Symfony 4-不再自动发现3rd-party捆绑包命令 [英] Symfony 4 - 3rd-party bundle commands are no longer automatically discovered

问题描述

根据文档，命令类必须扩展Command或ContainerAwareCommand以自动发现并注册(当然，前提是其捆绑包已在内核中注册).

According to the documentation, a command class must extend Command or ContainerAwareCommand to be automatically discovered and registered (provided its bundle is registered in the Kernel, of course).

自Symfony 4+起，此发现无法按预期进行.

Since Symfony 4+, this discovery doesn't work as expected.

尝试一下:

composer create-project symfony/skeleton test-maxmind-sf4
cd test-maxmind-sf4
composer req cravler/maxmind-geoip-bundle dev-master
php bin/console list

您会注意到:

• cravler:maxmind:geoip-update未注册("cravler"命名空间下没有任何内容
• Cravler \ MaxMindGeoIpBundle \ Command \ UpdateDatabaseCommand扩展了ContainerAwareCommand
• 在所有环境下，config.bundles.php中都会注册Bundle Cravler \ MaxMindGeoIpBundle \ CravlerMaxMindGeoIpBundle(自动生成的配方)

现在，当我对Symfony 3进行完全相同的操作时，一切正常.

Now when I do exactly the same thing with Symfony 3, everything works properly.

composer create-project symfony/skeleton test-maxmind-sf3 ^3.0
cd test-maxmind-sf3
composer req cravler/maxmind-geoip-bundle dev-master
php bin/console list

那里缺少什么?

谢谢

推荐答案

来自UPGRADE FROM to 4.0指南

不支持依赖基于约定的命令发现 不再.请改用基于PSR-4的服务发现.

Relying on convention-based commands discovery is not supported anymore. Use PSR-4 based service discovery instead.

之前:

# app/config/services.yml
services:
    # ...

    # implicit registration of all commands in the `Command` folder

之后:

# app/config/services.yml
services:
    # ...

    # explicit commands registration
    AppBundle\Command\:
        resource: '../../src/AppBundle/Command/*'
        tags: ['console.command']
