@Gary it is the stage "you can do whatever you like on your side", even a
pom.properties flavor would work. I assume one of the most requested
feature will be to flatten attributes more than inlining them
("org.apache.foo:bar:1.2.3") but on the core side the challenge can be to
not break too fast all the "quick parsers" out there so likely staged for
v5 more than v4?Romain Manni-Bucau @rmannibucau <https://twitter.com/rmannibucau> | Blog <https://rmannibucau.metawerx.net/> | Old Blog <http://rmannibucau.wordpress.com> | Github <https://github.com/rmannibucau> | LinkedIn <https://www.linkedin.com/in/rmannibucau> | Book <https://www.packtpub.com/application-development/java-ee-8-high-performance> Le mar. 22 août 2023 à 14:58, Guillaume Nodet <gno...@apache.org> a écrit : > Not directly, but a simple extension could allow that... > > Le mar. 22 août 2023 à 12:33, Gary Gregory <garydgreg...@gmail.com> a > écrit : > > > Hi all, > > > > Would any of these changes allow me to write my POM's XML dependencies > in a > > single element where the GID, AID, and version are attributes (and not > > child elements)? > > > > <dependency groupId="org.apache..." artifactId="commons-io" > > version="2.13.0" ... /> > > > > In general, I want the XML to more OO, where XML elements are objects and > > attributes are, well, attributes. > > > > Gary > > > > On Tue, Aug 22, 2023, 3:36 AM Guillaume Nodet <gno...@apache.org> wrote: > > > > > Hi everyone, > > > > > > I hope you guys have been able to rest a bit during the summer (for > those > > > that are back to work already)... > > > > > > I've pushed a few important PRs in the past months and I'd really like > to > > > get the discussion going around those.
