Magento2 module not getting installed with git clone from local repo

Question

I am trying to install a module Abcd_Core using the command

sudo php bin/magento setup:upgrade

The output does list all the modules except Abcd_Core. Also the app/etc/config.php does not have Abcd_Core in the array.

Here is what I did..

---

The module is located at <magento>/app/code/

The file

app/code/Abcd/Core/registration.php

has the code

\Magento\Framework\Component\ComponentRegistrar::register(
     \Magento\Framework\Component\ComponentRegistrar::MODULE,
     'Abcd_Core',
     __DIR__
 );

In app/code/Abcd/Core/etc folder I have module.xml, di.xml files and a folder adminhtml.

module.xml

 <?xml version="1.0"?>
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
 <module name="Abcd_Core" setup_version="1.0.0" />
 </config>

di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Store\Model\Store" type="Abcd\Core\Model\Store" />
</config>

The app/code/Abcd/Core/etc/adminhtml folder has routes.xml and system.xml.

There is a file app/code/Abcd/Core/Model/Store.php which overrides the functionality of method getBaseUrl().

I tried cleaning the cache and then running the setup:upgrade several times, also tried

sudo php bin/magento module:enable Abcd_Core

but unable to install/enable the module.

Can anyone provide some input on what needs to be corrected?

FYI, I cloned the files from a git repository in my organization.

Thank you, Hari CL

You also need a composer.json file:

{
  "name": "Abcd/Core",
  "description": "la",
  "type": "magento2-module",
  "version": "0.0.1",
  "license": [
    "OSL-3.0"
  ],
  "require": {

  },
  "extra": {
    "map": [
      [
        "*",
        "Abcd/Core"
      ]
    ]
  }
}

Also please clean everything in the var folder and flush the cache. If it still doesn't work, check the var/logs file.
