@kruzah, Thank you, setting the default java version to 19 fixed everything. java-openjfx was automatically installed as a dependency. No need to keep java 8 around and therefore no more python2 required.

It's a bit of a pitfall that you can only set the default java version to a fixed version and not make the most recent the default automatically. If you barely use java and don't care about it, you might get stuck on a years old version unwittingly and some day it will cause problems.

Minion does not require Java 8, and you should probably not install it if it requires Python 2. The package is compatible with all of the other JVMs that are currently supported by Arch Linux, and I would recommend installing those instead and uninstalling Java 8 from your system unless you have a package installed that explicitly requires Java 8.

To use the latest version of OpenJDK, install using pacman -S java-openjfx jre-openjdk. You then need to switch to it using archlinux-java set <version>. Per the time of writing, the latest version is Java 19, so you'd have to run archlinux-java set java-19-openjdk. If you are unsure, you can run archlinux-java status to see the list of Java versions you have installed on your system.

You need to ensure that you have a version of OpenJFX installed that matches the version of Java you are using. Check this with archlinux-java status. If you are using Java 19, you need to install java-openjfx. If you are using Java 17, you need to install java17-openjfx. If you are using Java 11, you need to install java11-openjfx.

This should fix all the issues mentioned below, including "main class not found" and the unnecessary dependency on Python 2.

I tried the workaround with changing the dependency of miniongg from java-openjfx to java8-openjfx and then removing python2 from the dependencies of java8-openjfx but then java8-openjfx fails to build because python2 is required.

python2 is not a dependency of miniongg and I don't have it installed. I tried uninstalling and removing java-openjfx from miniongg's dependencies and still get the same error: "Main class gg.minion.Minion could not be found or loaded"

Today there was a update from Java8-openifx, but it will bring back python 2 and some other new packages i don´t need. I set it on my ignore list.

I can not start Minongg anymore: Error: Main class gg.minion.Minion could not be found or loaded

I think it has to do with the dependencies: java8-openjfx and Python2 I find out if i delete the dependencie "Python2" from the pkgbuild of "java8-openjfx" it works as it should

I have the two dependencies installed as per the pacman-gui but I am still unable to start miniongg. Here is what my terminal spits out:

[dave@ArcoLinuxB Desktop]$ miniongg

Error occurred during initialization of boot layer

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

Any ideas what extra packages I need to install? Thanks.

Error: Could not find or load main class gg.minion.Minion

I could just be dumb. Unsure of what to do, though.

@kruzah Nice, thank you!
