Listing OptionalDependencies in manifest.json causes a Java.lang.IllegalArgumentException

[mixels]

I recently updated my project that uses this template to use LuckPerms as an optional dependency. So I added LuckPerms to my dependencies via build.gradle, updated manifest.json, and updated my project to use it if it's available. Then I copied LuckPerms.jar to the Hytale UserData\mods folder, updated gradle.properties to set load_uder_mods=true, and hit the Debug button. The below exception appears on startup.

manifest.json

    "OptionalDependencies": {
        "LuckPerms:LuckPerms": "*"
    },

This appears to be a problem with the way that template task to run the server is configured. But I don't fully understand the run server task, so I'm a bit out of my depth here. Any ideas?
