|
|
|
|
|
|
|
|

|
|
|
|
import_tasks.

```yaml
|
2019-06-26 10:11:43 +00:00
|
|
|
- name: Include init tasks
|
|
|
|
import_tasks: init.yml
|
|
|
|
tags:
|
|
|
|
- init
|
|
|
|
when: proof.stat.exists == False
|
|
|
|
```
|
|
|
|
|
|
|
|
`ìnclude_tasks` will add all tasks to play run, even if the when condition is
|
|
