Specify minimum required task verison.

[sdemura]

While the version: key is nice to specify the Taskfile schema version, it would be nice to have some option to define a minimum required task version to run a task.

For example, a recent change introduced .ROOT_DIR, which is incredibly handy for how I leverage task for my team, but many of my devs are stumbling over that as they haven't bothered to upgrade task yet.

I propopse that in in taskfiles, the version: key be expanded to check for minimum task version.

Example:

version: 3

would be compatible with all 3.x taskfile releases, but...

version: 3.15.2

would cause task to exit non-zero if the task version isn't at least 3.15.2.

I came here looking for this feature as well.

I have a workaround that works for my use case, but it's not the prettiest:

# Specify your desired major version
version: 3

vars:
    TASK_MINOR_VERSION:
        # Store the current minor version of task in an environment variable
        sh: echo "{{.TASK_VERSION}}" | awk -F. '{print $2}'

tasks:
    default:
        preconditions:
            # Ensure we have at least version 3.28
            - sh: 'test {{.TASK_MINOR_VERSION}} -ge 28'

Note, that if you try this:

version: 3.28

You get this error:

task: Taskfile versions greater than v3.8 not implemented in the version of Task

Is this a duplicate of #796 ?

[q0rban]

Since #796 is closed, I'd just like to note that this issue is still not fixed.

Hello @q0rban,
Thanks for your comment. Yes we know, I've made a PR to fix it : #1663

It'll most likely fixed in the next version
