Acquia Pipelines jobs fails with - "The "/tmp/artifact/docroot/core" directory does not exist."
Composer v2.2 has included a new security feature
https://getcomposer.org/doc/06-config.md#allow-plugins. The problem is that, with the new version of composer we have to declare the
allow-plugins config with a list of packages names that are allowed to run code.
As of Composer 2.2.0, the allow-plugins option adds a layer of security allowing you to restrict which Composer plugins are able to execute code during a Composer run.
As a result of this update, Composer commands that are impacted includes
composer create-project and
composer update.This can break continuous integration and deployment workflows, such as Acquia Pipelines, so it is recommended that projects authorise core's required plugins (and projects using development dependencies should authorise development plugins).
You can see similar warnings in the pipelines logs -
drupal/core-composer-scaffold contains a Composer plugin which is blocked by your allow-plugins config. You may add it to the list if you consider it safe. See https://getcomposer.org/allow-plugins
You can run "composer config --no-plugins allow-plugins.drupal/core-composer-scaffold [truefalse]" to enable it (true) or keep it disabled and suppress this warning (false)
Add an "allow-plugins" sub-section in the "config" section of the appropriate composer.json templates. At a minimum you need to add in the following plugins. Depending on your Drupal configuration, you may need to add other plugins which are affected.
"config": {
"sort-packages": true,
"allow-plugins": {
"composer/installers": true,
"drupal/core-composer-scaffold": true,
"drupal/core-project-message": true
}
},
