gitlab ci: "No files to upload" for job artifacts

Question

This is my first time trying to generate a gitlab-ci job artifact. My ci script generates a csv file that I want to download as an artifact in the job. The yaml file is as below.

   unittest:
      script:
        - cd unittest
        - bash ci-test.sh
      artifacts:
        paths:
          - /*.csv
        when: always
        expire_in: 1 day

I obtained an error msg like this.

Uploading artifacts for successful job
00:02
Uploading artifacts...
WARNING: /*.csv: no matching files 
ERROR: No files to upload 

I have confirmed that the generated csv report is there.

Answer 1

Paths are relative to the project directory. With that said, you cannot access files outside of the project directory, so /*.csv is incorrect.

If files are in the project, then just set path relative to the project, e.g. if you have it in reports folder, then make path equal reports/*.csv

Answer 2

You need to store your output file to $CI_PROJECT_DIR

An example:

test:
  stage: quality
  image: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
  script:
    - cd /app
    - coverage run -m pytest
    - coverage report
    - coverage xml -o $CI_PROJECT_DIR/coverage.xml
  coverage: '/TOTAL.*\s([.\d]+)%/'
  artifacts:
    paths:
      - coverage.xml
    reports:
      cobertura:
        - coverage.xml
