🐞 Bug Report: Can't install using Composer because of missing composer.json in GitHub tag ZIPs

[kasparsd]

Detailed Description

We're currently excluding composer.json and composer.lock from the git archives (which are used by GitHub tag releases) by setting the following in .gitattributes:

fair-plugin/.gitattributes

Lines 12 to 13 in 707135c

	composer.json export-ignore
	composer.lock export-ignore

Expected Behavior

Users should be able to add this plugin by register this GitHub repository as a Composer repository in their composer.json:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/fairpm/fair-plugin"
        }
    ],
    "require": {
        "fairpm/fair-plugin": "^1.4"
    }
}

which then pulls in the required plugin dependencies required for the functioning of the plugin. At least until we isolate and include in the releases #498.

Current Behavior

The composer require fairpm/fair-plugin step works but on plugin activation users get:

Warning: require_once(/var/www/html/wp-content/plugins/fair-plugin/vendor/autoload.php): Failed to open stream: No such file or directory in /var/www/html/wp-content/plugins/fair-plugin/plugin.php on line 28 Fatal error: Uncaught Error: Failed opening required '/var/www/html/wp-content/plugins/fair-plugin/vendor/autoload.php' (include_path='.:/usr/local/lib/php') in /var/www/html/wp-content/plugins/fair-plugin/plugin.php:28 Stack trace: #0 /var/www/html/wp-settings.php(589): include_once() #1 /var/www/html/wp-config.php(150): require_once('/var/www/html/w...') #2 /var/www/html/wp-load.php(50): require_once('/var/www/html/w...') #3 /var/www/html/wp-admin/admin.php(35): require_once('/var/www/html/w...') #4 /var/www/html/wp-admin/plugins.php(10): require_once('/var/www/html/w...') #5 {main} thrown in /var/www/html/wp-content/plugins/fair-plugin/plugin.php on line 28 

because:

1. we're requiring vendor/autoload.php in the plugin bootstrap file,
2. the composer.json and composer.lock are missing from the releases and fairpm/did-manager-wordpress dependency isn't therefore installed.

Steps to Reproduce

1. See above.

Context (Environment)

• FAIR connect 1.4.0 and earlier versions.

Possible Solution

1. Include composer.json and composer.lock in git archives by updating .gitattributes.
2. Load vendor/autoload.php only if it exists.
