Failed to execute goal org.eluder.coveralls:coveralls-maven-plugin:4.3.0:report on GitHub Actions

Question

I'm trying to set up GitHub Actions for building a maven project with Coveralls on a public repository. For some reason it keeps failing with this error:

Failed to execute goal org.eluder.coveralls:coveralls-maven-plugin:4.3.0:report (default-cli) on project e-shop-manager: Build error: Either repository token or service with job id must be defined -> [Help 1]

I have looked through the coveralls documentation (both plugin and actions-side) to no avail.

Here is the yaml from Actions:

name: Java CI with Maven

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
  
    steps:
    - uses: actions/checkout@v3
    - name: Set up JDK 11
      uses: actions/setup-java@v3
      with:
        distribution: 'adopt'
        java-version: '11'
        cache: 'maven'
    - name: Build with Maven
      run: mvn clean package jacoco:report coveralls:report
    
    - name: Coveralls
      uses: coverallsapp/github-action@master
      with:
        github-token: ${{ secrets.COVERALLS_TOKEN }}

where COVERALLS_TOKEN is my secret token, 100% sure it's been added as a repository secret.

Here is my maven project configuration too:

I couldn't find anything elsewhere other than documentation, since I have pretty much copied configs from docs.

Answer 1

While @Emmanuel Bourg is correct, you also have the option of upgrading to the latest version of the Coveralls Github Action. Anything above v2.0 uses Coveralls' Universal Coverage Reporter as its underlying integration, which natively supports Jacoco format coverage reports.

But an important note about the Coveralls Github Action, which could have been why it wasn't working for you before:

The Coveralls Github Action is the only Coveralls integration that uses a token other than the Coveralls Repo Token to identify your repo to the Coveralls API. Therefore, you'll either want to un-set github-token, or else set it like this:

    github-token: ${{ secrets.GITHUB_TOKEN }}

You can read more details about this in my comments here and here.

Answer 2

The Coveralls GitHub actions isn't necessary when using coveralls-maven-plugin. The token can be specified on the command line (and it will be masqued in the log):

mvn clean package jacoco:report coveralls:report -DrepoToken=${{ secrets.COVERALLS_TOKEN }}
