Alibaba Cloud DevOps:Use the needs syntax to control job dependencies

The YAML file of an Alibaba Cloud DevOps pipeline supports job dependency definition based on the stages.<stage_id>.jobs.<job_id>.needs syntax.

Typical scenario: app1 and app2 must be built and deployed together. The app1 build job depends on the completion of app1 unit testing and app1 code scanning jobs. The app2 build job depends on the completion of app2 unit testing and app2 code scanning jobs. To improve efficiency, app1 and app2 build jobs can be run concurrently. The deployment of app2 depends on the completion of app1 deployment.

The following figure provides an example of using YAML to build and deploy app1 and app2.
