Why not, but ideally if `--with-copyright-year` isn't specified at build time it should defaults to the year specified by the `SOURCE_DATE_EPOCH` environment variable (if specified). The idea is to have a single parameter, universal across projects, that automatically makes any build reproducible without further configuration. ------------- PR: https://git.openjdk.java.net/jdk/pull/1498
