Installing custom server JARs

Please note that developer and beta builds of Bukkit and Spigot can sometimes have critical bugs that may corrupt your world, crash the server or cause other detrimental effects.

In addition, plugins for bleeding edge builds may not be compatible or may also lead to world corruption or server crashes.
It is your responsibility to ensure your server jar doesn't compromise the integrity of your map, server or server instance.

1. Acquire the server jar you wish to use.

  • 1.10.2: https://s3.amazonaws.com/Minecraft.Download/versions/1.10.2/minecraft_server.1.10.2.jar

Please rename your jar to custom_server.jar, doing so will allow Multicraft to launch the server with our optimised settings and will result in better performance.

2. Stop your server in the Multicraft control panel.

3. Upload the server jar to the jar directory in your server via FTP. If you are unfamiliar with FTP you can consult our guide on getting started with FTP here.

4. In the jar dropdown, select "default" then enter the file name of the jar in your Multicraft control panel including the .jar file extension (for example, "custom_server.jar").

5. Save your Multicraft settings.

6. Start your server.
