[gentoo-java] Eclipse Libraries

Hey,

as already said in my previous mail, I am currently packaging software
which depends on some eclipse libraries.

The first ebuild which needs them is dev-java/jameica [1].

It's distribution includes the following jars:

* org.eclipse.core.runtime_3.1.1.jar
* org.eclipse.jface_3.1.1.jar
* org.eclipse.osgi_3.1.1.jar
* org.eclipse.ui.forms_3.1.0.jar

which I found in the java-experimental overlay.

First problem I encountered was that some of the transitive
dependencies, namely

* dev-java/eclipse-ui-workbench-3.2.2.ebuild
* dev-java/eclipse-help-3.2.2.ebuild

depend on a non-existant version of icu4j (=dev-java/icu4j-3.4*).

I tried to remove the exact version-dependency and ran into the next
problem,

http://download.eclipse.org/eclipse/downloads/drops/R-3.3.2-200802211800/eclipse-RCP-SDK-3.3.2-linux-gtk-x86_64.tar.gz

cannot be found because it move to the archive:

http://archive.eclipse.org/eclipse/downloads/drops/R-3.3.2-200802211800/eclipse-RCP-SDK-3.3.2-linux-gtk-x86_64.tar.gz

I changed the URI in the eclass, but then Portage tells me, that the
filesize of the downloaded package does not match the recorded size. Weird..

The ebuild for the actually application I want to package - hibiscus [2]
- - furthermore depends on Eclipse BIRT [3], the "Business Intelligence
and Reporting Tools", for which I was not able to find an
ebuild yet. Is there any work going on?

Kind Regards,
Fabian

Once I tried building RCP part of eclipse standalone but gave up
because they were too highly coupled and I didn't manage to get a
working dependency order. Since then upstream started providing build
tools for Eclipse. I don't know if it allows building a stand-alone
RCP or parts of it.

If you try to continue the work, I'd love to share my experience (as
far as I remember since it's been a long time)

Serkan

I also had a shot at building Eclipse plugins quite some time ago. I
was focusing on third party plugins rather than the core Eclipse
components but there is some overlap there. Ideally they should be
built using the Eclipse PDE but last time I tried, unbundling the JARs
was still a nightmare. I believe the tools Serkhan mentioned are
supposed to improve this situation but I've stopped using Eclipse since
then. For a while now, we are supposed to have been using the P2 system
for handling the plugins but due to a silly bug that's never been
fixed, Gentoo still isn't using it.
