We’ve made it easy to automatically update your Minecraft server to the latest Paper, Velocity, Waterfall or even Travertine version.

If you’ve ever been frustrated with having to download each individual Paper build, you can now use MineAcademy Endpoint to get the latest jar.

We also provide endpoints for both Spigot and Mojang mappings to Paper.

In this tutorial, I’ll show you what the new endpoint is capable of, and how to configure your Minecraft server using cURL to automatically update Paper.

About Our Endpoint

Endpoint Structure

The structure for our endpoint is as follows:

				
					https://mineacademy.org/api/{software}/{version}

Supported Software

At this time, we support the following software:

  • Paper (use “paper” for Spigot, and “paper-mojmap” for Mojang mappings, see below)
  • Purpur
  • Velocity
  • Folia (please note that these builds appear outdated on Paper)
  • Travertine
  • Waterfall

Please note that the versions are compiled by team Paper, and their availability can be checked at “https://api.papermc.io/v2/projects/X” (replace X with the project name such as folia).

 

Obtaining The Latest Version

The top-most endpoint call will automatically retrieve the latest Paper jar for any Minecraft version.

It is inherently unsafe to use this without strong precaution, as this will serve any given major Minecraft version such as 1.20 and 1.21 as soon as they are available.

We only recommend downloading the latest major version for testing purposes.

				
					https://mineacademy.org/api/paper/latest

If you wish to obtain a jar using Mojang mappings, use “paper-mojmap” instead:

				
					https://mineacademy.org/api/paper-mojmap/latest
				
			
				
					https://mineacademy.org/api/purpur/latest
				
			
				
					https://mineacademy.org/api/folia/latest
				
			
				
					https://mineacademy.org/api/velocity/latest
				
			
				
					https://mineacademy.org/api/waterfall/latest
				
			
				
					https://mineacademy.org/api/travertine/latest

Obtaining The Latest Build For A Given Version

Our endpoint is capable of retrieving the latest Paper build for a given Minecraft version, such as 1.20, 1.20.2 etc.

For all available versions, visit Paper’s build explorer here and see the panel to the left. Then, simply replace the “.” with “_” with the version you would like to obtain the latest build of.

Examples:

Obtaining Minecraft 1.8.8: Please note that if you wish to 1.8.x, there is no such build as 1.8.9 and older versions are no longer officially maintained.

				
					https://mineacademy.org/api/paper/1_8_8

To get 1.20, either type 1_20 for the main version, or specify the subversion like:

				
					https://mineacademy.org/api/paper/1_20_1
				
			
				
					https://mineacademy.org/api/paper/1_20_2

You can use the same logic for Purpur and other software:

				
					https://mineacademy.org/api/purpur/1_20_2
				
			
				
					https://mineacademy.org/api/velocity/3_1_1

It is even possible to obtain a snapshot build of a software, here is an example from Velocity:

				
					https://mineacademy.org/api/velocity/3_2_0-SNAPSHOT

Here is an example of getting Waterfall. Please note that this BungeeCord fork does not have subversions: 

				
					https://mineacademy.org/api/waterfall/1_20

Auto-Download Latest Paper When Launching Your Server

You can use cURL to automatically download the latest software version directly from Paper using our endpoint.

Windows Script Example

Here is an example of a launching script for Windows. Save the content below to a file ending with “.bat” extensions such as “launch.bat”. Please note to change the startup flags according to your preferences.

				
					@echo off

set "jar_url=https://mineacademy.org/api/paper/latest"
set "downloaded_file=paperclip.jar"

curl -o "%downloaded_file%" "%jar_url%"
java -Xms4G -Xmx4G -jar "%downloaded_file%" nogui

pause

Linux And macOS Script Example

And here is an example of a launching script for Linux and macOS. Save the content below to a file ending with “.sh” extensions such as “launch.sh”. Please note to change the startup flags according to your preferences.

				
					@echo off

set "jar_url=https://mineacademy.org/api/paper/latest"
set "downloaded_file=paperclip.jar"

curl -o "%downloaded_file%" "%jar_url%"
java -Xms4G -Xmx4G -jar "%downloaded_file%" nogui

pause

Security Advisory

There are a few downsides to using an endpoint like this.

As mentioned, automatically updating between major game versions will break your plugins and can corrupt your worlds, especially given that the early builds of every new major Minecraft update are inherently unsafe.

Updating between subversions also comes with the same risk.

Therefore, I only recommend doing this “reckless” strategy on a local test server.

The recommended use case for this endpoint is to update builds of the same sub-version, such as to update from build 157 to build 158 of 1.20.2 where breaking changes are minimal.

Still, if you decide to use this endpoint on a production server, you should set a daily backup mechanism in place that is run before the scripts above.

Take care,
