Re: [jbosstools-dev] Why does update/kepler now point to Alpha2 ?

Then we should coordinate the changes better. Your addition of Jetty

Had they all happened the same day, then yes, they would have all been
part of Alpha2.
But because there was a chance someone was using Alpha2 with the new
Jetty with Kepler M5, I didn't want to break them by suddenly changing
the underlying baseline.
The last time we had a workflow where contents of the target platform
could change "at random", to use Max's favourite phrase, Max
complained every time.
In my understanding SNAPSHOT means "Work in
Progress/nothing guaranteed"
and includes that it can change more or less "at random". So we can make
incremental changes on the target-platform.
But that's only my understanding, maybe in our context it means
something different.
If we keep my definition of SNAPSHOT, the fact that Alpha2 has not been
released means that we are free to change it.
The general idea of a SNAPSHOT is that we won't be able to make the
target-platform at first shot, it gives us the right to make mistakes
that we can fix easily (by fixing and respinning this snapshot) and to
make incremental changes, which will make the team happy as different
requests for TP change happen multiple times during a dev stream.
Now, I version them explicitly so that every substantial commit is a
new version... and ya'll complain about that too.
It's better ;) But
I'm wondering about the usefulness of moving to
Alpha3-SNAPSHOT when there is still an Alpha2 pending.
In the grand scheme of things, wouldn't you rather have snapshots
you
can ignore (Alpha2, than snapshots that no longer exist because they
were overwritten?
What is the benefit? This is going to lead us to have one version
for
each TP revision. We already have revisions to track atomic changes, I'm
not sure we need something as fine-grained for public Maven versuins.
Also, your proposal about more TP versions (with some ignored) will
imply more maintenance effort to switch from a TP to another. We (ie you
and me) won't like it.
IMHO it's *more confusing* if you're building one day with
Alpha2 and
it works (because Kepler M5) and the next day it stops working
(because Kepler M6), than if you discover an email saying "want to use
Kepler M6? Grab the Alpha3 version of the target platform."
If you're
using one day Alpha2*-SNAPSHOT* and it works means that there
will be some changes that may break you. So we make master use SNAPSHOT,
and make changes on SNAPSHOT, and if we do something wrong, people will
see it, us included.
