Due to not observing much activity from the original author on github account and having project needing to make use of this version immediately.

The 2.1.0-SNAPSHOT this is marked up as is available to use directly from the source github/dlmiles account, if you follow the README information there.

This information is present in these change set so will require a little more work to hide/remove before the next official release is made.

All patches should hopefully be well separated and changes documented, each has been individually compiled successfully under CI to validate with Java8 and Java11 and the range of Gradle IT version tests between 5.6 and 8.0.2.

Sorry did not intend to closed. But now it has occurred.

I will reopen against a non-master branch from my repo (to disconnect and free up dlmiles:master from this PR) did not expect PR to be open this long.

GHA requires some aspects of .github/workflow to be in the default branch. So while I work on some GHA CI to help maintenance.
