Plugins IU directly in category.xml [message #868734]

Hi all,

I want to put directly plugins in my category.xml (I don't want to use
features for those plugins, that I don't own, I just want to mirror
them, they are available in Orbit without feature).
I know p2 can publish directly plugins. I noticed category.xml editor
does not provide entry for Plugins,

So, simple question:
Is there a way (independently of category editor) to add plugins in
category.xml ?
The goal, ultimately, would be to support it also in Tycho.

Thanks in advance.
Mickael

Have you looked at the category.xml we use in Orbit? It's possible to
define categories using queries.

http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.orbit/org.eclipse.orbit.releng/maps/category.xml?view=markup&revision=1.5&root=Tools_Project

I think it's also possible to list units directly. But I'm not sure
if/where it's documented properly. I discovered the query feature by
looking at the source code.

I did have a look at it. But queries are too complex for my use-case.

Will have a look at source then.

I found the UI part in org.eclipse.pde.internal.core.idite, but nothing
related to Queries or bundles as IU.
Which class gave you hints for queries?

Found org.eclipse.equinox.internal.p2.updatesite package.

The <iu id="bundle.name"> element looks promising, but it looks like
CategoryPublisher application only works on existing repository and is
only good at organizing an already existing repo.
What I want is to create a repo and publish some plugins in it, without
making them part of a feature.

But I also found that Tycho seems to use its own implementation, based
on ContextValue "TychoConstants.CTX_PUBLISHED_ROOT_IUS", use by
AssembleRepositoryMojo, to invoke MirrorAppicaiton and
MirrorApplicationServiceImpl....

Both Headless command and Tycho Mojo rely on the CategoryXMLAction and
SiteXMLAction for that. SiteXMLAction seems to perform some cool stuff
for <iu> but I can't get it to work.
Any help on its usage would be very welcome.

If I understand correctly, <iu> are more aimed to categorize stuff that
is already part of the site. So not good for my use-case.

Then I opened this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=378338

Hi Mickael,

That's how it works. The p2 category Ant task (and application) takes
any existing p2 repository and adds categories to it (depending on a
given category.xml).

So you don't need categories for this. You can simply mirror or publish
any plug-in to any repository. Features are really just a way to group
bundles. My understanding was that you wanted to have categories as a
way to use "groups" of bundles in a Target Platform (or so).

But there is no way to do it by editing a category.xml file, isn't
there? I'll need to use p2 tasks or scripts (which I tried to avoid as
much as possible in our Tycho-based build process).

Sorry if I was not clear. What I want is to give a category.xml
containing a bundle that is not part of a feature to Tycho and get as
result a repository which contain the IU for this bundle.

I'm not sure category.xml is the right thing for this job. From my
understanding, category.xml is only used to modify repo meta data. None
of the existing scripts/tasks use it for publishing bundles into a repo.

A Google search brought up this for publish bundles in Tycho:
https://docs.sonatype.org/display/TYCHO/Tycho-extras+-+FeaturesAndBundlesPublisher

There is also some discussion here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=347303

Have you tried this?
