GitLab CI syntax to write FOR loop statement?

Question

Below is the script mentioned in the gitlab-ci.yml file. This GitLab CI configuration is valid. But, when the CI/CD build is run, the job fails. Is it something to do with the FOR loop syntax?

deploy_dv:
  stage: deploy_dv
  variables:
    GIT_STRATEGY: none
script:
  - echo "Deploying Artifacts..."
  - echo "Configure JFrog CLI with parameters of your Artifactory instance"
  - 'c:\build-tools\JFROG-CLI\jfrog rt config --url  %ARTIFACTORY_WEBSITE% --user %ARTIFACTORY_USER% --apikey %APIKEY%'
  - 'cd ..\artifacts'
  - 'SETLOCAL ENABLEDELAYEDEXPANSION'
  - FOR %%i in (*) do (
        'c:\build-tools\curl\bin\curl.exe --header "PRIVATE-TOKEN:%HCA_ACCESS_TOKEN%" --insecure https://code.example.com/api/repository/tags/%CI_COMMIT_TAG% | c:\build-tools\jq\jq-win64.exe ".release.description" > temp.txt'
         'set /p releasenote=<temp.txt'
         'rem del temp.txt'
         'set mydate=%DATE:~6,4%-%DATE:~3,2%-%DATE:~0,2%'
         'c:\build-tools\JFROG-CLI\jfrog rt u "%%i" %ARTIFACTORY_ROOT_PATH%/%PROJECT_NAME%/%%i --build-name=%%i --build-number=%BUILDVERSION%  --props releasenote=%releasenote%;releaseversion=%BUILDVERSION%;releasedate=%mydate% --flat=false'
     )

    - '%CURL% -X POST -F token=%REPOSITORY_TOKEN% -F ref=master  -F "variables[RELEASE]=false" -F "variables[PROGRAM]=test" --insecure https://code.example.com/api/repository/trigger'

  only:
  - /^(dv-)(\d+\.)(\d+\.)(\d+)$/

I get this below error:

  $ echo "Deploying Artifacts..."
"Deploying Artifacts..."
$ echo "Configure JFrog CLI with parameters of your Artifactory instance"
"Configure JFrog CLI with parameters of your Artifactory instance"
$ c:\build-tools\JFROG-CLI\jfrog rt config --url  %ARTIFACTORY_WEBSITE% --user %ARTIFACTORY_USER% --apikey %APIKEY%

The filename, directory name, or volume label syntax is incorrect.

Answer 1

Since there is still no good answer to this question, I will give it a try. I used this snippet to start multiple Docker builds for every directory in my repository. Notice the >, which lets you put multiline commands in YAML (source).

Linux example:

build:
  stage: loop
  script:
    - >
      for i in $(seq 1 3); do
        echo "Hello $i"
      done

Windows example:

build:
  stage: loop
  script:
    - >
      setlocal enabledelayedexpansion
      for %%a in ("C:\Test\*.txt") do (
        set FileName=%%~a
        echo Filename is: !FileName!
      )
      endlocal
