I’m working with GitLab CI and I have a job template that I want to modify. Currently, my job looks like this:

mwaa:dags:test:2.8.1:
  variables:
    AIRFLOW_VERSION: 2.8.1
    PYTHON_VERSION: 3.11
  extends:
    - .template_MWAA:DAGS:Test

This job extends a template that includes before_script, script, and after_script sections. I want to modify the job so that:

1. If there are changes in the airflow-mwaa/requirements/** directory, it should run all sections (before_script, script, and after_script).
2. If there are no changes in the airflow-mwaa/requirements/** directory, it should only run the script section.

Here are the relevant parts of the template:

before_script:
  - echo "Starting .install_dependencies template"
  - pip3 install -r "$CI_PROJECT_DIR/airflow-mwaa/requirements/$AIRFLOW_VERSION/requirements.txt"

script:
  - echo "Starting .template_MWAA:DAGS:Test template"
  - cd "$CI_PROJECT_DIR/airflow-mwaa"
  - airflow db init
  - ./tests-ci.sh

after_script:
  # remove older files from terraform providers cache
  - find "$PIP_CACHE_DIR" -mindepth 1 -mtime +14 -type f -delete
  - find "$PIP_CACHE_DIR" -mindepth 1 -mtime +14 -type d -empty -delete

  stage: Test
  extends:
    - .template_MWAA
  needs: []
  variables:
    PIP_CACHE_DIR: "$CI_PROJECT_DIR/.cache/pip"
    PYTHONPATH: "$CI_PROJECT_DIR/airflow-mwaa/dags"
  cache:
    key: $CI_JOB_NAME_SLUG-python
    paths:
      - .cache/pip
  before_script:
    - echo "Starting .install_dependencies template"
    - pip3 install -r "$CI_PROJECT_DIR/airflow-mwaa/requirements/$AIRFLOW_VERSION/requirements.txt"
  script:
    - echo "Starting .template_MWAA:DAGS:Test template"
    - cd "$CI_PROJECT_DIR/airflow-mwaa"
    - airflow db init
    - ./tests-ci.sh
  after_script:
    # remove older files from terraform providers cache
    - find "$PIP_CACHE_DIR" -mindepth 1 -mtime +14 -type f -delete
    - find "$PIP_CACHE_DIR" -mindepth 1 -mtime +14 -type d -empty -delete
  coverage: '/^TOTALs+d+s+d+s+(d+%)$/'
  artifacts:
    reports:
      junit: $CI_PROJECT_DIR/airflow-mwaa/test_results/report.xml
  rules:
    - if: $CI_COMMIT_REF_PROTECTED == "true"
      when: on_success
      allow_failure: false
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
      changes:
        - airflow-mwaa/dags/**/*
        - airflow-mwaa/tests/**/*
      allow_failure: false
      when: on_success
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
      when: manual
      allow_failure: true
    - when: never

How can I modify my job or template to achieve this conditional execution based on file changes? I’m not sure how to combine the changes condition with selective execution of script sections.

Any help or guidance would be greatly appreciated!
