Alibaba Cloud DevOps:Control job dependencies with needs

In Alibaba Cloud DevOps, use the stages.<stage_id>.jobs.<job_id>.needs syntax in a pipeline YAML file to define job dependencies.

For example, suppose you need to build and deploy app1 and app2 together. The build job for app1 depends on both its unit testing and code scanning jobs, and so does app2. The build jobs for app1 and app2 can run in parallel, but the deployment of app2 depends on the app1 deployment.

The following YAML example shows this setup:

sources: 
  my_repo1:
    type: gitSample
    name: app1 code source
    endpoint: https://atomgit.com/flow-example/spring-boot.git
    branch: master
  my_repo2:
    type: gitSample
    name: app2 code source
    endpoint: https://atomgit.com/flow-example/node-expressjs.git
    branch: master
defaultWorkspace: my_repo1
stages:
  build_stage:
    name: Build
    jobs:
      test_job1:
        name: app1 unit testing
        steps:
          command_step:
            name: Execute Command
            step: Command
            with:
              run: |
                echo This is build job...
      scan_job1:
        name: app1 code scanning
        steps:
          command_step:
            name: Execute Command
            step: Command
            with:
              run: |
                echo This is build job...
      test_job2:
        name: app2 unit testing
        steps:
          command_step:
            name: Execute Command

                echo This is build job...
      scan_job2:
        name: app2 code scanning
        steps:
          command_step:

            step: Command

      build_job1:
        name: app1 build
        # This job depends on test_job1 and scan_job1.
        needs: 
          - test_job1
          - scan_job1

            step: Command
            with:
              run: |
                echo This is build job...
      build_job2:
