deploy to Github Package Registry from Github Action

Question

I would like to deploy to a GitHub Package Registry from a GitHub Action of a public repo.

I have a yml file for a workflow:

name: My CI

on: [push]

To make it work, you need to do two things:

1. Add the following to your pom.xml:

   
     github
     GitHub OWNER Apache Maven Packages
     https://maven.pkg.github.com/OWNER/REPOSITORY
   

source: https://help.github.com/en/articles/configuring-apache-maven-for-use-with-github-package-registry#publishing-a-package

2. Setup a Maven settings file with the username/password from within your build action. In my case I did something like this:

name: Java CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v1
    - name: Set up JDK 1.8
      uses: actions/setup-java@v1
      with:
        java-version: 1.8
    - name: Deploy to Github Package Registry
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      run: |
        mkdir ~/.m2
        echo "githubOWNER${GITHUB_TOKEN}" > ~/.m2/settings.xml
        mvn deploy

Unfortunately, I don't think you can pass the username/password as arguments to Maven and so you need to set up the settings file instead. source: Is it possible to pass a password in Maven Deploy in the command line?

Lastly, I confirm that this only works for non-SNAPSHOT artifacts. When I try deploying a SNAPSHOT version it fails with a 400 error as described.
