optional parts/languages.

Cheers,
  Michael
