A template for your paper plugins written in Kotlin using Gradle Build Tool

Paper Kotlin Template

A template for basic Paper plugins written in Kotlin, using Gradle. Simply change out my information for yours, and you're good to go!

Features:

• Paperweight userdev plugin - Get the latest Paper API features, plus access to Minecraft NMS.
• run-task plugin - Run a test server with your plugin, easily right from your IntelliJ IDE
• plugin-yml bukkit plugin - Bring your plugin.yml into your build file
• libs.toml pre-setup - Organise your dependencies into your libs.toml
• GitHub workflows - to check your code from GitHub
• .gitignore - to make sure only the important stuff's being published

Setup

1. Clone the repository
2. Delete the .git folder to reset the git history
3. Refactor the plugin name & package id in the file strucutre
4. Update information in the build.gradle.kts
5. Run the build, or the run configuration to test the plugin all works
6. Hit the ground running!

Versions

I will try to keep everything up to date, though do check, and feel free to pr/update. Currently on:

Kotlin: 1.9.22

Minecraft: 1.20.4-R0.1-SNAPSHOT

Java: 17

Run Configurations

• Use Build Project config to build the plugin.
• Use Run Project to run your plugin in a test server, within IntelliJ.
