Duplicate BOM Detection

To improve scan performance, the duplicate BOM detection feature is enabled by default.

If the feature determines that a scan will produce a BOM identical to the existing one, it skips the BOM computation. You can disable it by using the following setting:

SCAN_SERVICE_OPTS=-Dblackduck.scan.disableRedundantScans=true

You can change this setting in the blackduck-config.env file.

Note: In Black Duck 2021.4.0, this feature only impacts package manager (dependency) scans when the set of dependencies discovered by Detect is identical to the set from the previous scan. This capability will be extended in future releases.
