The most important part of this project is inside buildSrc directory - a Gradle plugin, which uses a containerized version of NVD database for Dependency Checking.
The main project is not that important at all. It just showcases that if you run
./gradlew build
OWASP Dependency Check is executed and produces correct results (in build/reports).
The National Vulnerability Database image can be built using a Gradle script from this repository.
