In their own words
Kore
Kore is a Kotlin library for generating Minecraft datapacks from code. It runs during the build and produces ordinary datapack files, so the server does not need Kore or a Kore plugin. Its typed game data can catch errors in items, blocks, sounds, and commands before a datapack is reloaded. The site lists 65+ typed commands, 50+ JSON resource types, and 80+ generated registries. Kore supports commands, recipes, loot tables, advancements, custom dimensions, functions, and predicates; Kotlin functions, loops, and variables can also generate repeated content. If its typed DSL does not cover a command, function bodies can include raw command lines. Existing datapacks can be moved over gradually, with handwritten parts continuing to run alongside generated ones. Kore is available as a Maven Central dependency, and the maker recommends a JDK and Kotlin IDE. An optional Gradle plugin can build, link, and reload a datapack on save. A browser playground can generate a datapack ZIP. The project is free and open source.
