In the global tools config, JENKINS_SERVER/manage/configureTools/ the latest version that it shows in the drop down for dependency-check is 11.1.0

I'm not sure if this started around the time that they moved from
https://github.com/jeremylong/DependencyCheck
to
https://github.com/dependency-check/DependencyCheck
and some config has to to be updated somewhere to track this change.
