Arch Linux User Repository

If you have installed openjfx somewhere else, you can try to set the JAVAFX_PATH environment variable to its location before launching maptool.

What package did you install? I'm using java21-openjfx which works fine. However, I am having issues building gradle7 which is needed to build java21-openjfx.

So I've been trying to get this to work as a Linux noob, I've been getting this error: /usr/lib/jvm/java-21-openjdk/lib/javafx*.jar' not found (translated from german)

As far as I understand, javafx is no longer supported by the openjdk (https://stackoverflow.com/a/38342245), which is why there is a separate package dependency for javafx that I found that was in fact installed, yet isn't recognized

How can I have the dependency essentially redirect where it checks for the package?

I just bumped the version. Do you have the same problem? Also try to clean the build directory just in case. Also try to build in a clean container/chroot.

Upgraded from gradle 7 to gradle 8, problem resolved. Thanks for your patience, and hopefully may help someone else...

How could I resolve this? I usually use the binary, but I'm eager for the new version. :)

My issue resolved itself so I've bumped up the version.

I'm having issues with version 1.14. It depends on java 20 but then they already upgraded to 21 right after. I'd rather not have to make a temporary java package for just this version. However, even using their latest commit and java 21, it won't work. I get the following error as a pop-up:

And it won't go away.

java-openjfx is on version 21 but declares it needs makedepends 'java-environment-openjdk=17'. It is also broken.

It was dropped from extra repo to AUR by @freswa, and disowned.

Until the problems get resolved, it would be best to pin the JDK/JRE/JFX requirements of this package to v17, as upstream fully supports it.

I resolved my issues by rebuilding everything (gradle7, jdk18-openjdk, jdk19-openjdk) in a clean chroot.

I've updated the dependencies but it is a bit of a pain to build now: You will need to build jdk18-openjdk, then jdk19-openjdk and finally maptool. I've also renamed the executable to MapTool to be consistent with maptool-bin.

Update: I am also having issues running maptool. With java version 17 to 20, with last stable version of the last commit from their repo, all result in a segfault, tested on multiple machines. I gotta get to the bottom of this.
