Accessing Server Internals

IMPORTANT

BuildTools is a tool created by the SpigotMC team to build a server jar with Spigot and Bukkit changes, which you can read more about here.

Echo will automatically download, and import that server JAR using BuildTools. You can initiate this process by using echo method in the dependencies block:

Groovy DSL

TODO

Kotlin DSL

echo("1.21.4")

It will subsequently download and import the server internals with Spigot and Bukkit applied to it. This does not include any PaperMC modifications to the server JAR, and if you do need those, check out their plugin.
