@chrisdennis @alexander-komarov-ibm : still some infra (I think) issues, even when rebase on top of Chris build adjustmnents.

See: https://dev.azure.com/TerracottaCI/ehcache/_build/results?buildId=13532&view=logs&j=977408ae-2229-5105-76ed-da164cbe8f87&t=9c6eaf4c-503b-5791-4b0b-68ad9fb31444&l=34

A problem occurred configuring root project 's'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve org.owasp:dependency-check-gradle:12.2.0.
