There is something strange going on with Jenkins plugin which gets versions from bintray. It shows mis-spelled versions. It was working fine till v6.1.1. Since version 6.1.2, DependencyCheck has moved from bintray to GitHub and because of that this Jenkins plugin in not usable anymore.  https://github.com/jeremylong/DependencyCheck/releases/tag/v6.1.2

Using any of them results in errors:
ERROR: Failed to download https://github.com/jeremylong/DependencyCheck/releases/download/version 6.1.4/dependency-check-ersion 6.1.4-release.zip from agent; will retry from master
