Configuration

Make sure you have a drupal-composer/drupal-project-based project created.

Rename your Acquia repo docroot directory to app.

mv docroot app

Update the composer.json of your root package with the following changes:

"extra": {
    "installer-paths": {
        "app/core": ["type:drupal-core"],
        "app/libraries/{$name}": ["type:drupal-library"],
        "app/modules/contrib/{$name}": ["type:drupal-module"],
        "app/profiles/contrib/{$name}": ["type:drupal-profile"],
        "app/themes/contrib/{$name}": ["type:drupal-theme"],
        "drush/contrib/{$name}": ["type:drupal-drush"]
    },
    "drupal-paranoia": {
        "app-dir": "app",
        "web-dir": "docroot"
    }
    "..."
}

Use composer require ... to install this Plugin on your project.

composer require jkribeiro/drupal-composer-paranoia-acquia:~1

Run the following commands to make sure that the new folders are installed:

composer drupal:paranoia
composer drupal:paranoia-acquia

Done! Plugin and new docroot are now installed.

Folder structure

Your project now is basically structured on two folders.

• app: Contains the files and folders of the full Drupal installation.
• docroot: Contains only the symlinks of the assets files and the PHP stub files from the app folder.

Every time that you install or update a Drupal package via Composer, the docroot folder is automatically recreated.

If necessary, you can rebuild it manually, running the command

composer drupal:paranoia

This could be necessary when updating themes images, CSS and JS files.

Last step is to commit and push the changes to Acquia Cloud git repository.
