Run the `./gradlew sanityCheck` task again to make sure there are no more errors.

#### Filtering changes by severity

There is a somewhat non-obvious filter present on the page that allows you to control which type of messages are displayed.
The filter is a dropdown box that appears when you click the `Severity ⬇️ ` label in the black header bar to the immediate right of the Gradle version.

 *
 * @param historyDays days number of days to store build history .
 * @param artifactsDays number of days to store artifacts. In the stored history, artifacts older than this number will be cleaned up.
 * @param artifactPatterns patterns for artifacts clean-up. If not specified, all artifacts will be removed.
