#9258 — Need for help: Eclipse Neon

[Multipart message — attachments visible in raw view] — view raw

Dear Java Team,
I am trying to build a recent version of Eclipse.

Eclipse requires Tycho Maven Plugin to build, and I have packaged it
using suggestions from Fedora packagers:
https://mentors.debian.net/package/tycho
(currently, we don't use Fedora scripts to build Tycho, we just use
patches, maven, and maven-repo-helper)

Then, I have tried to build Eclipse.
I have uploaded my trials here:

https://anonscm.debian.org/cgit/pkg-java/eclipse.git/tree/debian?h=experimental

During the build, Tycho fails with tons of errors. They are attached.
Can anyone try to help me?

As a minor issue, Tycho requires a recent version of sat4j. I have
packaged it here:
https://mentors.debian.net/package/sat4j
I have already tried to contact the maintainer, however I didn't get any
feedback.

Regards.

Luca

Well done! I think you can push the packaging repository to alioth now.
I see some potential minor improvements, we can help you.

I see two issues:
- something that looks like a tycho error. Did you try switching the
tycho jar you built with the official one? Maybe you forgot something in
the tycho package (some classes or resource files).
- org.eclipse.osgi.storagemanager.ManagedOutputStream is not found. This
class comes from eclipse, maybe the modules aren't compiled in the right
order?

I think we should ask Michael Tautschnig to move the package under the
pkg-java umbrella so it can be team maintained. sat4j is only used by
eclipse so that would make sense.

Thank you Emmanuel.

I'm sorry for the delay, I'm not at home this month.

That's ok. I suppose I cannot create a repository in Alioth, somebody
should create it for me, am I right? Something like
https://git.debian.org/git/pkg-java/tycho.git ?

Yes, and no. This package creates 15-20 jars... I have tried to replace
some of them, however these jars are not "patched", so I get many more
errors.

That class exists. It is in the org.eclipse.osgi jar. I cannot
understand why it is not found at runtime.

#9810

My line of enquiry has been to look at what's happening in
eclipse-bundles/org.eclipse.osgi/container/src/org/eclipse/core/runtime/adaptor/EclipseStarter.java.

In the startup function,
context.getServiceReference(FrameworkLog.class); and
context.getServiceReference(EnvironmentInfo.class) are returning null.
context is a BundleContext
(eclipse-bundles/org.eclipse.osgi/osgi/src/org/osgi/framework/BundleContext.java)
object.

So I conclude that FrameworkLog and EnvironmentInfo are service
objects which haven't been registered with the Framework service
registry. The question is, what needs to be in place for them to be
registered?

My current hunch is that we might need to add
org.eclipse.osgi.services_3.5.0.v20150714-1510.jar to
tycho-bundles-external-0.25.0.zip to provide EnvironmentInfo.

I've spent the whole day looking at tycho and am going to have to put
it to one side for the time being.

I'm not clear what, if any, relevance
tycho-bundles-external-0.25.0.zip has to the build?

My guess is that in order to build eclipse, various OSGi bundles like
org.eclipse.osgi.services need to be pulled in from a P2 repository,
but it's beyond my current level of understanding to see how to do
this. (I'm not a Java programmer - and I've no prior knowledge of
OSGi).

Perhaps someone more experienced in this area might be able to take a look?

Hi,

updating Eclipse to the latest version is a non-trivial task and
requires a lot of time and research. I have also tried it but I never
got to the point where I felt comfortable with the result. That doesn't
mean I have given up yet but it requires some dedicated effort. In
short: I can't help you at the moment but if you are able to reproduce
Fedora's packaging of Eclipse, then you are one step closer to the final
result.

Regards,

Markus
