Gitlab-CI: pass variable to a trigger stage?

How can I calculate a variable in the stage "create_profile", which should then be taken over in the next stage "trigger_upload".

My second pipeline "git-project/profile-uploader" which gets triggered in the stage "trigger_upload" should get this variable.

This is my current approach:

---

variables:
  APPLICATION_NAME: "helloworld"
  APPLICATION_VERSION: "none"

create_profile:
stage: build
script:
 # calculate APPLICATION_VERSION
 - APPLICATION_VERSION="0.1.0"
 - echo "Create profile '${APPLICATION_NAME}' with version '${APPLICATION_VERSION}'"
artifacts:
  paths:
   - profile

trigger_upload:
  stage: release
  variables:
    PROFILE_NAME: "${APPLICATION_NAME}"
    PROFILE_VERSION: "${APPLICATION_VERSION}"
  trigger:
    project: git-project/profile-uploader
    strategy: depend

At the moment the pipeline "git-project/profile-uploader" gets the PROFILE_NAME "hello world" as expected and the PROFILE_VERSION has the value "none". PROFILE_VERSION should have the value "0.1.0" - calculated in the stage "create_profile".

You need to pass the variable via dotenv report artifacts as described in this answer. So applied to your example the pipeline will look like this:

variables:
  APPLICATION_NAME: "helloworld"
  APPLICATION_VERSION: "none"

stages:
  - build
  - release

create_profile:
  stage: build
  script:
  # calculate APPLICATION_VERSION
    - echo "APPLICATION_VERSION=0.1.0" >> build.env
    - echo "Create profile '${APPLICATION_NAME}' with version '${APPLICATION_VERSION}'"
  artifacts:
    paths:
      - profile
    reports:
      dotenv: build.env
    
trigger_upload:
  stage: release
  variables:
    PROFILE_NAME: "${APPLICATION_NAME}"
    PROFILE_VERSION: "${APPLICATION_VERSION}"
  trigger:
    project: git-project/profile-uploader
    strategy: depend
  needs:
    - job: create_profile
      artifacts: true
