I'm trying to fix the build script so I can release phpMyAdmin 5.1.0, but I've hit a strange issue with Composer and the cache warmup.

I've manually defined all the "dev" packages as required, so that whether I run "composer update" or "composer update --no-dev" there are no changes to the installed packages.

# composer update --no-dev

# ./scripts/console cache:warmup --routing
PHP Fatal error:  Uncaught Error: Class 'PhpMyAdmin\Tests\Stubs\DbiDummy' not found in /var/www/pma-dev/fork/release/phpMyAdmin-5.1.0-rc1/scripts/console:41
Stack trace:
#0 {main}
  thrown in /var/www/pma-dev/fork/release/phpMyAdmin-5.1.0-rc1/scripts/console on line 41

But

# composer update

# ./scripts/console cache:warmup --routing

runs correctly...

Any thoughts about this? I'd like to build the release without requiring all of the dev packages, but if I can't warm up the cache as part of the build, on first run phpMyAdmin throws an error message because ./cache/ isn't writable by the webserver process.

Any thoughts about this?
