MinecraftPython

This tutorial works with Minecraft Java Edition 1.16.5

Install the spigot server:

• Createa an empty directory on the server machine named MinecraftPythonServer in the home directory, then navigate the the directory by using:

cd ~/MinecraftPythonServer

• Download the spigot server from GetBukkit: https://getbukkit.org/download/spigot. Downlaod the right version of your choice and put the jar file in the above created folder.
• Extract and install the server with the downloaded jar file: spigot-1.16.5.jar by using the command:

java -Xms1024M -Xmx1024M -jar ./spigot-1.16.5.jar nogui

• The command above should generate an error for the first time of installation due to not accepting the user agreement EULA.
• Go to the installation directory and find the eula.txt file. Change the accept=false property from false to true. Save and exit.
• Enable firewall on the server's port:

sudo ufw allow 25565

• Re-run the server startup command:

java -Xms1024M -Xmx1024M -jar ./spigot-1.16.5.jar nogui

Create a World on Server:

• Once the server is booted up, create a world by following the steps below.
• Open Minecraft game --> Play (ensure you have a paid account) --> Multiplayer --> Add Server --> Name: AdalMinecraftPython, IP: localhost:25565 --> done.
• Double click into the server to ensure everything is running okay, then exit.
• Stop the server by type the stop command on the commandline.

• Download the plugin from https://www.spigotmc.org/resources/raspberryjuice.22724/.
• Save the file to the plugins folder int the installation direcotry: ~/MinecraftPythonServer/plugins/raspberryjuice-1.12.1.jar
• Re-start the server. This time the raspberryjuice plugin will be found and applied.

java -Xms1024M -Xmx1024M -jar ./spigot-1.16.5.jar nogui
