Custom Data in Build Scans

Gradle build scans support custom data in three forms: tags, links, and key-value pairs. Tags add contextual metadata (e.g., CI vs LOCAL), links attach URLs like GitHub commits or CI results, and custom values capture arbitrary build information such as branch names or build numbers. All three can be set programmatically in build scripts or passed via command-line system properties. When using Gradle Enterprise on-premises, build scans can be searched and filtered by this custom data, making it easier to diagnose build failures and share build context with teammates.
