            Since the NVD database is pretty large, you should consider storing it in some persistent location to reuse

            such as ~/.cache/ant/owasp/database for Linux or ~/Library/Caches/Ant/owasp/database for MacOS.
            Putting that property into your ~/.ant/build.properties file is recommended.

            failBuildOnCVSS is by default 11 so build would never fail,
            the table categorising vulnerabilities is here (1), so by setting
            "failBuildOnCVSS" to 1, we will fail the build on any CVE found
            if it is not suppressed already dependency-check-suppressions.xml

            If a vendor provides no details about a vulnerability,
            NVD will score that vulnerability as 10.0 (the highest rating translating to critical).
