How to use a custom jar?

Just 2 steps!

  1. Go to “Files”, delete everything or the files you dont want in the new setup, upload your jar

2. Choose “custom” from the Minecraft Version dropdown menu, copy the exact name of the jar file you uploaded in step 1, go to “Startup” and paste it in the jar field. Then just start your server!

* If you’re downloading/upgrading to a totally different Minecraft version or using a jar like velocity, you must first STOP your server, delete all files except “startup.sh” and then START the server with the new JAR settings. That’s because some config files & world files aren’t compatible across versions.
