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
