无法从ansible安装jenkins

我想自动安装jenkins，为此我使用ansible . 我正在尝试用它的repo和gpg键安装jenkins . 这是我的剧本

---
- hosts: "{{ HOST }}"
  become: true
  become_user: root
  gather_facts: true
  become_method: sudo

  vars:
    temp_folder: /tmp

  tasks:
    - name: Include variables
      include_vars:
        dir: '../vars'
        extensions: ['yml']

    - name: Install java  
      yum:    
        name: java    
        state: present    
        update_cache: yes
      become: true
      become_user: root

    - name: Add Jenkins Repository | Add Sources List
      yum_repository:
        name: jenkins
        description: jenkins
        baseurl: "{{ jenkins_repo }}"
        gpgkey: "{{ jenkins_key }}"
        gpgcheck: yes
      become: true
      become_user: root

    - name: Install jenkins 
      yum:
        name: jenkins
        state: present    
        update_cache: yes
      become_user : root
      become: true

    - name: Start Jenkins Service | Enable on Boot
      service:
        name: jenkins
        state: started
        enabled: yes
      become: true
      become_user: root

var文件中的值包含以下键： - ---

jenkins_key: https://pkg.jenkins.io/redhat/jenkins.io.key
jenkins_repo: https://pkg.jenkins.io/redhat/jenkins.repo

现在，当我执行playbook时，它会让我跟随错误 .

    "failed": true,

        }
    },

}

但是当我试图手动添加jenkins repo时，它并没有给我任何错误 .
