Arch Linux User Repository

Hey alba4k, which openjfx and java packages are you using? If I know exactly what packages you are using, I could try it myself and see if I run into the same issue.

Also, the launch script you pasted in your comment is outdated, it had been suggested in the past because some openjfx packages installed javafx in a separate directory, but now most openjfx packages seem to install it in the openjdk directory. Again, knowing exactly which package you're using could help.

Otherwise, I haven't run into any issues using jdk21-openjdk and java21-openjfx-bin (with java-21-openjdk set as the default environment), so you could always try those packages.

EDIT : Also just to be sure, since your initial error message suggest that java isn't finding javafx, try and see if your openjfx package is the same major version as your default java environment. I don't know exactly how java works to find the javafx modules, but it's worth a try.

Hey, having some issues here. Initially:

java.lang.module.FindException: Module javafx.base not found

then, after changing the default archlinux java environnment and the launch script to

#!/bin/sh

#JV="$(javac -version | sed -e "s,.* ,,")"
#hard-check against openjdk-17
JV=24

export PATH="/usr/lib/jvm/java-${JV}-openjdk/bin/:$PATH"

# javafx is installed to 'java-xx-openjfx', not 'java-xx-openjdk'
exec java --module-path /usr/lib/jvm/java-${JV}-openjfx/lib/javafx.base.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.controls.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.graphics.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.swing.jar --add-modules javafx.base,javafx.controls,javafx.graphics,javafx.swing -jar /usr/share/java/mcaselector.jar "$@"

this:

error: missing mode

Had to edit the launcher script in '/usr/bin/mcaselector' as follows to get it working.

Essentially, the paths for JavaFX are wrong, the AUR packages installs it to 'java-xx-openjfx'.

#!/bin/sh

#JV="$(javac -version | sed -e "s,.* ,,")"
#hard-check against openjdk-17
JV=17

export PATH="/usr/lib/jvm/java-${JV}-openjdk/bin/:$PATH"

# javafx is installed to 'java-xx-openjfx', not 'java-xx-openjdk'
exec java --module-path /usr/lib/jvm/java-${JV}-openjfx/lib/javafx.base.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.controls.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.graphics.jar:/usr/lib/jvm/java-${JV}-openjfx/lib/javafx.swing.jar --add-modules javafx.base,javafx.controls,javafx.graphics,javafx.swing -jar /usr/share/java/mcaselector.jar "$@"

Any ideas on how to fix this? It looks like an option suggested by another user was implemented to the script but not recognized by the program?

Unrecognized option: --module-path
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Edit:
Nevermind, I had to change the default java environment to a never version.

I get Module javafx.base not found. Turns out that the dependency java-openjfx will install 19.u11-1.

sudo pacman -S java17-openjfx && sudo pacman -Rsn java-openjfx

will resolve this.

Please replace the jre-openjdk dependency with java-runtime-openjdk so that we can choose which version to use.

Small suggestion for the mcaselector launcher script: Add exec to the beginning of the last line, so that the Java process replaces the shell process, instead of the shell staying around not doing anything :)

mattsturgeon, I had same problem, turned out there is no javafx jars in /usr/lib/jvm/default/lib, so I reinstalled java-openjfx.

I get Module javafx.base not found

Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.base not found

I see that java-openjfx is a dependency, so I'm not sure what the problem is.

EDIT: archlinux-java status prints:

Available Java environments:
  java-11-openjdk
  java-17-openjdk (default)
  java-8-j9
  java-8-openjdk

Launcher script suggestion: add exec to the last line, i.e. exec java --module-path … – the launcher script doesn’t need to stay around, waiting for Java to exit.
