Generate a personal access token (classic) to access maven reposiotry

[pawel-jedruch-swiftpay]

We do have two private repositories in our organization, let's call them: library and project. The library is hosted in the Maven GitHub repository. The project workflow is using a personal access token for authorization (according to documentation.

Now we want to migrate to actions/create-github-app-token, but I was unable to create a working solution.

.github/workflows/example.yml

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v4

    - name: Get token from Github App
      uses: actions/create-github-app-token@v1
      id: app-token
      with:
        app-id: ${{ secrets.GET_TOKEN_APP_ID }}
        private-key: ${{ secrets.GET_TOKEN_APP_PRIVATE_KEY }}
        owner: ${{ github.repository_owner }}
 
    - name: Set up Maven
      uses: actions/setup-java@v4
      with:
        java-version: '17'
        distribution: 'corretto'
        cache: 'maven'
        server-username: MAVEN_USERNAME
        server-password: MAVEN_PASSWORD

    - name: Build and Package
      run: |
        cd project
        mvn clean package
      env:
        MAVEN_USERNAME: ${{ github.actor }}
        MAVEN_PASSWORD: ${{ steps.app-token.outputs.token }}

I've tried multiple configurations but always end up with the following error:

Authentication failed for https://maven.pkg.github.com//repo/..., status: 401 Unauthorized -> [Help 1]

What I'm guessing is that create-github-app-token doesn't support a personal access token. Could you confirm if this is the case?

That is correct, actions/create-github-app-token creates installation access token (server-to-server tokens). Personal access tokens cannot be created programmatically without user interaction.

Authentication failed for https://maven.pkg.github.com//repo/...

The // looks odd, maybe an argument is missing, like an org name? I'm not familiar with maven I'm afraid
