Re: [eclipse-ide-wg] Minutes of May 3rd Eclipse IDE WG Steering Committee Meeting
|
Yes documentation is pretty rare, mostly because we are experimenting a
bit here and there probably and its a bit chicken-egg problem:
e.g. if no one uses the jetty-site (or do not report issues when trying
so and leave it alone) then we can't improve/find bugs what might lead
that people that are aware of it not considering it and so on.
But we are getting slowly some feedback on this (e.g. a user recently
reported the issue with PGP signatures and it got fixed hopefully now)
and even another project has started to consider those mvn-p2-sites and
gave some valuable feedback so things slowly evolve, but one can't
expect everything is working from day-1 like the "traditional" way that
is around for many years, so we all are still learning here.
I can only encourage everyone (if time allows) to just play around with
that stuff, report issues (also positive feedback is even welcome) or
suggest enhancements so I'm sure we will soon reach a stable-state here
that could be used by a wider audience (and we will then see more
examples, block-post, tutorials, ...)
e.g. one can join here:
https://github.com/eclipse/jetty.project/issues/8021
and try out the deployed snapshot that contains PGP signatures now (but
missing some bundles, so just focus on the PGP part) amd hopefully we
can fix more issues before the next jetty release so then there is an
even more valuable site available with just around a few kilobytes of
extra storage.

Instead of using (what only contains the subset relevant for Platform)
http://download.eclipse.org/releases/xxx
or even (what is outdated and no longer maintained)
https://download.eclipse.org/jetty/updates/jetty-bundles-9.x/
he would simply use
mvn:org.eclipse.jetty:jetty-p2:10.0.9:zip:p2site
If that information were available such that I might have found it, and
it actually worked at that time, that would have been useful. But
there was and pretty much still is a black hole in terms of
documentation about this. Also, please note that this was a time when
the platform was doing something to create jar-signed Jetty bundles
though only the subset that they needed, so this user was kind of stuck
(like what happened to WTP which also needed more bundles than the
platform and had to replicate what the platform did.
Anyway, it's water under the bridge.
from now on to get any jetty 10.x bundle pulled into his target that
is useful for their project. Of course it would still be possible to
consume some stuff from platform and the additional stuff from the
jetty-site.
and as platform already consumes the jetty-stuff from maven afaik he
will even get the *exact* same (and compatible) artifacts then by just
adjust the version a bit probably (have not checked what release
platform uses).
If there are still issues, he can report them to the jetty-team, wait
for the next release and gets an update soon, without any additional
steps required from platform, reficio, ... and the cycle begins again.

Christoph,
A reply that starts with "but" sounds like a contradiction is coming
right up. :-P *But *I think you are just agreeing that the primary
use case is in a target platform.
That being said, I'm not sure what exactly this "user/developer"
would do with such an update site:
https://www.eclipse.org/forums/index.php?t=msg&th=1110394
Likely he wants to include these additional things not provided/used
by Eclipse in his own update site.

Hi Ed,
but for what purpose? If I install the jetty bundles in my eclipse
simply nothing would happen ... I still would require additional
plugin to do something useful, configure the jetty-osgi and so on.
So most of the time I would have a project and that includes the
jetty bundles in their target, add some bundles, and features and
publish that as an update-site I could use to install some new cool
feature into my IDE.
And that's what this update-site is meant for. It enables consumers
of the jetty-bundles in the p2 eco-system to include them in their
builds/targets so it is not really an end-user thing I would send
over to a random user who asks for web-server support in eclipse IDE
:-)

Christoph,
Yes, I doubt many folks would install directly from such a site,
but many folks would use it in their target platform. After all,
what is the intended consumer of this Jetty p2 site if it's neither
of these?
There is often a tradeoff between the production side of things
where "no one really was interested in making such efforts" versus
the consumption side where the absence of such "saved" efforts is
disruptive and creates additional work for many people (and then in
total, there is more work). If only the many more people actually
contributed just one little iota towards the commons...

Hi Ed,
the jar URL is really not meant to be used here. For the mvn
protocol to work, m2e currently needs to be activated once, I'm
working hard to get away this limitation and thanks to the recent
changes in resources-plugin this hopefully will be fixed with the
next release.
For now, if you not try to add this page via "Update Sites" (I
assume no one really likes to install jetty *inside* eclipse) this
activation should happen as soon as you open the target editor and
hit the "Add" button (or earlier if you already has maven items in
your target).
I found the "eclipse forum" a really bad place to ask questions,
most of the time one don't get any response and I don't look at it
myself, so mailinglist and hopefully soon github discussions are
maybe more profitable to redirect users on the long term for such
questions.
Beside the jetty documentation, I think the best is to just open a
ticket at the jetty repo and then they can add a note.
As mentioned, there was an issue with PGP in a previous release so
pgp signing is disabled, but as this is fixed now the next release
will contain signatures again I already opened a ticket [1] and
encourage everyone to help testing so we can get this part working
without any additional effort in the future.
Her again, I think no one will install jetty "as-is" into a
running eclipse, so there is still the opportunity to sign the
used items in the site of the project as Mickael has described.
Sure one might want to create a mirror or similar, but jetty has
stopped publishing a site in the past because no one really was
interested in making such efforts, so I think the most
future-proof is to get this feature "smooth" (hint: test it / use
it / report problems) so we do no longer need to care about.

Christoph,
Previously I'd tried this approach:
jar:https://repo1.maven.org/maven2/org/eclipse/jetty/jetty-p2/11.0.9/jetty-p2-11.0.9-p2site.zip!/
That loads the content such that one can select it, but then
fails because of this

The mvn:org.eclipse.jetty:jetty-p2:11.0.9:zip:p2site URL fails
the same way although before loading. When I debugged I found
that the mvn protocol is only registered if the right bundle is
started, but that doesn't happen automatically; visiting the
Maven preferences helps.
In older versions I tested in the past, the PGP signatures were
rejected, but it seems this version doesn't have such signatures:
When a user asked about this on the newcomers forum, nobody had
an answer for them and when I went hunting, this site was not
helpful in discovering such an answer when I looked:
https://www.eclipse.org/jetty/download.php
It would be trivially easy to create a mirror that doesn't rely
on additional things being installed (and being activated in some
way)...

Just noticed the part about "a proper p2 repo for Jetty would be
nice"
There actually is already a p2 repository from jetty, you can
add the following URL to your target (requires m2e installed) as
an Update-Site:
Jetty 10:
mvn:org.eclipse.jetty:jetty-p2:10.0.9:zip:p2site
Jetty 11:
mvn:org.eclipse.jetty:jetty-p2:11.0.9:zip:p2site
See here for available versions:
https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-p2
This includes all jetty bundles and you can select the ones you
like. Next release of jetty will also contain PGP signatures
again (there was a bug in the previous Tycho release that is
fixed now).
