What situations can trigger automatic build in a continuous integration pipeline?

Automated build in a continuous integration (CI) pipeline can be triggered in the following situations:

• When committing or pushing changes to the version control system (e.g., Git).
• When creating a pull request or merge request.
• On a schedule (e.g., nightly builds).
• When changing the project's configuration or dependencies.
• Manually, upon developer request.

This allows for quick code quality checks, running tests, and early detection of errors during development.
