Drupal console exception

[epfremmer]

My system information:

• Operating system type: macOS
• Operating system version: 10.12.2
• BLT version: 8.6.5

When I run this command:

vendor/bin/drupal list

I get the following output:

Recoverable fatal error: Argument 1 passed to Drupal\metatag\Command\GenerateGroupCommand::__construct() must be an instance of Drupal\metatag\Generator\MetatagGroupGenerator, none given in /var/www/kraken/docroot/modules/contrib/metatag/src/Command/GenerateGroupCommand.php on line 57 #0 /var/www/kraken/docroot/core/includes/bootstrap.inc(548): _drupal_error_handler_real(4096, 'Argument 1 pass...', '/var/www/kraken...', 57, Array)

Recoverable fatal error: Argument 1 passed to Drupal\metatag\Command\GenerateGroupCommand::__construct() must be an instance of Drupal\metatag\Generator\MetatagGroupGenerator, none given in Drupal\metatag\Command\GenerateGroupCommand->__construct() (line 57 of /var/www/kraken/docroot/modules/contrib/metatag/src/Command/GenerateGroupCommand.php).

And I expected this to happen:

normal drupal console command list output

Additional Information:

It looks like BLT is using an earlier version of the drupal/console package. Currently this has a hard version constraint in the blt composer.json locked at 1.0.0-beta5. This in combination with the use of the metatag module produce this exception due to the earlier version of the drupal console instantiating console commands by hand through reflection before they implemented a compiler pass to retrieve them from the service container.

Since the commands included in the metatag module have constructor arguments drupal console is unable to run.

Possible Solutions:

• Change the drupal/console constraint from 1.0.0-beta5 to something less restrictive like ^1.0 to allow console updates as well as more control of the dependency from the project.

@epfremmer Working on an update here: #887

Unfortunately, an update does not resolve the console issue.

@grasmash That is super weird. It does look like it changed the error wherein before we had a missing constructor argument (Drupal\metatag\Generator\MetatagGroupGenerator) it changed to a fatal error thrown in MetatagGroupGenerator when it couldn't autoload the Drupal\Console\Generator\Generator class.

Its as if drupal/console-core wasn't installed or is missing from the autoloader, but I see composer installing it in the build logs.

@epfremmer Drupal console was updated in #887.

@grasmash 👍 thanks again!
