Run shared dependency only once

[tennox]

I have this kind of task setup:

tasks:
    build:
        deps: [pnpm-install, generate-pwa-icons]
        cmds:
            - pnpm build
    pnpm-install:
        cmds:
            - pnpm install
    generate-pwa-icons:
        deps: [pnpm-install]
        cmds:
            - pnpm pwa-assets-generator

I would expect pnpm-install to only run once, but it runs in parallel, and breaks because it doesn't support that:

❯ task build
task: [pnpm-install] pnpm install
task: [pnpm-install] pnpm install
Scope: all 11 workspace projects
Scope: all 11 workspace projects
 ENOENT  ENOENT: no such file or directory, unlink '/home/manu/dev/tam/wovin/node_modules/.pnpm/node_modules/concurrently'


task: Failed to run task "pnpm-install": exit status 1
task: Failed to run task "pnpm-install": exit status 1

I get that running tasks in parallel makes sense, but I think if a dependency depends on the same task, it should only run that one once. 🤔

Hi @tennox, you might want to look into the run keyword. This will allow you to limit the number of a times a task can be run:

  pnpm-install:
    run: once
    cmds:
      - pnpm install
