Variables don't work at the beginning of a command

[fschoell]

See this example Taskfile.yaml

version: '3'

vars:
  BUILD_FLAGS: 'GOOS=linux GOARCH=amd64'

tasks:
  build:
    cmds:
      - {{.BUILD_FLAGS}} go build

Result: Running task build fails with the following error:

task: Failed to parse Taskfile.yaml:
yaml: line 8: did not find expected '-' indicator

Expected behaviour: task build properly executing GOOS=linux GOARCH=amd64 go build

• Task version: 3.32.0
• Operating system: MacOS 14.1.1
• Experiments enabled: no

You need to quote your command string:

version: '3'

vars:
  BUILD_FLAGS: 'GOOS=linux GOARCH=amd64'

tasks:
  build:
    cmds:
      - '{{.BUILD_FLAGS}} go build'
