The main issue is that for dep resolution it still needs something

Why is it bad to use the maven repos instead of copying things from
java/lib?
It makes reproducible builds hard/impossible and doesn't play well
with package systems.
I have not seen the former issue.. but I will trust you on it. On
the latter (package systems) using maven repos seems no worse then
what is being done now.
The issue with using maven repos is that if you happen to use svn to
rollback to a version where we were using maven, the build will most
likely fail because it is dependent on a set of external maven repos
that are no longer in sync with the needs of that particular revision.
sorry to be dense.. if I am using version 2.2 of a libarary, and then
rollback to version 2.1...how does that cause an issue with the build?
If I try to build an older version of qpid that requires version 2.1,
and the maven repo only has version 2.2 then one of two things will
happen depending on how the pom is configured. If I specify that
revision 2.1 is required in the pom file then the build will break
because version 2.1 of the library is no longer available. If I don't
specify this, then maven will attempt to build against version 2.2 which
may fail due to incompatibilities, and even if it succeeds, it won't be
the same bits I would have gotten had I built against version 2.1.
Ok... I have always used required... so I have never seen it pick the
latest. I have also not seen the items go away.. but I understand the issue.
With ant we have all the dependencies stored in svn, so if I roll back
to an older version of qpid and do a rebuild, then I know I'll get
exactly the same bits I would have gotten had I done a build when that
version was current.
Can the ivy setup Aiden mentioned populate/update the lib directory?
That way they latest can be checked in and we can use a single
depdendency data to build and create poms.
