Unarchive module overwriting - Ansible

Question

I have an ansible playbook that downloads file from the internet and unarchives them and then sends them to another host machine. 

- hosts: group1
sudo: yes
tasks:

  - name: Download and Extract apache
  unarchive:
   src: http://mirrors.up.pt/pub/apache/tomcat/tomcat-9/v9.0.1/bin/apache-tomcat-9.0.1.tar.gz
   dest: /opt/
   remote_src: yes

- name: Copy file to host
  copy: src=/etc/ansible/files/myfile.xml dest=/opt/apache-tomcat-9.0.1/conf/myfile.xml

But everytime I use the unarchive module, ansible is overwriting files with the same content.

Hey @joe, you can use the create option, something like this:

- unarchive:
    remote_src : yes
    src        : "{{ url }}"
    dest       : "{{ install_dir }}/"
    creates    : "{{ flagFile }}" 

This creates a flag that will prevent the overwritten if the same content is already present.
