Ansible error using `win_copy`: "Unexpected failure during module execution"

Question

I upgraded to Python 3.5 and Ansible deployment started failing, not sure if they are related, but here is the info:

Ansible version: 2.3.2

yaml file:

  - name: Collect compiled DLLs for publishing
    win_copy:
      src: '{{ download_dir }}/tmp/xxxx/bin/Release/PublishOutput/bin/'
      dest: '{{ work_dir }}\bin'

Error:

{
  "failed": true,
  "msg": "Unexpected failure during module execution.",
  "stdout": ""
}

Answer 1

Upgrade to Ansible 2.5.1 to fix this issue.

Summary from the pull request:

When win_copy copies multiple files it can sometimes delete the local tmp folder that should be used by multiple modules. This means any further modules that need to access this local tmp folder will fail.

We never came across this in ansible-test as we ran a Python module on localhost which causes the ansiballz cache to stop win_copy from successfully deleting this folder.
