ansible git 模块不拉代码？

广告编辑添加server_platform_id

这个是我服务器的log:

可以看到服务器的log落后我本地的log
ansible:

---
- hosts: sp
  vars:
    ansible_ssh_pipelining: yes 
  
  tasks:
    - git:
        repo: git@git.coding.net:xxxx/GitName.git
        dest: /home/servername/GitName
         
        
        version: master
        update: yes
        key_file: /home/servername/.ssh/id_rsa
        
        

      notify:
        - restart GitName 
        - restart task-name
      
  handlers:
    - name: restart GitName
      supervisorctl: name=GitName state=restarted 
    - name: restart task-name
      supervisorctl: name=task-name state=restarted     

这个是git的log

changed: [sp] => {"after": "4086a3e3819b8c7df298f1333b060b97c3f35979", "before": "ba3f9d29c63ca96c2829de819d8fd4914160814d", "changed": true, "invocation": {"module_a

ll, "track_submodules": false, "update": true, "verify_commit": false, "version": "master"}, "module_name": "git"}, "warnings": []}    

请问我是哪里错了？
