I have created CI pipeline in gitlab for r-package. I need to capture the lint output and fails the job if there is any lint error. I'm unable to read the output of lintr command.

image: r-base:4.1.2

stages:
  - LintR

LintR:
  stage: LintR
  script:
    - cd .. 
    - R -e "capture.output(lintr::lint_package(\"./test-r/\"), file=\"./lint_output.txt\")"
    - cd isp-r && mv ../lint_output.txt .
  artifacts:
    paths:
      - ./lint_output.txt
    when: always

LintR:
  stage: LintR
  script:
    # redirect lintr stdout and stderr to file

    # fail if file is not empty
    - [ ! -s lint_output.txt ]
