Hi all,
A few days ago, Matthias started a thread [1] to identify what needs to
be done before we could release Maven 4.0.0. He explicitly asked not to
reopen previous discussions in that thread - that's why I'm opening a
new one.
In that thread was a reply from Elliotte where he raised his concerns on
a couple of issues in the current codebase. I will try to summarise:
1. Maven 4.0.0 should not come with an XML namespace change.
2. We cannot introduce "experimental" API's; similarly, we can't
"deprecate" API's without proper documentation about their replacement.
3. Unnecessary complication in basic functionality.
Elliotte, please feel free to elaborate and/or refer back to earlier
mailing list threads where those things have been raised.
The thing I would like to discuss in this thread: **do we feel
comfortable releasing Maven 4.0.0 in this state?**
My personal opinion on the above three points:
1. I do not have enough knowledge to judge on this. When in doubt, do
not proceed - I would like to hear the experts voices on this before
deciding to cut a release.
2. I very much agree here. If we can't even say that usage of the
(deprecated) method-X now needs to call the (new) method-Y, then who
can? We owe it to people building on top of Maven to provide them with
guidance. Also, releasing "experimental" API's is not a sign of "yes,
this is an improvement of what we had and you should all use this". It's
been around for well over a year in various beta and RC releases, I
think we need to decide if we keep them or remove them.
3. This personally worries me the least, *as long as those interfaces
are not part of our public API/SPI*. If they are only internal, we could
safely remove them and simplify in 4.0.x or 4.x.y. If those interfaces
are for public consumption, then we might want to reconsider if they
could become non-public.
Curious to hear your thoughts on this. As much as I would love to see
Maven 4 go public, I *don't* want to ship software we know is in a
broken state.
Thanks,
Maarten
