Description: The ‘Pre-build Action’ in continuous integration systems refers to a set of tasks that can be executed before the build process of a project begins. These actions are crucial for preparing the build environment, ensuring that all necessary dependencies and configurations are in place. For example, code checks can be performed, required libraries can be downloaded, or environment variables can be configured. The importance of these actions lies in their ability to detect and resolve potential issues before the build starts, which can save time and resources. Additionally, by automating these tasks, the efficiency of the development workflow is improved, allowing teams to focus on coding and implementing new features. In summary, ‘Pre-build Actions’ are an essential component of continuous integration and agile development, contributing to a smoother and less error-prone development process.
