nukkit-1.0-snapshot.jar

How on earth do I use custom worlds??? I know Nukkit uses java edition worlds so I copy and pasted all the files from the world I wanted into the worlds/world/ folder and replaced the old files yet when I log onto the server its opens the old world yet there doesn't seem to be any place that...

How on earth do I get a resource pack to load on a world??? do I create a folder named "resource_packs" in the /worlds/world folder and plop it in or dose it have to be a resources.zip file because nukkit runs java worlds, and dose it have to be a bedrock edition resource pack or a java edition one

When I try to start my server the console says this: (i hid my ip address) 10:51:07 [INFO ] Loading nukkit.yml ... Exception in thread "Thread-1" java.lang.ExceptionInInitializerError at cn.nukkit.console.NukkitConsole.runCommand(NukkitConsole.java:29) at...
