Run cmd from env: did not find expected '-' indicator

[Antonboom]

• Task version:

  task --version
  Task version: 3.0.1

• Operating System:

Example Taskfile showing the issue

version: '3'

silent: true

vars:
  APP: ./bin/some-backend

tasks:
  version:
    desc: Show app version.
    cmds:
      - {{.APP}} version

▶ task  version
yaml: line 11: did not find expected '-' indicator

But this works ok:

    cmds:
      - "{{.APP}} version"

▶ task  version

release: "taskfile"
buildDate: "2021-03-17T12:33:34"
branch: "taskfile"

Hi @Antonboom, thanks for opening this issue!

This is an YAML parse issue. YAML disallows { after -, so there's nothing we can do about it. Sorry.

You just need to quote the string as you did in your second example.

Thanks!

@andreynering It'll be nice if comment about this behaviour could be added to the documentation

@MrBr-github if this happens to be a common pitfall, I don't mind a small note/reminder about this somewhere in the docs.

However, it's out of scope for task to also document how yaml works. There is a link on the home page though to the YAML Schema

I'm making a note to add this documentation at minimum for v4.
