Create a plugin, but it's not showing up under the "Settings -> Plugins" section in Mautic

[prince_kumar]

Your software
My Mautic version is: 5.1.0
My PHP version is: 8.2.23
My Database type and version: MySQL 8.2.23

Your problem
I’m trying to create a plugin, but it’s not showing up under the “Settings → Plugins” section in Mautic.

Sample Code of the Plugin:

1. Created a folder inside plugins/DemoTestBundle
2. Config/config.php:

return [
    'name'        => 'Si Demo',
    'description' => 'Team demo creating a bootstrapped plugin',
    'version'     => '1.0',
    'author'      => 'Team demo'
];

3. composer.json:

{
        "name": "mautic/demotestbundle",
        "description": "A plugin to build DB connections in Mautic.",
        "type": "mautic-plugin",
        "autoload": {
            "psr-4": {
                "MauticPlugin\\DemoTestBundle\\": "plugins/DemoTestBundle"
            }
        }
    }

4. DemoTestBundle.php:

namespace MauticPlugin\DemoTestBundle;
use Mautic\PluginBundle\Bundle\PluginBundleBase;
class DemoTestBundle extends PluginBundleBase
{
    // Nothing more required
}

Steps I Have Tried to Fix the Problem:

1. Cleared the cache in var/cache/prod/
2. Executed composer dump-autoload
3. Cleared the cache using php bin/console cache:clear
4. click on Install / Upgrade Plugins button at right corner in UI setting → plugin
   check log we got a error

Any hints on what might be going wrong?

Kind regards,

Interesting. Can you share your plugin as a Github repo? I’d like to easily replicate this issue. It looks like an issue in Mautic itself.

[prince_kumar]

we just created manually folder

1. Created a folder inside plugins/DemoTestBundle
2. DemoTestBundle/Config/config.php
3. DemoTestBundle/composer.json
4. DemoTestBundle/DemoTestBundle.json

Hmm, I don’t see this ‘autoload’ being used in other plugins. I would test removing this part, or test not having composer.json altogether if its not needed, to see if that helps.

{
        "name": "mautic/demotestbundle",
        "description": "A plugin to build DB connections in Mautic.",
        "type": "mautic-plugin",
    }

[prince_kumar]

yes resolved we removed composer.json
