By default, SOOS enables the Scan Full Dependency Tree setting at the global level on the Configuration page. Users may opt to disable this setting globally or at the project level, based on their specific development needs.
When this setting is disabled SOOS will scan only top level dependencies declared in your manifest. The following notification will display on the Project Details page as a reminder.
If a full Dependency Tree scan is desired, click the link to the Configure page in the notification to update the settings. Once the settings are updated, initiate another scan to capture the full dependency tree.
Read here about the maximum allowable declared dependencies within the dependency tree.
