Thanks for your input Trent, I did have a look at the Nexus Unzip plugin previously, but I was hesitant as our Nexus is currently not at the minimum level required to use this plugin, so we would have to upgrade Nexus in order to try it
out. However, if we do exhaust other potential avenues, we can look into doing this.
I read on this wiki page that if you use "POM dependencies consider":
"Tycho then checks each of these artifacts, and if the artifact is an OSGi bundle,
it is added to the target platform."
https://wiki.eclipse.org/Tycho/Target_Platform#.22POM_dependencies_consider.22
This seems like it would be an ideal solution, to declare a dependency on a bundle artifact in the POM of a feature, except I think it's not working due to the limitation that we can't mix pom-first and manifest-first resolution in the same reactor?
https://wiki.eclipse.org/Tycho/How_Tos/Dependency_on_pom-first_artifacts#It_is_not_possible_to_mix_pom-first_and_manifest-first_projects_in_the_same_reactor_build
Any other ideas/options would be most welcome.
Cheers,
Irene

Hey Irene,
What our development team is doing to get the p2 repositories we want is the following :
- feature projects in which we group our plugin dependencies together in the feature.xml and list the dependency versions in the pom.xml for that project
- these feature projects are contained within a ‘parent’ aggregate maven project whose pom lists the tycho plugins and repositories to get our plugin dependencies
from
- we build all our features sequentially with the maven-invoker-plugin and run the package goal on them all
- after building the features, we run the package, then deploy goal on the update site project (which builds and deploys all the feature plugins
in a p2-style repository to our nexus box).
- an update-site project which builds as eclipse-repository and just points to the build state of all our feature projects (target/site folder)
- the update-site deploys to a regular Nexus maven repository, but we have the Tycho Nexus Unzip plugin pointing to a virtual repository which turns our deployed
maven artifacts (the update-site zip specifically) into an unzipped p2 repository that we’re consuming in targets and products.
Hope this information is helpful, keep in mind this is not exactly how tycho advocates this process, this is just what works best for us.

Hello,
We have some regularly changing external plugin dependencies that are deployed to a Nexus repository. As I understand it, in order for Tycho to be able to "see" and consume these bundles, we would need to first generate p2 metadata for them.
I am having some trouble figuring out the best workflow for systematically producing this p2 target platform, making it available for the upcoming Tycho build steps, as well as any subsequent local builds by developers.
I have considered using a separate Maven build to fetch the POM dependencies, generate the metadata, then redeploy a zipped p2 repository. However, I am not sure in which phase of my Tycho build, if such a possibility exists, I could fetch and "prepare" the
zipped repository (i.e. unzip) before Tycho does its dependency resolution.
Another possibility I have considered is having my official build create the p2 repository and keep the latest version somewhere accessible by HTTP on the same machine. This would avoid unnecessary uploading and downloading to and from Nexus, though we would
not have much versioning functionality then.
Is there a recommended solution for handling such cases where systematically processing external bundles is necessary?
Thank you very much in advance,
Irene
