GitLab CI如何确保后续任务仅在前序关联任务执行后运行？

我配置了包含build和deploy两个阶段的GitLab CI流水线，build阶段的Build0、Build1任务各自带有运行规则，仅满足条件时才执行。现在希望deploy阶段的Deploy0、Deploy1任务仅在其关联的Build0、Build1任务已执行时才运行，且不想复用build阶段的规则以避免冲突，请问是否有可行方案？

原流水线配置如下：

stages:
  - build
  - deploy

Build0:
    stage: build
    extends:
        - .Build0Rules
        - .Build0Make

Build1:
    stage: build
    extends:
        - .Build1Rules
        - .Build1Make

Deploy0:
    stage: deploy
    dependencies:
        - Build0
    script:
        - bash gitlab-ci/deploy0.sh

Deploy1:
    stage: deploy
    dependencies:
        - Build1
    script:
        - bash gitlab-ci/deploy1.sh

可行方案 #

无需复用build阶段的规则，有两种可靠方案实现需求：

方案一：通过needs关联+任务状态规则 #

给每个Deploy任务添加needs关联对应的Build任务，同时用规则限定仅当关联Build任务成功时才执行：

Deploy0:
    stage: deploy
    needs: ["Build0"]
    rules:
        - if: '$CI_JOB_STATUS == "success"'
          when: on_success
    script:
        - bash gitlab-ci/deploy0.sh

Deploy1:
    stage: deploy
    needs: ["Build1"]
    rules:
        - if: '$CI_JOB_STATUS == "success"'
          when: on_success
    script:
        - bash gitlab-ci/deploy1.sh

• 若对应的Build任务未触发（不满足自身规则），Deploy任务会因needs指向的任务不存在而自动跳过
• 若Build任务执行失败，Deploy任务也不会启动

方案二：变量标记触发 #

在每个Build任务中设置专属变量标记任务已执行，Deploy任务通过规则判断该变量是否存在：

Build0:
    stage: build
    extends:
        - .Build0Rules
        - .Build0Make
    variables:
        BUILD0_EXECUTED: "true"

Build1:
    stage: build
    extends:
        - .Build1Rules
        - .Build1Make
    variables:
        BUILD1_EXECUTED: "true"

Deploy0:
    stage: deploy
    dependencies:
        - Build0
    rules:
        - if: '$BUILD0_EXECUTED == "true"'
    script:
        - bash gitlab-ci/deploy0.sh

Deploy1:
    stage: deploy
    dependencies:
        - Build1
    rules:
        - if: '$BUILD1_EXECUTED == "true"'
    script:
        - bash gitlab-ci/deploy1.sh

这种方式完全独立于build阶段的原有规则，通过变量标记明确控制Deploy任务的触发逻辑，不会产生规则冲突。
