Hopefully a 1000 projects don't need to be updated from Gradle 4 to Gradle 7!
Debian does not do out-of-git builds (.git directory is removed from
sources prior to build), thus I guess this plugin would not be of much
use (but I may be wrong).
Still required since it creates a BoofVersion.java file that's needed. If it can't find Git information it fills in that field with blank or unknown.
