Compatibility with Composer 2

[prudloff-insite]

This plugin is currently not compatible with Composer 2:

The "drupal/console-extend-plugin" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0").

Here is what needs to be changed: https://github.com/composer/composer/blob/2.0.0-alpha1/UPGRADE-2.0.md#for-integrators-and-plugin-authors

[Eduardo-Morales-Alberti]

Same error here.

Since the release of Composer 2.x this issue is (about to be) breaking in many projects. The related PR seems pretty decent. Would love to see it merged in this package.

Getting the following error:

$ composer update --no-plugins

You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

@atarim-info I found I had to do the following little three-step dance:

1. rm composer.lock
2. composer update --no-plugins
3. composer update

Sorry, that doesn't work:

Same here. Non of the steps above works. I also tried to nuke everything;

1. rm composer.*
2. rm -fr vendor
3. composer require 'drush/drush:^8.0'

still get:

The "drupal/console-extend-plugin" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.
The "dealerdirect/phpcodesniffer-composer-installer" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.

Drush do start though without any warnings

drush --version

Drush Version   :  8.4.5

[pefferen]

@steinmb those packages are not a dependency of Drush.
Possibly the packages are locked by some other dependency(or directly) in your projects composer.json. The latest version of 'dealerdirect/phpcodesniffer-composer-installer' is compatible with Composer 2.x

[steinmb]

Thank you for your swift reply.
My composer.json only have one requirement:

"require": {
        "drush/drush": "^8.0"
}

@atarim-info : The following composer.json file works for me:

{
    "require": {
        "drush/drush": "^8.0",
	"drupal/console-extend-plugin": "dev-master"
    },
    "repositories": [
        {
    	    "type": "vcs",
	    "url": "https://github.com/ossobuffo/drupal-console-extend-plugin.git"
        }
    ]
}

I can do a composer install using Composer 2 with no conflicts. Note that I am pulling drupal/console-extend-plugin from my own repo because the latter's own composer.json must be updated to declare that it is compatible with Composer's v2 API. (Once this PR is merged, this magic will no longer be necessary.)

Adding link #25.

[phox4ever]

I also needed to add an inline alias to get @ossobuffo's magic to work temporarily with drupal/console:
"drupal/console-extend-plugin": "dev-master as 0.9.4"

[natts1]

When will this project be updated for Composer 2 compatibility? Instructions are here

[ChrisScrumping]

I also had to add to temp fix as per Phox4ever to get this working for durpal console

[BrianGilbert]

Works with Composer 2 as of 0.9.5 tag that @jmolivas rolled today
