Al,
I did think of asking webmaster if the repos are
backed up and if so, to restore the 0.4 artefacts.
(The bug number is https://bugs.eclipse.org/bugs/show_bug.cgi?id=452142)
But if you can rebuild the 0.4 release before then,
that would be great. I guess at least we know now
that some projects are relying on 0.4.
If we do this, I would like to have some sort of red
flags all over the place to point people to the newer
versions to minimize the chances of new
implementations using 0.4.
(On a separate, slightly unrelated note, I don't
understand why our Java release job should deploy a
half-complete project if the build fails. We must
change it so that only a complete project is deployed.
The most obvious way is to have a separate deploy
job, using artefacts from a previously successful
build (see https://wiki.eclipse.org/Services/Nexus#Hudson_Job_Setup).
I would like you or Bin to look into this while I'm
away - thanks.)

Ian,
It should be possible to recreate the 0.4.0 release,
it was tagged I'll see if hudson can do a build
based on tags, if not creating a new git branch for
the code would let us build it again, I'll take a
look when I get in to the office this morning,
unless you've already handled it.

Hi,
the 0.4 build was not an official Eclipse release,
unlike 0.9 and
later. I was not leading the Paho project when
the 0.4 build was put
into the repository. But the main problem with
0.4 was that the
repository structure changed for 0.9 and later,
which meant that people
were discovering the 0.4 build and thinking it was
the current and only
release.
I have no intention of removing the 0.9 or later
artifacts - as they are
official releases, and they all conform to the
current repository
structure which means that you can see all the
versions available, and
choose from them.
Even if I did get the 0.4 artifacts restored (and
I'm not sure I can do
it at this point), I would prefer to have them in
the updated repository
structure so that it was obvious that there were
later versions. But I
expect that is not what you're asking for?

Hi mqtt devs,
This is a very serious issue for the Spark
project because a lot of
Spark users build from source. We are going to
upgrade mqtt version
for future releases, but this breaks all
current/past releases. In
case you are not familiar with Spark, it is now
the most actively
developed Big Data open source project: in the
past year alone, there
are close to 400 people that have contributed
code to the project.
Many applications are being built on top of this
and this can
potentially break all of them. I'd also imagine
this breaks other
non-Spark projects that depend on mqtt as well.
A released artifact in a repository should be
immutable. Spark depends
on it, other applications depend on it, and
applications that depend
on Spark can depend on it. The transitive
closure is pretty large.
Again, we are going to upgrade the mqtt
dependency in Spark, but I
urge you to add the 0.4.0 artifact back.
Otherwise we would have to be
extra cautious in the future with respect to any
dependency on mqtt,
e.g. removing it from the dependency or the
default build profile,
which would cause inconvenience for our users
also.

Hi All,
I agree with Brian. Of course work with
lastest version is best
way, however it could break some legacy code
where you can't
change fast for any reasons (who works for
Enterprise companies
knows this bad situation).
IMHO, remove the old version from Repository
maybe is not the best
approach to improve the innovation. The idea
in general is good
but maybe we could find another way.
Best,

I've been talking with Reynold from the
Spark team (copied)
about the possibility of updating to a
newer version. In
addition I really think we should restore
that old build to
keep existing builds working.

Brian,
that approach sounds like exactly what
we have now, and which
I was hoping to avoid. In addition to
other factors, the 0.4
version was not an official release.
I'm trying to get a 1.0.1 service
release out (while on
vacation), so I'm having to get a crash
course in
Maven/Nexus. Maybe I'll figure out a
better or correct way
to move people onto the later versions.
Can't we get Apache Spark to update
their dependency?

Ian,
I agree on the issues around
supporting those older versions.
In our case we are doing a build
which relies on another
project (Apache Spark) which is
explicitly building with
that older version of the mqtt-client
(https://github.com/apache/spark/blob/master/external/mqtt/pom.xml#L44-L48).
Removing the 0.4.0 artifacts means
that builds expecting a
specific version (even if older, not
the latest, etc.) will
break.
My suggestion would be to restore the
older builds, then
if/when users encounter or report
bugs, have the first
response be "first, upgrade to the
latest".

Brian,
apologies, but we have kept
getting questions and bug
reports about the older versions
of the Java client. It
seemed that the repo structure
had led people to find
the 0.4 version sometimes in
preference to the 1.0
version or later. I thought that
deleting the 0.4
version would help minimize
people encountering bugs
which had already been fixed -
which is a waste of
everyone's time, user and
developer.
If anyone has any other
suggestions for how we should
manage this, I would be happy to
hear them.

We recently noticed a
working build which started
having a problem pulling in
the .jar files for
mqtt-client v0.4.0.
It looks like this repo dir
is empty:
_https://repo.eclipse.org/content/repositories/paho-releases/org/eclipse/paho/mqtt-client/0.4.0/_
If I go up one level, it
shows the 0.4.0 dir as
last modified on Wed Nov 19
09:46:54 EST 2014.
Is it possible that the
files were removed
accidentally, or are we
pointing to the wrong place?
thanks,
Brian
