Setup

This page covers how to quickly get ASP up and running on your server.

Install Java

Since Minecraft version 1.20.6, Java 21 is required to run the server.

Windows

We suggest installing Adoptium JDK 21

Ubuntu/Debian

apt update && apt install temurin-21-jdk

Download Advanced Slime Paper / Pufferfish / Purpur

ASP is actively developed for Paper; Pufferfish and Purpur versions are based on it, but updated less frequently.

ASPaper

We recommend using the Paper version for the most stable experience. AdvancedSlimePaper builds are split into several branches, including main, develop, and various feature or PR branches.

The main branch is stable and well-tested, but it may not always include the latest Paper commits. For bleeding-edge updates, see paper_upstream, which includes untested automatic changes.

The develop branch is experimental — it’s generally up-to-date with the latest features and versions, but may include a few bugs.

All other branches should be considered highly unstable. These may include breaking API changes, incomplete features, or unsafe third-party code from pull requests.

Next steps

At this moment, ASP is only a server providing the ASP API, nothing else. If you don't want to use the API, or want a utility plugin, we recommend installing the SlimeWorldPlugin
