Update on Maven declarative builds: A new, hopefully readable syntax has been implemented. I think I addressed most of the issues identified by early adopters. Thanks again for providing valuable feedback!
You can the new syntax it in action at the plexus-cipher spec file at https://src.fedoraproject.org/rpms/plexus-cipher/blob/rawhide/f/plexus-cipher.spec Upstream documentation for the syntax is available at https://github.com/mizdebsk/dola/blob/master/MANUAL.md -- Mikolaj Izdebski On Fri, Jun 13, 2025 at 6:21 PM Mikolaj Izdebski <mizde...@redhat.com> wrote: > > Hi all, > > I'm excited to announce the preview availability of declarative Maven > RPM builds in Fedora 43 -- a new approach to RPM packaging for > Maven-based Java projects that focuses on simplicity, consistency, and > future automation.
