dependency-check-ant is an Ant Task that uses dependency-check-core to detect publicly disclosed vulnerabilities associated with the project's dependencies. The task will generate a report listing the dependency, any identified Common Platform Enumeration (CPE) identifiers, and the associated Common Vulnerability and Exposure (CVE) entries.
