GitHub Package Registry with Maven causes deployment issues (Error Code: 400)

[loefflefarn]

We have problems publishing GitHub packages for our internal libraries when we switch to GitHub. Our projects are based on Maven. When publishing to GitHub packages we get the following error:

Some files that are needed are not uploaded. But some will be published anyway. The problem only occurs after the initial version of GitHub Packages has been published. All other publications are buggy. 

We have created the following project as an example: https://github.com/avides/packages-example-for-support

We have used the following GitHub Actions workflow:

name: release

on:
  push:
    branches:
      - master

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - name: setup-java
        uses: actions/setup-java@v1
        with:
          java-version: 11

      - name: setup-maven-settings
        uses: s4u/maven-settings-action@v1
        with:
          servers: '[{"id": "github", "username": "x-access-token", "password": "${GITHUB_TOKEN}"}]'

      - name: checkout
        uses: actions/checkout@v1

      - name: deploy
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: mvn deploy

In the executed actions you can see that initially everything worked fine and no further deploy process worked afterwards.

Please turn off the wagon http pool for maven deploy, command as below, it works on my end. :)

mvn -B -e -Dmaven.wagon.http.pool=false clean deploy

Please refer to the ticket for more details.

I have the same issue but using the command `mvn -B -e -Dmaven.wagon.http.pool=false clean deploy  -DskipTests` gives me same error
