1. I don't think maven scans all the repositories to select the latest
SNAPSHOT. It probably uses the one it finds first.
2. No, we can't use SNAPSHOT dependency on external artifacts with the
current build infrastructure. I understand why developers want to have
such SNAPSHOT dependencies and that is exactly why I asked build team to
change build scripts to accommodate them, but they were never implemented.
3. The reason for not using SNAPSHOT in the current workspace is to make
builds reproducible.
e.g.,
day #1:
---------
User A publishes foo-1.0-SNAPSHOT.jar containing Bar.class
User A changes v3 to use Bar.class and checks in rev #1.
User B checks out v3 rev #1. It builds fine.
day #2
--------
User A republish foo-1.0-SNAPSHOT.jar which does not contain Bar.class
anymore.
User A makes necessary changes in v3 and checks in rev #2.
User B wants to do a clean build of his v3 workspace (remember he is
still on rev #1, because he does not have time to update to latest
workspace, as he is in the middle of his changes). If he cleans his
maven repo, he can't build v3 anymore, as it won't find B.class.
Similarly, anyone who wants to build v3 rev#1 from a clean state, they
can't build. I think this is a big problem.
4. It is really bad idea to make builds available that can't be
reproduced. I see this is being done currently for 3.0-Preview nightly
and trunk nightly builds.
5. If we really want SNAPSHOT integration of external dependencies, we
should investigate the proposal I had put forward sometime back.
6. Cross posting of artifacts is not such a good idea. We will continue
to have such issues unless we restrict access to maven repos.
