“.gitlab-ci.yml” pipeline returns 错误“找不到下游项目”

Question

所有项目的路径均有效。我可以确认这一点，因为下面的代码可以运行并运行一个子管道：

  stage: multi_project_test
  trigger:
    project: "my_organization/my_group/project_1"
    strategy: depend

但是下面的代码导致 downstream project could not be found:

stages:
  - test
  - multi_project_test
  - deploy


include:
  - local: ".gitlab-ci-common.yml"

test:
  extends: .test_stage_common
  script:
    - poetry install -vv
    - !reference [.test_stage_common, script]

downstream_pipelines:
  stage: multi_project_test
  parallel:
    matrix:
      - DOWNSTREAM_PROJECT:
          [
            my_organization/my_group/project_1,
            my_organization/my_group/project_2,
            my_organization/my_group/project_3,
            my_organization/my_group/project_4,
          ]
  trigger:
    project: $DOWNSTREAM_PROJECT
    strategy: depend
  variables:
    PIPELINE_TYPE: "multi-project-pipeline"

为什么会出现错误？

Answer 1

很多地方允许使用变量，但是trigger:project不支持使用变量。有一个 open issue 跟踪使此功能适用于 trigger:project。

从 GitLab 15.0 开始，可以在 .gitlab-ci.yml 中的以下位置使用变量：

Definition	Can be expanded?	Expansion place
`after_script`	yes	Script execution shell
`artifacts:name`	yes	Runner
`before_script`	yes	Script execution shell
`cache:key`	yes	Runner
`environment:name`	yes	GitLab
`environment:url`	yes	GitLab
`except:variables:[]`	no	n/a
`image`	yes	Runner
`include`	yes	GitLab
`only:variables:[]`	no	n/a
`resource_group`	yes	GitLab
`rules:if`	no	n/a
`script`	yes	Script execution shell
`services:[]:name`	yes	Runner
`services:[]`	yes	Runner
`tags`	yes	GitLab
`variables`	yes	GitLab/Runner

有关完整参考，包括可以使用的其他 files/places 变量，请参阅文档：where variables can be used。

作为解决方法，您可以改为在 script: 中触发项目，should provide the same effect.

trigger:
  image: alpine
  parallel:
    matrix:
      - DOWNSTREAM_PROJECT_ID: ["1234", "5678"]
  script:
    - apk add --no-cache curl
    - curl --request POST --form "token=$CI_JOB_TOKEN" --form ref=main "https://${CI_SERVER_HOST}/api/v4/projects/${DOWNSTREAM_PROJECT_ID}/trigger/pipeline"

“.gitlab-ci.yml” pipeline returns 错误“找不到下游项目”

".gitlab-ci.yml" pipeline returns an error `downstream project could not be found`
