Looks like a rebasing went wrong. Temporary fix is too delete the line 35 in the file.

I will submit a PR tomorrow morning.

[AndyXheli]

copy that thank you!

Bugs like these happen easily, but they should never pass the CI. We really should try to make sure that the CI is able to catch stuff like that in some way.

[CarlSchwan]

#1829 would have probably caught it but it's only on master since it's an invasive change.

Only 23 and 22 are affected, 21 and master aren't

[CarlSchwan]

PRs: #1856 and #1857 to fix it

I will try to release a bugfix release tomorrow. Ideally, for the 23 release, #1849 should also be included since it also fixes an important regression.

same to me .. did open a case .. but saw later, case is already open (will close other one)

Actual behaviour
i've got a bash-shell script, which automatically install new app versions, when available.

(may be a bad idea).

After automatic install of "groupfolders new version available: 10.0.1" PHP reports FATAL ERROR.

PHP Fatal error: Cannot use OCP\Constants as Constants because the name is already in use in /var/www/html/nextcloud/apps/groupfolders/lib/Command/ACL.php on line 35

none of the '/var/www/html/nextcloud/occ' commands is working anymore.

Steps to reproduce
disabling the groupfolders app solves the issue.
enabling the groupfolders app triggers the issue.

Expected behaviour
Especially the "FEATURED" Apps should not bring the CORE Cloud function to malfunction.
