Composer plugin that allows to download a specified artifact instead of the default dist URL, this allows to download all artifact dependencies too.

Note: version 2.x of Composer Artifacts only works with Composer 2.x and only supports ZIP artifacts.

Table of contents:


The recommended way of installing the plugin is via Composer.

composer require openeuropa/composer-artifacts


Edit the composer.json file and add the following in your extra section:

    "extra": {
        "artifacts": {
            "foo/bar": {
              "dist": {
                "url": "{name}/releases/download/{version}/{project-name}-{version}.zip",
                "type": "zip"

This will fetch dist content from:"

Valid type values are tar and zip while available URL replacement tokens are:

  • {name}: the full package's name without version info, e.g. foo/bar
  • {vendor-name}: just the vendor name, e.g. foo
  • {project-name}: just the project name, e.g. bar
  • {pretty-version}: the pretty (i.e. non-normalized) version string of this package, e.g. 0.1.0
  • {version}: the full version of this package, e.g.
  • {stability}: the stability of this package, e.g. dev, alpha, beta, RC or stable
  • {type}: the package type, e.g. library
  • {checksum}: the SHA1 checksum for the distribution archive of this version

Development setup

Using Docker Compose

Alternatively, you can build a development environment using Docker and Docker Compose with the provided configuration.

Docker provides the necessary services and tools needed to get the tests running, regardless of your local host configuration.



By default, Docker Compose reads two files, a docker-compose.yml and an optional docker-compose.override.yml file. By convention, the docker-compose.yml contains your base configuration and it's provided by default. The override file, as its name implies, can contain configuration overrides for existing services or entirely new services. If a service is defined in both files, Docker Compose merges the configurations.

Find more information on Docker Compose extension mechanism on the official Docker Compose documentation.


To start, run:

docker-compose up

It's advised to not daemonize docker-compose so you can turn it off (CTRL+C) quickly when you're done working. However, if you'd like to daemonize it, you have to add the flag -d:

docker-compose up -d


docker-compose exec web composer install

Running the tests

To run the grumphp checks:

docker-compose exec web ./vendor/bin/grumphp run

To run the phpunit tests:

docker-compose exec web ./vendor/bin/phpunit

Step debugging

To enable step debugging from the command line, pass the XDEBUG_SESSION environment variable with any value to the container:

docker-compose exec -e XDEBUG_SESSION=1 web <your command>

Please note that, starting from XDebug 3, a connection error message will be outputted in the console if the variable is set but your client is not listening for debugging connections. The error message will cause false negatives for PHPUnit tests.

To initiate step debugging from the browser, set the correct cookie using a browser extension or a bookmarklet like the ones generated at
