Release Info

PaperMC Version Mapping

Here's a list of the PaperMC versions and the versions of this latest compatible version.

PaperMC	ExamplePlugin
1.21.7	4.0.15+
1.21.6	4.0.14
1.21.5	4.0.12
1.21.4	4.0.7

1.18.2	3.0.2
1.17.1	2.2.0
1.16.5	2.1.2

This chart would make more sense if this plugin actually did anything and people would have a reason to be looking for older releases to run on older servers.

To use this as a template, just use the latest version of this project and update the PaperMC version as needed. See more info on release stability below.

Release and Versioning Strategy

Stable versions of this repo are tagged vX.Y.Z and have an associated release.

Testing versions of this repo are tagged vX.Y.Z-RC-N and have an associated pre-release.

Development versions of this repo are pushed to the master branch and are not tagged.

Event	Plugin Version Format	CI Action	GitHub Release Draft?
PR	yyMMdd-HHmm-SNAPSHOT	Build and test	No
Cron	yyMMdd-HHmm-SNAPSHOT	Build, test, and notify	No
Push to main	0.0.0-SNAPSHOT	Build, test, release, and notify	No
Tag vX.Y.Z-RC-N	X.Y.Z-SNAPSHOT	Build, test, release, and notify	Pre-release
Tag vX.Y.Z	X.Y.Z	Build, test, release, and notify	Release

Discord Notifications

In order to use Discord notifications, you will need to create two GitHub secrets. DISCORD_WEBHOOK_ID should be set to the id of your Discord webhook. DISCORD_WEBHOOK_TOKEN will be the token for the webhook.

You can find these values by copying the Discord Webhook URL:
https://discord.com/api/webhooks/<DISCORD_WEBHOOK_ID>/<DISCORD_WEBHOOK_TOKEN>

Optionally, you can also configure DISCORD_RELEASE_WEBHOOK_ID and DISCORD_RELEASE_WEBHOOK_TOKEN to send release announcements to a separate channel.

For more information, see Discord Message Notify.

I've broken the rest of the changes up by their files to make things a bit easier to find.

Creating a Release

Below are the steps you should follow to create a release.

1. Create a tag on main using semantic versioning (e.g. v0.1.0)
2. Push the tag and get some coffee while the workflows run
3. Publish the release draft once it's been automatically created

Building locally

Thanks to Gradle, building locally is easy no matter what platform you're on. Simply run the following command:

./gradlew build

This build step will also run all checks and tests, making sure your code is clean.

JARs can be found in build/libs/.
