Failed to execute goal com.microsoft.azure:azure-functions-maven-plugin:1.28.0

Question

Is something wrong with my pom.xml which could be causing GitHub actions to throw an error when trying to Restore Project Dependencies Using Mvn? I have a feeling there is some sort of compatibility issues with the versions being used but cannot tell.

Note: My application works perfectly fine locally. It is a basic application which leverages Java Azure Functions and CosmosDB to write and read data from a DB.

Error:

Local response:

• Pushed the project to GitHub.

Steps to deploy the function using GitHub actions:

• Create a Java Azure Function app in Azure Portal.
• Go to Function app=> deployment=> Deployment Center, select GitHub as Source.
• Sign into your GitHub account and select the repository and branch of your project.

• It automatically creates a workflow under .github/workflows to deploy the function to Azure.

My Workflow:

on:
  push:
    branches:
      - main
  workflow_dispatch:

env:
  AZURE_FUNCTIONAPP_NAME: <function_app_name> # set this to your function app name on Azure
  PACKAGE_DIRECTORY: '.' # set this to the directory which contains pom.xml file
  JAVA_VERSION: '17' # set this to the java version to use

jobs:
  build-and-deploy:
    runs-on: windows-latest
    
    steps:
      - name: 'Checkout GitHub Action'
        uses: actions/checkout@v4

      - name: Setup Java Sdk ${{ env.JAVA_VERSION }}
        uses: actions/setup-java@v1
        with:
          java-version: ${{ env.JAVA_VERSION }}

      - name: 'Restore Project Dependencies Using Mvn'
        shell: pwsh
        run: |
          pushd './${{ env.PACKAGE_DIRECTORY }}'
          mvn clean package
          popd
      
      - name: 'Run Azure Functions Action'
        uses: Azure/functions-action@v1
        id: fa
        with:
          app-name: '<function_app_name>'
          slot-name: 'Production'
          package: '${{ env.PACKAGE_DIRECTORY }}'

          publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_E692B1861D6246058D40E4ADAADA7674 }}
