ansible-下载java jdk-错误：任务'command'中指定了多个操作

Question

Ansible:1.9.2（因此使用wget而不是get_url)。Linux CentOS 6.5

运行以下命令并获得以下错误消息：

$ ansible-playbook site.yml ${sudo_user_opts} -i hosts -u builduser --private-key ${DEPLOYER_KEY_FILE} --extra-vars "svr_type=${server_type} deploy_environment=${DEPLOY_ENVIRONMENT} ansible_user=${ANSIBLE_USER}

ERROR: multiple actions specified in task: 'command' and 'Download Java/JDK Versions'

Answer 1

每个任务只能有1个操作。ansible内置模块debug被视为一个操作，因此您必须使其成为自己独立的任务，如下所示：

- debug: msg="Java {{ item.key }} is (jdk-{{ item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }})"
  with_dict: "{{ java_versions }}"  

- name: Download Java/JDK Versions
  with_dict: "{{ java_versions }}"  
  command: wget -q "{{ item.value.dist_url }}"
    chdir="{{ common_download_dir }}"
    creates="{{ common_download_dir }}/{{ item.value.dist_file }}"
