like the approach of everybody contributing their latest
release to a new kind of repo.
I’m wondering what happens when the dependencies are not
aligned. For example GEF ships a new version but GMF ranges
don’t allow for it. Does the repo contain two versions of
GEF or is GMF not included?
if we step back, the issue I’m describing is caused by the
fact that the release repo is validated (validated means all
the IUs in the repo can be installed together, to the
exception of a couple IUs) in order to reduce the number of
install time dependency resolution errors. However I’m
thinking that now that p2 has the remediation mechanism ,
the necessity to have a validated repo is lessened since at
install time p2 will figure out the right set of things to
install (as well as things to uninstall and update), and in
the case of a check for updates it will only propose the
versions that can work together.
advantage of shipping a non validated repo is that it
reduces the burden of integration since the process of
creating the repo is just a mirroring one.
that said, I think that in addition to this new repo, there
would still be value in creating a release repo where the
content is validated and more stable.
another thing to consider is which repo would users build
projects contribute the latest finished release they
have, dependencies are reconciled, some cross-testing
happens and it’s out. Every month, there is a repo with
versions of all participating projects that are known to
work together. Users are happy because they only need to
check for updates from the aggregate repository that
delivers new stuff to them frequently. Projects are
happy because they can set schedules that make sense for
their needs and if they miss one deadline, the next
opportunity is not that far away.
I think this is exactly what projects and
Being up-to-date makes aggregation
repositories (look at maven central) valuable.
