[BUG?] How to declare an emtpy variable in Bamboo YAML specs?

fstr

Hi,

I'm using Bamboo v7.0.4.

 

I have created a Bamboo plan with YAML specs and I would like to define an empty plan variable. If a user doesn't provide a value when they trigger the plan, the plan will have a check in place and fail.

I want to avoid using a dummy value as a placeholder value.

 

Bamboo plan as YAML specs to reproduce the issue:

version: 2
plan:
  project-key: ABC
  name: Empty Variable Test
  key: EVT

variables:
  MY_VARIABLE: ""

Using null as a value instead of an empty string, will lead to the same result:

version: 2
plan:
  project-key: ABC
  name: Empty Variable Test
  key: EVT

variables:
  MY_VARIABLE: null

Both will lead to an error when the specs are scanned by Bamboo:

23-Jul-2020 14:25:18	Bamboo YAML import failed: Could not determine YAML document version: variables / MY_VARIABLE: String must not be empty.

 

I flagged this topic as a probable bug, since it's possible to declare an empty variable when you configure a plan manually and it's also possible to then export the plan into Java specs, so I assume Java specs also allow empty variables.

 .variables(new Variable("MY_VARIABLE", ""))

 

I checked the Bamboo bug tracker in advance and couldn't find any related ticket.

 

Cheers

YAML Specs doesn't allow to have empty values for String elements. So only workaround is to use dummy value
