trigger a build on a project when a commit pushes to another project

问题

I have three projects A,B,C on gitlab with a gitlab-runner machine. Project A contains gitlab-ci.yml file which calls a script to build the program when there is a commit on A:

  build:
  stage: build
  script:
    - ./build-platform.sh

A depends on B and C projects. How can I trigger a build on A when there is a commit on B or C. I cannot put B,C in A and I cannot convert build-platform.sh to a gitlab-ci.yml file syntax easily.

There's a couple ways of doing what you want, but they all rely on you going to project A's settings in gitlab and adding a trigger token. This is done through the <project A's gitlab URL>/settings/ci_cd page by clicking on Add trigger in the Triggers section.

You will also find the different ways of using that trigger token from that page.

For the sake of completeness here's a few of the ways mentioned there:

1 Using cURL

If you can use curl at the end of the build of projects B or C then simply add the following:

curl -X POST \
     -F token=TOKEN \
     -F ref=REF_NAME \
     <gitlab_url>/api/v3/projects/1/trigger/builds

Where TOKEN is the trigger token you just generated for project A and REF_NAME is the name of a branch or tag to run the build for.

This can be done if you have automatic builds for projects B and C (using a .gitlab-ci.yml file for instance).

2 Using a webhook

You can add a webhook to projects B and C through the settings/integrations page of those projects.

Simply add the following webhook on push events:

<gitlab_url>/api/v3/projects/1/ref/REF_NAME/trigger/builds?token=TOKEN

Where TOKEN and REF_NAME are the same as above.
