Way to Run Jar Installer?

Is there a way to add a game to Heroic where the installation file is a .jar?

I am trying to manual add Forge (Magic the Gathering Engine) https://github.com/Card-Forge/forge It has a .jar for an installer and isn't the advantage of Java is that you write once run everywhere?

you would set your jre executable as your target and add your .jar as launch options

So I tried to make a new LInux game where I run java with the proper parameters. It runs and closes very quickly. No files are adjusted in linux that I can tell. I couldn't actually set/select the java files with the Heroic Browser. I just typed the path in. Here are screenshots of the settings. https://i.imgur.com/e7kzVa5.png https://i.imgur.com/EPlww4b.png

How did you install Heroic?

That's the Flatpak version (judging by the image path)
Flatpak can't see your system Java (and there's not really a way to make that work)

You could download the java jdk and stick it in a folder that the flatpak does have access to, https://jdk.java.net/

I am using Mint Linux. Yes it is the flakpak version. There is no System Pack in the Software Manager.

Could you give me an example of a folder/location that the heroic-flatpak would have access to?

Looks like heroic has access to ~/Games/Heroic~/Games/Heroic by default so you could put it in there with no issue.

Otherwise, you could put it anywhere in your home folder and use something like flatseal (another flatpak) to give heroic perms to access that folder.
