How to deploy to maven central repo

Mar 10, 2024

Yesterday I found dockFX library, when I first try it did not work. Today I manage to upgrade the code to java17 and working with latest javafx21, then I wonder how to deploy this to maven central repository. Took around 3 hours, better to write this down for others.

  1. Go login to https://central.sonatype.com/account I used my gmail login and I was in.
  2. Go to https://central.sonatype.com/publishing/namespaces to create namespace, you need to create a verification repository on github if you want to use io.github.yourusername as explained here
    • my maven namespace
  3. Create your GPG keys and publish the, creating is easy https://central.sonatype.org/publish/requirements/gpg/#generating-a-key-pair
    • And distribute it with gpg --keyserver keyserver.ubuntu.com --send-keys CA925CD6C9E8D064FF05B4728190C4130ABA0F98 explaind here
  4. Copy the user token to your settings xml from https://central.sonatype.com/account that will be usedin deploy
  5. Prepare your pom xml, like below , those plugins required
     <project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
