Delete the precondition. Its senseless (IMMHO) to have a task with a precondition, call it, and then have an option to bypass the precondition.

However, what you could is add a task in-between to manage the situation, something like this:

  run_foo:
    vars:
      a:
        sh: echo 1
    cmds:
      - echo {{.a}}
      - task: foo
        ignore_error: true
        vars:
          a: 1
      - echo {{.a}}
      - task: foo_with_precondition
        ignore_error: true
        vars:
          a: 2
  foo_with_precondition:
    preconditions:
      - sh: '[ "{{.a}}" = "2" ]'
    cmds:
      - task: foo
  foo:
    cmds:
    - exit 1

Precondition is really difficult to use, what Task actually needs is branching, I really need if statments to make task go to different sub-task

The ignore_error applies specifically to the task call, and is a duplicate of #855.

status will work better than preconditions for what you are attempting to do. Its logically the inverse of if but you can still do something with that.

An if like item would be a duplicate of #608.
