I'm installing drush v9 on the server as well as I try to port my command. I did several things but now get the error:

drush status

In BespokeDocBlockParser.php line 65:

  Could not determine command name from tag @command

I really have no idea where to look. I googled for the php file but could not even find it :-(

Any suggestion is appreciated. ...

I removed the drush.services.yml and rebuild the cache. Drush status is now giving normal feedback so probably it is sometiming in the drush command.

My drupal.services.yml

    class: \Drupal\tb\Commands\TbCommands
      - { name: drush.command }

My generated php template


namespace Drupal\tb\Commands;

use Drush\Commands\DrushCommands;

 * A Drush commandfile.
 * In addition to this file, you need a drush.services.yml
 * in root of your module, and a composer.json file that provides the name
 * of the services file to use.
 * See these files for an example of injecting Drupal services:
 *   - http://cgit.drupalcode.org/devel/tree/src/Commands/DevelCommands.php
 *   - http://cgit.drupalcode.org/devel/tree/drush.services.yml
class TbCommands extends DrushCommands {

   * Start data collecting for the traderbot
   * @param $para
   *   parameters in case i need this
   * @validate-module-enabled tb
   * @command 
   * @aliases tb,traderbot

    public function traderbot($para) {
      // See bottom of https://weitzman.github.io/blog/port-to-drush9 for details on what to change when porting a
      // legacy command.

    tb_log(3,'Start runnning traderbot from drush');

    tb_log(3,'End runnning traderbot from drush');



The composer.json

    "name": "org/tb",
    "description": "This extension provides new commands for Drush.",
    "type": "drupal-drush",
    "authors": [
            "name": "Author name",
            "email": "author@example.com"
    "require": {
        "php": ">=5.6.0"
    "extra": {
        "drush": {
            "services": {
                "drush.services.yml": "^9"

function tb_log is part of the custom tb drupal module.

What is wrong?


The comment on the traderbot method is incorrect:

   * @command 
   * @aliases tb,traderbot

There is no value after @command. I believe you want:

   * @command traderbot
   * @aliases tb

See: Porting Commands to Drush 9

Clear the cache after the change and try again.

    Yes this is working. Very odd that drush 9 uses things in comment to have this working...

  • Drupal 8 etc makes a lot of usage of Annotations for definition and discovery. It’s new for 8.x devs but not necessarily a new paradigm.
