How to create a conditional task in Taskfile?

I have three tasks created with TASKFILE, main-task and its two preconditions(or deps) e.g A and B. I need the main-task to run task A, if task A works fine and did the job then ignore the second task B, otherwise fallback to task B and execute it (that's why I added ignore_error: true). How to put this logic inside main-task using taskfile syntax? thanks

Example:

---
version: 3

tasks:
  A:
    cmds:
      - cmd: exit 1
        ignore_error: true
  
  B:
    cmds:
      - exit 1

  main-task:
    deps: # Run A only, But if it fails then Run B
    cmds:
      - task: # or here: Run A only, But if it fails then Run B
Solution

  • Unfortunately, there isn't a way to run a task only if another one failed. You can run it only if succeeded by calling it after the previous one, or always by using defer.
