Publish to Maven Central using Gradle and Github Actions

This repo contains a template gradle buildscript and workflow. The workflow can basically be copy-pasted.

I tried to remove anything that is not required and make it as minimal as possible.

How to use with Github actions:

1. Setup the following repository secrets on github:

• GPG_SECRET_KEY: Output of the gpg --export-secret-keys -a <key-id> command
• GPG_SECRET_KEY_PASSWORD: Password of the used key
• SONATYPE_USERNAME: Username for Sonatype
• SONATYPE_PASSWORD: Password for Sonatype

2. When pushing a commit it will automatically publish to Maven Central

How to use without Github actions:

1. Setup gradle.properties like this and make sure you have the gpg key imported:

signing.gnupg.passphrase=Password for used key (Optional)
sonatypeUsername=Username for Sonatype
sonatypePassword=Password for Sonatype

2. run ./gradlew publish closeAndReleaseStagingRepository

In both cases you should be able to access the published dependency after about 30 minutes
