Composer 2.9 Broken GitHub Actions CI #12600
Description
Following the release of Composer 2.9, the following error has began appearing in our GitHub Actions CI:
Here is the yml file of the failing script:
name: Run PHPUnit Tests
on:
pull_request:
branches: [ master ]
concurrency:
group: phpunit-tests-${{ github.ref }}
cancel-in-progress: true
jobs:
phpunit-tests:
runs-on: ubuntu-latest
timeout-minutes: 10
steps:
- name: Checkout code
uses: actions/checkout@v4
- name: Setup PHP
uses: shivammathur/setup-php@v2
with:
php-version: '7.4'
coverage: none
tools: composer:v2
- name: Install dependencies
run: composer install --no-interaction --no-progress --prefer-dist
- name: Run PHPUnit
run: composer test
Locking the Composer version to 2.8.4 (i.e. tools: composer:2.8.4) fixes the issue.
