All the methods are available via the changelog
extension and allow for reading the changelog file within the Gradle tasks to provide the latest (or specific) change notes.
Note
The following methods depend on the
changelog
extension set in the Configuration build phase. For safe access and process of your changelog file, we recommend accessing thechangelog
extension within Gradle closures as presented in the Usage section.
changelog.get(version: String): Changelog.Item
The method returns a Changelog.Item?
object for the specified version. Throws MissingVersionException
if the version is not available.
version
String
Change note version. changelog.getUnreleased(): Changelog.Item
The method returns a Changelog.Item
object for the unreleased version. Throws MissingVersionException
if the version is not available.
changelog.getLatest(): Changelog.Item
The method returns the latest released Changelog.Item

if the version is not available.
changelog.has(version: String): Boolean
The method checks if the given version exists in the changelog.
