Description
Updates composer dependencies so that they are compatible with Drupal 8.4's dependencies.
Drush 8 is not compatible with Drupal 8.4 (
drupal/core:8.4.0
) -- the Drush 9 update is required. However, thecontinuousphp/phing-drush-task
package declares a dependency on Drush6.5 - 8.1
, which prevents the Drush update (and therefore the Drupal 8.4 update). To work around this, we require Drush 9 but alias the version to 8.1, so that it fulfills both the Drupal 8.4 requirements AND thecontinuousphp/phing-drush-task
requirements.I prefer this approach to using a forked repo for
continuousphp/phing-drush-task
(weitzman, froboy), since we can reference the original repository and receive updates from there once they eventually come through.Unfortunately, Drush usage has changed significantly between Drush 8 and 9, since Drush is now built on
symfony/console
. This means thatpalantirnet/the-build
andcontinuousphp/phing-drush-task
needed updates too.
