Staged parallel runs

[misuzu]

I want something weird.

I have A.yml, B.yml and C.yml files with following content:

version: '3'

output: 'prefixed'

tasks:
  build:
    cmds:
      - build command

  deploy:
    cmds:
      - deploy command

I'm using these files in main taskfile:

version: '3'

includes:
  a:
    taskfile: ./A.yml
  b:
    taskfile: ./B.yml
  c:
    taskfile: ./C.yml

tasks:
  a:
    cmds:
      - task: a:build
      - task: a:deploy

  b:
    cmds:
      - task: b:build
      - task: b:deploy

  c:
    cmds:
      - task: c:build
      - task: c:deploy

  all:
    deps:
      - task: a
      - task: b
      - task: c

Is it possible to first run a:build b:build and c:build in parallel and if there is no errors run a: deploy b: deploy and c: deploy also in parallel when I'm starting task all?

Hi @misuzu,

I hope all is well with you and your family in Ukraine!

You need to declare extra tasks to achieve that:

tasks:
  build-all:
    deps: [a:build, b:build, c:build]

  deploy-all:
    deps: [a:deploy, b:deploy, c:deploy]

  all:
    - task: build-all
    - task: deploy-all

A bit of duplication if you also need the old tasks, but it does the trick.
