+                      Delombok only runs here: its sole consumer is the javadoc plugin below,
+                      which reads ${delombok.output.dir} so that the generated builders, getters
+                      and equals/hashCode show up in the javadoc jar. Running it on ordinary
+                      builds costs time and forces every contributor through
+                      lombok-maven-plugin, whose last release is 1.18.20.0 (April 2021) and
+                      which cannot delombok on newer JDKs.
