I am getting some old and mixed documentation issues with building a release for a Drupal 8-based distribution Drupal.org.
The main documentation is How to package a distribution on Drupal.org, which says to use
drush make to create a drupal-org.make file. However, when I try to run this command on my site, I get the following error message.
Make has been removed, in favor of Composer. Use the make-convert command in Drush 8 to quickly upgrade your build to Composer.
That's fine, since I am already using Composer for the project! But how do I actually then publish these dependencies on Drupal.org? Drupal.org is definitely not reading the composer.json file, and building the zip files.
Do I just have to manually make a git tag which includes all the files in the *vendoré directory, so that Drupal.org knows to build this?
I am running Drush version 9.5.2.
