[FIXED] GitLab CI/CD Maven SpringBoot upload *jar error: No such file or directory

Issue

I am trying to setup a Springboot monorepo GitLab Pipeline, but the artifacts couldn#t be found.

mvn job

maven-package:
  stage: package
  inherit:
    default: true
    variables: true
  script:
    - cd springboot
    - mvn clean package -P dev
    - cd target
    - ls -al
  artifacts:
    when: always
    paths:
      - springboot.jar
  tags:
    - docker

$ ls -al

Solution

    default: true
    variables: true
  script:
    - cd springboot
    - mvn clean package -P dev
    - cd target
    - ls -al
  artifacts:
    when: always
    paths:
      - springboot/target/springboot.jar
  tags:
