We have a master pipeline, which is responsible for triggering pipelines from multiple projects and performing some steps. I want to pass a file from first pipelines output to the second one but i am unable to do so. 

```
image:
  name: some-image
  entrypoint: [""]

variables:

stages:
  - create_file
  - print_file
  - consume_file

create_file:
  stage: create_file
  variables:
  trigger:
    project: user-name/project-name
    strategy: depend

print_file:
  stage: print_file
  script:
    - sleep 5
    - cat output_file.txt
  dependencies:
    - create_file

consume_file:
  stage: consume_file
  variables:
  trigger:
    project: user-name/project-name-alternate
    strategy: depend

```

I don't want to resort to scripts instead of trigger. Have tried artifacts etc but i couldn't find a way to pass them on to the next pipelines.

P.s. this is just a sample set out of the pipelines, there are multiple pipelines that are dependent on the output from first pipeline.
