Check file exists and skip task in next run playbooks

[Ti_n_Nguy_n (Tiến Nguyễn)]

I write my playbook

• name: stat /opt/zookeeper-3.4.14/*
  stat:
  path: “/opt/zookeeper-3.4.14”
  register: zoo
• name: mv opt/zookeeper-3.4.14 /opt/zookeeper
  shell: mv /opt/zookeeper-3.4.14/* /opt/zookeeper
  when: zoo.stat.exists

I run the command for the first time, every thing is ok.
But from the 2nd run. I get the following error

Is there a way to run this task on the 1st run. Can I skip it on the 2nd run?
Thanks!
