Describe the bug
After upgrade from Dependency Check 8.2.1 to 9.0.10 the build of a project with multiple subprojects that use Dependency Check the build pipeline fails with the error below. Downgrade back to 8.2.1 does not work due to NVD API changes.

Version of dependency-check used
The problem occurs using version 9.0.10 of the Gradle plugin.
