PHP Composer does not detect the composer.json file: No applications were found

Symptoms

• A composer.json file has been placed into /var/www/vhosts/example.com/httpdocs directory
• Pressing the Domains > example.com > PHP Composer > Scan button does not detect any applications - the following generic message is displayed:

The domain was scanned. No applications were found

• The example.com subscription has several secondary domains.

Cause

The example.com domain's document root folder is shared across several domains and it is excluded from the scan. This is expected behavior according to the PHP Composer scanning logic.

A request EXTPHPCOMP-173 has been created to improve the generic "No applications were found" message to communicate the cause of this issue more clearly.

Resolution

As a workaround, consider one of the following options:

• Either move the composer.json file from the example.com domains's document root folder to the home directory:

# mv /var/www/vhosts/example.com/httpdocs/composer.json /var/www/vhosts/example.com/

Note: Doing this will make the PHP Composer scan the entire /var/www/vhosts/example.com/ directory and all subdirectories

• Or change the example.com domain's document root directory to a separate one in Domains > example.com > Hosting Settings. Alternatively, reconfigure all the secondary domains to use a separate document root directory.
