Symfony 2.6 dependencies

[klipach]

In composer.json all Symfony components require version 2.6 or above, but a lot of projects use Symfony 2.3 (like mine) because it is an LTS release. Is it possible to downgrade component versions to 2.3?

Hello @klipach,
I agree we should use the LTS version as the minimum version for Symfony.
Symfony ^2.3 seems the way to go for GrumPHP.
The solution requires some extra testing on all platforms to make sure everything is still working!

The composer.json is changed on the master branch so that you can use Symfony 2.3.

The package we use for git actions, requires symfony process 2.4.
This results in an unresolvable error:
Your requirements could not be resolved to an installable set of packages.

I created a ticket on the official repository:
gitonomy/gitlib#85

When this ticket is resolved, I will be testing with Symfony 2.3 on Linux and Windows.

Yesterday i checked the same solution locally, i had a problem with dependency injection https://github.com/phpro/grumphp/blob/master/resources/config/services.yml#L42 there is no support for expression engine for DI 2.3 https://github.com/symfony/DependencyInjection/blob/2.3/composer.json

This means that the lowest we can currently go without modifying the code is Symfony 2.4.
I will still need to test with version 2.4 to make sure all features will work.

[klipach]

it is no so easy to downgrade to fit Symfony LTS version. I think you can close this ticket.

[veewee]

LTS is probably not possible. But we will aim to make the Symfony version as low as possible.
V2.4 might work. I will keep this ticket open until we tested with some projects.

It seems to work with Symfony 2.4. So that will be our minimum dependency.
