Replace the path to git by the path of this file in order to stop IntelliJ from messing with your staging area (no config for rename & co).

git_for_intellij.sh

#!/bin/bash
inner() {
    local cmd="$@"
    local REGEX="(^|log.showSignature=false )(add|rm|mv) "
    if [[ $cmd =~ $REGEX ]]; then
        echo 'Stopping IntelliJ from being a not well-behaved git client. See IDEA-194592, IDEA-63391, IDEA-176961, ...' >&2
        return 1
    fi
    git "$@"
}
inner "$@"

👍 😀
