Re: [tycho-user] dependencies not found in p2 repo build

[Tim Harsch <tharsch@xxxxxxxxxxxx>]

Right, that's what I think I'm coming to understand.  So...

Case 1) It seems to me, it wouldn't have to be that way, if I could tell
tycho that for this particular bundle, not to worry that it can't be
resolved.  In other words, I know my plugin that requires sesame loads
into the OSGI container and runs fine without opencsv, so why should tycho
break the build?  Shouldn't tycho give special consideration to the fact
that it is scope=runtime and not attempt to pull it in to the build?

Case 2) If I do make the plain jar for opencsv a bundle, using
maven-bundle-plugin, how would tycho know to use that one and not the one
in my .m2 repo?  Since it is a transitive dependency tycho will download
the jar at resolution time.  Unless, maybe, I delete it from repo, and
install a custom one to the repo via install:install-file, but that seems
like witchery to me.  Is there a way to tell tycho to use a directory
location with precedence of the .m2 repo?

Additionally, do the repositories of layout=p2 take any precedence over
the local .m2? artifacts resolved from the p2 repos aren't cached in the
.m2 local repo as far as I can tellŠ so which gets searched first when
<pomDependencies>consider</pomDependencies> is in effect?

Thanks,
Tim
