I wonder if no one has the need for hosted P2 repositories? Nexus
Professional only provides P2 Mirrors (proxies) and P2 groups - but no
P2 repo where one can upload P2 artifacts. Virtual P2 repos (P2 view on
top of a Maven repo) aren't supported either.
Our products depend on various projects built in our company. Until now
we had a non-p2-target platform which was checked into SCM and we could
maintain it by hand. We used the tycho.targetPlatform option in our
tycho build. This seems to be obsolete and we should move our target
platform to a p2 repository manager. But I cannot find one.
Is it the only solution to create a p2 repository with the eclipse p2
tools and upload it to a webserver? This looks quite unreliable when
several builds have to push their bundles to this repository.
How do you work with third party bundles which aren't contained in the
Helios / Orbit repositories?
We have a few implementations of p2 hosted repositories but nothing we're ready to share.
We are looking into sharing our implementations with a few people who are interested, but there's a lot of work to do here.
If you're interested you can ping me offline.

I'd like to know why tycho deploys p2 meta data to a maven repository
(p2artifacts.xml/p2content.xml). Who is currently able to use this data?
Is tycho able to access bundles out of a remote maven repository? Or can
it do so for local maven repos only? I've discovered that tycho projects
can depend on bundles from my ~/.m2/repository - but not from remote
maven repos (this would be really cool: we would not need hosted p2
repos anymore).

The OSS version of Tycho does not deploy to repositories. Only the SimpleRepository implementation of p2 can read that metadata. The artifact and metadata model is decoupled in Tycho so we made a new repository implementation that allows incremental deployment of artifacts in much the way you would expect with Maven. Eclipse and p2 were just not initially designed to do this. It was designed to drop released versions in mostly static repositories.

Sort of. If you put dependencies in your POM which are, in fact, bundles and turn on the option to look for bundle in the local maven repository it will work.
So basically you use Maven's downloading capabilities to put the bundles in the local Maven repo and then Tycho will find them there. What we typically do is let Nexus generate the p2 metadata on a Maven repository of bundles and then Tycho works fine.

You are never dedicated to something you have complete confidence in. No one is fanatically shouting that the sun is going to rise tomorrow. They know it is going to rise tomorrow. When people are fanatically dedicated to political or religious faiths or any other kind of dogmas or goals, it's always because these dogmas or goals are in doubt.

Can this feature (generation of p2 metadata) be used with Nexus OSS?
No, it's currently being developed as a commercial feature.
Kind regards, Lars

These are useful in local repository only. We tried to use them in
remote repositories, but ran into problem described in
