drupal-finder is unable to find the drupal-root directory when installed in a subdirectory

[JTubex]

Follow-up from issue mentioned in drush-ops/drush#4019.

When Drupal is installed in a subdirectory, drupal-finder is unable to find the drupal-root directory.

To reproduce using drush:

1. e.g. Site is located in /var/www/release/1.0.0/htdocs
2. Create a symlink /var/www/current -> /var/www/release/1.0.0
3. The website is now accessible in /var/www/current/htdocs.
4. Execute drush in /var/www/current/htdocs.

Or see the test in this pull request.

Thanks for the test. Could you try to execute drush in /var/www/current/?

@webflo,

When executing drush cr in /var/www/current, I get the following error:

Command cache-rebuild needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to run this command.                                       [error]
Command cache-rebuild requires Drupal core version 8+ to run.                                                                                                                                    [error]
The drush command 'cr' could not be executed.

Could you run this command with the --debug --verbose? Thanks!

Hi @JTubex, i looked at your test and its not quite correct. testDrupalDefaultStructureWithRealFilesystemInSubdirectory create a Drupal site with the classic layout (composer.json and vendor folder inside the docroot). There is no Drupal site above the webroot. Drush-launcher does not support setups. I wrote a new test (testDrupalComposerStructureWithRealFilesystemInSubdirectory). This tests create a layout similar to drupal-composer/drupal-project. The Drupal Site is accessible above the docroot.

@webflo, thanks for your help. Since drush-ops/drush#4019 is merged, the problem I had is solved, so I will close this PR.
