Description

Hi. I do deploy on 2 hosts. When I do "dep deploy my_stage -vvv" everything is ok. But when I do "dep deploy my_stage -vvv --parallel", deploy falls with "SymfonyException The "stage" argument does not exist". It rises on the line with "$stage = input()->getArgument('stage');"

Steps to reproduce

Content of deploy.php

<?php

namespace Deployer;

require 'vendor/deployer/deployer/recipe/common.php';

set('repository', 'git@some/repo.git');
set('git_cache', true);
set('shared_dirs', ['tmp/logs']);
set('writable_dirs', ['tmp/cache', 'tmp/twig']);
set('writable_mode', 'chmod');
set('keep_releases', 10);
set('ssh_multiplexing', false);

host('node1')
    ->hostname('some_hostname1')
    ->user('user')
    ->configFile('~/.ssh/config')
    ->identityFile('~/.ssh/id_rsa')
    ->port(12345)
    ->stage('my_stage')
    ->set('branch', 'master')
    ->set('deploy_path', '/home/user/site');

host('node2')
    ->hostname('some_hostname2')
    ->user('user')
    ->configFile('~/.ssh/config')
    ->identityFile('~/.ssh/id_rsa')
    ->port(12346)
    ->stage('my_stage')
    ->set('branch', 'master')
    ->set('deploy_path', '/home/user/site');

// Composer
desc('Installing Composer dependencies');
task('deploy:vendors', function () {
    $stage = input()->getArgument('stage');

    run("cd {{release_path}} && php composer.phar install --working-dir=vendor/{$stage} --prefer-dist --no-dev");
});

desc('Deploy project');
task('deploy', [
    'deploy:prepare',
    'deploy:lock',
    'deploy:release',
    'deploy:update_code',
    'deploy:shared',
    'deploy:writable',
    'deploy:vendors',
    'deploy:symlink',
    'deploy:unlock',
    'cleanup',
    'success'
]);

after('deploy:failed', 'deploy:unlock');

Output log
