Description: The build number is a unique identifier assigned to each execution of a build process within a continuous integration pipeline. This number allows developers and software teams to track and manage different versions of their code as changes are made and new builds are generated. Each time a change is made to the code repository, the continuous integration system automatically generates a new build number, which can be a sequential number or an identifier based on the date and time. This identifier is crucial for traceability, as it enables teams to quickly identify which version of the code is being used in a specific environment, facilitating debugging and problem analysis. Additionally, the build number may include additional information, such as the build status (successful, failed, etc.), providing valuable context for developers. In summary, the build number is an essential tool in agile development and DevOps, as it promotes transparency and efficiency in the software development lifecycle.
