MarsSeed [1] filed a deletion request for ros-noetic-moveit-plugins [2]: Unused, obsolete. Unmaintained on AUR since 2023.
ROS1 Noetic is now EOL. Most of its programs are not compatible with Arch Linux, only with the freshly EOL Ubuntu 20.04 LTS and Python 3.9. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ros-noetic-moveit-plugins/
