MarsSeed [1] filed a deletion request for ros-melodic-moveit-commander [2]: Broken since at least mid-2023 (like practically all ros-melodic packages on AUR*). Now also missing a dependency. Abandoned on AUR since 2021 (like most AUR ros-melodic packages). (* The majority of the ros-melodic non-metapackages try to execute a script named 'python-scripts.sh' from AUR/ros-build-tools, which the latter does not carry.) ROS Melodic distribution is based on Ubuntu 18.04 LTS. Both are EOL since mid-2023. On Arch, it is likely that a large proportion of these abandoned distro package became broken even earlier, in 2021 or 2022.
