Gemini DBAccess Maven Artifacts [message #932596]

Thu, 04 October 2012 08:54

Eclipse User

I am unable to find any maven-artifacts for Gemini DBAccess. Are there any? If so, where can I find them? If not, is there a specific reason?

Regards,

Björn Pollex

Hi Björn,
you are right, there are no maven artifacts for DBAccess. Unilt now, no-one has been asking for them. Please open a bug with the feature request for tracking [1].

There are also some questions concerning the type/structure of the artifact(s):

DBAccess uses tycho to build the project. As a result, DBAccess offers a separate p2 "feature" for each supported database platform. Should this translate into separate maven artifacts (with individual GAVs)?
What is the best way to produce these artifacts? Running "mvn install" on the DBAccess project results in nearly 20 artifacts in my local .m2 repository.
For the 1.1 Milestone releases I have been experimenting with staying at the SNAPSHOT version in the poms, so you get the appended timestamps for the resulting plugins and features. This is less effort and avoids sorting issues. It is not a problem as long as people use the p2 update site. For a maven repository, you presumably do not want a SNAPSHOT version?

Best Regards,
Juergen

Hi Björn,
Have you had a chance to look at my proposed solution at [1]?

If you do not have any comments on it, i would just push it from Gerrit to Git. You could then try to consume the maven artifacts from the Hudson build.

Juergen

The DBAccess project now builds Maven artifacts[1].

Until now, the produced repository is only available on Hudson.
You can find it here [2].

Feedback is welcome!

The Maven artifacts of DBAccess have a new group id: org.eclipse.gemini.

As before, the produced repository is only available on Hudson [1].

Feedback is welcome!

Thanks for the good progress Juergen.

Any chance that the artifact is uploaded to a more permanent repository (e.g. Eclipse's Nexus repo or Gemini's shared maven repo) ?

Thanks,
Romain.

Hi Romain,

it would be great if you could give me some feedback on the maven repository.

With Milestone 4, which has been released recently, there is proper (milestone) repository. You can find the information here [1].

Please let me know if you run into problems.

Best Regards,
Juergen

Thanks for the quick answer! I will try to integrate Milestone 4 in my build and will post the result here.

I see that the milestones are published to [1]. Is the plan to merge this repo to the shared Gemini maven repo [2] when the final version is released ? If yes, why use a separate repo ?
Are there plans to use Eclipse's Nexus repo [3] at some point ?

Sorry for the many questions, I'd just want to make sure I understand Gemeini's approach, that will help making our builds resilient to changes.

Romain.

You are right: As soon as Gemini DBAccess 1.1 is released, it will be available in the Gemini repository [2].

The Nexus repository at Eclipse [2] is still work in progress. On its wiki page [3] it is described as "prototype undergoing creation". Gemini does not (yet) have plans to offer its artifacts there. But it is certainly worth at thought.

I confirm that DBAccess's milestone Maven repository works fine for me for the 1.1.0.RC1 artifacts.

I believe it would be easier to publish those artifacts to Gemini's shared repository though, so that users don't have to manage multiple Maven repositories.

Thanks for the hard work!
Romain.

Hi Romain,

thanks for the valuable feedback!

I hope to be able to release DBAccess middle of February. I have already started the release review process. As soon as DBAccess is released, it will go into the common Gemini Maven repository[1].

At the last Gemini sync meeting [4], I have raised the question about the Nexus repository you mentioned previously [2,3]. We will try to find out more about it to see if fits our needs.

Best Regards,
Juergen

I have posted the question about the Maven/Nexus repository [1] to the dash-dev mailing list.

Here is Jesse McConnell's comprehensive answer [2].

Thanks for the follow-up Juergen, I appreciate the effort in sorting this through.

The reasons mentioned in the blog post "Why Putting Repositories in your POMs is a Bad Idea" [1] referenced by Jesse McConnell are precisely why I asked about the possibility of a shared repository in the first place. I'd like to rely on as few 3d party repos (i.e. non-Central) as possible.

FYI, from my own perspective as a user:

- Ideally, the released bundles would be available from Maven Central. Sonatype's OSS repository hosting really helps.
- If not possible, I'm OK with referencing a single stable Gemini repo - I understand Eclipse's Nexus instance is a work in progress
- I'm not fond of having separate repos for milestones (and I don't really undertand the rationale, maybe it's linked with Gemini's own release/build process) -- but I will certainly not use milestones in production anyway.

Thanks!
Romain.
