Looks like imglib2-clearvolume has a working pom, courtesy of @ctrueden.
I was able to get an example project compiling, though the examples don't seem to show anything. Perhaps it is a driver issue (testing on Windows 10, nvidia drivers and cuda have been installed and updated)
I fully understand things are in flux, and will be smoother soon. Hopefully the hacking group I was talking to, gains an interest in ImageJ and ClearVolume, and checks back to see updates and progress. If anyone has any suggestions for the following issues let me know...
a) Running testOpenClearVolumeOnToyVolume gives
but then lClearVolumeRenderer.isShowing() is false, and the program ends.
b) Running testImageJClearVolumePlugin gives
