Using ":" in bitbucket pipelines

Hamdi Fourati

Hello,

I'm wondering why bitbucket pipelines are parsing stings inside the script section.

image: ubuntu:18.04

pipelines:
  default:
    - step:
      script:
        -  echo "Echo from pipelines : ${MY_VAR}"

 

This is not valid because of the ":" !!

Hi Hamdi,

The colon character is causing the particular line you have to be parsed as a map instead of a string. This is part of the YAML specification, which the bitbucket-pipelines.yml file follows. Specifically, a colon followed by a space will make the entire line interpreted as a map instead of a string.

There are a few ways to work around this, which will all make the line be interpreted as a string instead.

1. Remove the space after the colon

image: ubuntu:18.04

pipelines:
  default:
    - step:
      script:
        -  echo "Echo from pipelines :${MY_VAR}"

2. Escape the space after the colon

image: ubuntu:18.04

pipelines:
  default:
    - step:
      script:
        -  echo "Echo from pipelines  ${MY_VAR}"

3. Quote the entire command line, which will indicate the line is a string.

image: ubuntu:18.04

pipelines:
  default:
    - step:
      script:
        -  'echo "Echo from pipelines : ${MY_VAR}"'

4. Quote the colon character

image: ubuntu:18.04

pipelines:
  default:
    - step:
      script:
        -  echo "Echo from pipelines ':' ${MY_VAR}"

Thanks,

Phil
