I propose to remove the obsolete NetBeans IDE files from the JavaFX
source repo. See JDK-8223375 [1]. Those files were written to run with
NetBeans 8. We sort of limped along with FX 9 using JDK 8 to browse and
navigate the sources, but it really doesn't work at all now.
I just downloaded NetBeans 12, which has added support for gradle 6.3,
to see if I could load and run JavaFX using their gradle plugin (I had
some mixed success with NetBeans 11.x).
Using JDK 14, and Netbeans' default gradle plugin, I can load the "jfx"
project, which uses build.gradle to configure the projects> I get no
warnings or errors now.
The only minor problem I had is that if I close NetBeans with the
project open, it seems to misplace the subprojects (base, graphics,
etc.) when I open it back up. I then have to close and reopen the main
'jfx' project. Then all seems happy again.
If there are no concerns, I will send a out a pull request next week to
remove the old NB project files.
