Maintainer here. Sorry for the delay in answers, I am currently not using the software actively.

@zertyz I have merged @ulyssesrr's fix for the missing $JFX_ARGS after confirming it works on my machine too, so at least 3.2.3240 should install correctly.

Unfortunately it looks like that the software's author has changed the method of delivering updates, and currently I have no time to update the script to the new method. If anyone is interested in helping with this I am glad to merge their changes/add them as co-maintainer if they can be more active with updates.

I ran into the same problem as @oscar.0 . A possible fix could be to make liberica-jre-11-full-bin (AUR package) the JRE dependency instead of OpenJDK?

The program states "GanttProject requires Java Runtime with JavaFX. You are using Oracle Corporation OpenJDK 64-Bit Server VM 11.0.17+1. JavaFX is available in BellSoft Liberica or Azul Zulu Java Runtime." and exits.

The patch in previous comment assumes that latest Java is 17 and that one uses it as default Java version. I've amended it so it works regardless of default Java set and use version 17 explicitly.

Version 3.1.3100 also fails for me. A java process is launched, but there is no UI displayed. Version 3.0.3000 appears to work.

Hey guys, the program doesn’t start at all after updating everything. If I start it from the terminal I only get some messages about skipped directories, mostly heading to font directories. Do anyone have an idea what the problem is? I also tried modifying the build files as @mynacol described in his post from February.

@riazufila Try again now, I have pushed a new version.

Why when I try to open a .gan file from an existing GanttProject window, the window to Open Project (Project > Open > Open Other Project) is literally blank white? Anyone know?

Thanks @lightspot21 & @SanskritFritz for maintaining this PKGBUILD. For security reasons, would you consider switching to HTTPS in the source field, and to SHA256 for integrity check? (as MD5 and SHA1 are not considered secure algorithms anymore, and upstream does not seem to provide any official checksums anyway) Thanks :-)
