Minecraft Server Setup

A command-line tool to simplify the setup of a Minecraft Server. This tool helps you download the server software, configure basic settings, and generate the necessary startup scripts.

Features

• Supported Server Software: Easily download and set up various Minecraft server types:
  • Paper
  • Spigot
  • Purpur
  • Velocity (Proxy)
• Version Selection: Choose from available versions for the selected server software.
• EULA Acceptance: Prompts for Minecraft EULA acceptance.
• Customizable Setup:
  • Specify the server installation path.
  • Set the amount of RAM allocated to the server.
  • Option to enable the server GUI.
• Java Version Check: Automatically checks if a compatible Java version is installed for the chosen Minecraft version and provides guidance if not.
• Interactive Mode: If arguments are not provided, the tool will guide you through the setup process with interactive prompts.
• Progress Bar: Shows download progress for server files.

Prerequisites

• Java Development Kit (JDK): A compatible version of Java is required depending on the Minecraft version you choose. The tool will inform you if your current Java version is not suitable.
  • Minecraft 1.20.5 and newer: Java 21 or newer
  • Minecraft 1.18.x - 1.20.x: Java 17 or newer
  • Minecraft 1.17.x: Java 16 or newer
  • Minecraft 1.13.x - 1.16.x: Java 11 or newer
  • Minecraft 1.8.x - 1.12.x: Java 8 or newer

Building the Tool

This project uses Gradle. To build the executable JAR:

1. Make sure you have JDK 21 installed, as specified in the build.gradle.kts (kotlin { jvmToolchain(21) }).
2. Navigate to the project's root directory.
3. Run the Gradle build task. This will also execute the shadowJar task, creating a fat JAR.

   ./gradlew build

4. The executable JAR file, MinecraftServerSetup.jar, will be located in the build/libs/ directory.

Usage

Run the tool from your terminal using the generated JAR file.

bash
java -jar MinecraftServerSetup.jar <command> [arguments...]

Command: start

Sets up a new Minecraft Server.

Synopsis:

bash
java -jar MinecraftServerSetup.jar start [software] [version] [accept-eula] [path] [memory] [gui]

Arguments:

• software (optional): The server software to install (e.g., Paper, Spigot, Purpur, Velocity). If not provided, you'll be prompted to select one.
• version (optional): The version of the server software. If not provided, you'll be prompted to select from available versions for the chosen software.
• accept-eula (optional): Set to true to automatically accept the Minecraft EULA, or false. If not provided, you will be prompted.
• path (optional): The directory where the server should be created. If not provided, you'll be prompted. Defaults to the current directory if the input is blank.
• memory (optional): The amount of RAM (in GB) to allocate to the server. Defaults to 4 GB if not provided or if an invalid value is entered.
• gui (optional): Set to true to enable the server's GUI, or false. If not provided, you will be prompted.

Interactive Mode:

If you run java -jar MinecraftServerSetup.jar start without all the required arguments, the tool will prompt you for each necessary piece of information.

Example:

To set up a Paper server for Minecraft version 1.20.4, accept the EULA, install it in a folder named MyPaperServer, allocate 8GB of RAM, and enable the GUI:

bash
java -jar MinecraftServerSetup.jar start Paper 1.20.4 true ./MyPaperServer 8 true

If you prefer an interactive setup:

bash
java -jar MinecraftServerSetup.jar start

The tool will then ask for the server software, version, EULA confirmation, path, memory, and GUI preference one by one.

Dependencies

This project utilizes the following key libraries:

• Ktor: For making HTTP requests to download server files.
• kotlinx.serialization: For JSON parsing.
• KLI: For creating the command-line interface.
• SLF4J (Simple Logger): For logging.
