                     This declaration merges with the one in the parent, rather
                     than overriding it, so we need to disable the "validate" phase
                     execution that the parent declares and declare our own
                     during "test-compile".

                     One reason for this is that avro codegen runs during compile,
                     and while it's not strictly a precondition, it's
                     confusing to address style violations while the IDE is telling you
                     that some generated class doesn't exist. Test-compile is the first phase
                     that's guaranteed to run after compile and before any unit or integration
                     tests.

                     Also, we want to disable the parent's configuration because it declares stuff
                     we don't care about, like suppressions. (Honestly, it shouldn't)
