My Custom drupal 8 module does not shown in modules list I'm developing my first drupal 8 module, a custom migration module, the info.yml file is written as follow :

name : Drupal Center Custom Migrate
description : This module provides custom migration configuration and plugins to migrate my custom site from drupal 6.
type : module
core : 8.x

package : Custom migrate
dependencies :
  - migrate
  - migrate_plus
  - migrate_tools
  - migrate_upgrade
  - migrate_drupal


The above code is saved as dc_custom_migrate.info.yml . This module also provides some config migration file and some custom source plugins.

The problem is my custom module is not shown up in modules list.

I can't figure it up where am I doing wrong!!!

PS. I'm developing in windows 10 environment and using Aquia Dev Desktop 2 as web service simulator.
Remove the spaces between the identifiers and colons:

name: Drupal Center Custom Migrate
description: This module provides custom migration configuration and plugins to migrate my custom site from drupal 6.
type: module
core: 8.x

package: Custom migrate
dependencies:
  - migrate
  - migrate_plus
  - migrate_tools
  - migrate_upgrade
  - migrate_drupal


Then it'll work.

See the YAML rules for more info.
