Re: [tycho-user] Nexus-hosted p2 repositories
Hello,

To follow up, I learned something new about Maven today. :)

The key to my problem was that my changes were made in a "grandparent" POM. While some repository changes (commenting out other repos) took effect immediately by only reinstalling that grandparent POM, in order for the addition of my new Nexus p2 repository to be picked up, I had to also reinstall the parent POM of my eclipse-plugin project (i.e. the one that pointed to the grandparent POM). I'm not sure that I fully understand why I saw some differences immediately and not others, but in rebuilding all levels in the inheritance chain, my Nexus p2 repository works as expected.

Thanks,

Irene

Hi Jeff,

          

          Yes, I have <layout>p2</layout> in my
          <repository> declaration. I also had
          <releases><enabled>false</enabled></releases>
          and
          <snapshots><enabled>true</enabled></snapshots>,
          but just in case that made a difference, I tested without
          them. Unfortunately, that didn't change the results.

          

          Is there certain criteria that must be met for a repository to
          be included during Tycho dependence resolution?

Did you declare the repository with a p2 layout ?

Hello
              all,

              

              I've been very pleased with how the Nexus Unzip Plugin has
              been working out for sharing a p2 repository our PDE built
              dependencies. Once set up, the virtual repository URL
              works well for resolving Tycho dependencies.

              

              I would now like to use the Nexus P2 Repository Plugin to
              allow rebuilding individual Tycho-built plugins while
              resolving their dependencies from bundles previously
              deployed to Nexus through Tycho.

              

              However, I'm seeing some odd behaviour when I point to the
              <nexus>/<repo>/.meta/p2 repository URL, which
              does contain my artifacts in p2 repository format on the
              file system.

              

              When I include this repository in the eclipse-plugin's POM
              directly, I see what I would expect in the log:

              [DEBUG] Added p2 repository my_repo (http://<nexus>/<repo>/.meta/p2)

              

              However, when I add it to its ancestor POM this
              Nexus-hosted p2 repository is not listed as "added" in the
              log. The build then fails due to missing dependencies.
              Other non-Nexus-hosted p2 repository URLs are inherited
              fine from this (grand)parent POM, but this
              <repository> is ignored. I have also tried creating
              a p2 repository proxy that points to the .meta/p2 URL just
              to see if it would help, but the results are the same.

              

              Would anyone have an idea why this may be happening?

              

              Thanks a lot in advance,

              

              Irene

            "Legacy code" often differs from its suggested alternative
            by actually working and scaling.
