erronous requirements in p2 cause eclipse product export to fail

Using buckminster: complains on com.eclipsesource.jaxrs.consumer.source

It's the same you saw in the target editor. I don't know buckminster well but is there a way to disable p2.greedy?

[dcaillia]

So far the only answer i got (from buckminster-dev mailing list) to this question was: "no, I don't think there is a way to disable it in p2 ... its a function of how the IU/bundle was defined and published". Any chance you'ld consider to change the dependencies such that the problem goes away?

Please be aware that this problem is not only for buckminster, but also for the regular eclipse pde product export wizard.

[hstaudacher]

Alright, so we are using the p2 repository for several projects without any problems. I can't spend the effort to investigate here. But I would be happy if you can resolve the problem in a fork and open a pull request. I will then verify it.

We also use the p2 repo with tycho without any problems.

I've removed the dependencies to the *.sources bundles from build/com.eclipsesource.jaxrs.connector.feature/feature.xml and build/com.eclipsesource.jaxrs.jersey.runtime.feature/feature.xml, this fixes the problem.

Therefore i think the complete solution is to have a separate feature for source bundles. Is there any particular reason why you chose to put them together with the binary bundles?

[hstaudacher]

No special reason. As more as I think about it I thin it's a stupid idea to put them in one feature.

Would you like to create a source feature or should I?

[dcaillia]

It's my first time on github and tycho, so it's a good exercise for me, but i don't know if i'll manage it soon. I'll try to make a pull request :) later today.
