Configuration

• JetUML Release: JetUML-3.7.jar
• OS + version: Arch Linux (up to date)
• Java version: openjdk 22 2024-03-19
  • JavaFX version: java-17-openjfx

Additional information How I start JetUML:

java --module-path "/usr/lib/jvm/java-17-openjfx/lib/" --add-modules=javafx.controls,javafx.swing,java.desktop,java.prefs -jar /home/stk/Downloads/JetUML-3.7.jar

When I tried to install JetUML using the Arch User Repository, it won't work because it doesn't find my version of JavaFX.

==> Starting package()...
cp: cannot stat '/usr/lib/jvm/java-18-openjdk/lib/javafx*': No such file or directory
==> ERROR: A failure occurred in package().
    Aborting...
error: failed to build 'jetuml-3.4-0':

Closing because this was using an obsolete version of JetUML (3.4). Archlinux is community-contributed and no longer up to date.
