Gitlab CI / CD s3上传作业一次完成

Question

我已经配置了gitlab ci / cd管道，以便当某人合并到Development分支时，gitlab为stag环境和prod环境进行两个构建，然后根据环境将war包上传到两个s3位置

image: registry.gitlab.com/group/project/imangename:latest

stages:
  - build
  - deploy

before_script:
  - chmod +x mvnw
  - export JAVA_HOME="/opt/jdk1.8.0_131"

build_stag:
  stage: build
  script:
    - ./mvnw clean
    - ./mvnw -Pstag package -DskipTests
  artifacts:
    paths:
      - target/ROOT.war.original
      - scripts/*
      - appspec.yml
  only:
    - Development

deploy_stag:
  stage: deploy
  image: registry.gitlab.com/gitlab-org/cloud-deploy/aws-base:latest 
  script:
    - cp target/ROOT.war.original target/ROOT.war
    - apt-get install zip -y
    - zip MyApplication.zip  appspec.yml scripts/stop_application scripts/start_application scripts/basic_health_check.sh
    - aws s3 cp MyApplication.zip s3://stag-bins/
  only:
    - Development

build_prod:
  stage: build
  script:
    - ./mvnw clean
    - ./mvnw -Pprod package -DskipTests
  artifacts:
    paths:
      - target/ROOT.war.original
      - scripts/*
      - appspec.yml
  only:
    - Development


deploy_prod:
  stage: deploy
  image: registry.gitlab.com/gitlab-org/cloud-deploy/aws-base:latest # see the note below
  script:
    - cp target/ROOT.war.original target/ROOT.war
    - apt-get install zip -y
    - zip MyApplication.zip  appspec.yml scripts/stop_application scripts/start_application scripts/basic_health_check.sh prod.xml
    - aws s3 cp MyApplication.zip s3://prod-bins/
  only:
    - Development

我希望在stag构建结束后立即在指定的s3位置看到stag二进制文件。但是事实证明，只有在prod构建结束时才能看到stag二进制文件。 stag构建完成后，是否可以上传stag二进制文件，而无需等待prod构建完成？
