Subject Re: [PROPOSAL] Remove SNAPSHOT from versioning and keep tags on the release branch
Date Thu, 23 Oct 2014 09:33:16 GMT
I’m -1 on dropping the SNAPSHOT tag.

Snapshots are an integral part of maven building the project. A snapshot is mavens way of
telling that a particular release is still in development and causes different behavior in
how it resolves artifacts. For a developer working only local the problem could be minimal
and in case of problems he could wipe his .m2 directory. However for people using centralized
maven repositories it could cause unintended behavior if snapshot is dropped as maven states
that repositories should never replace an artifact that is pushed as a release artifact (without

The net result of this could be that developers are recompiling a build, but actually running/testing
a completely different version because the repository was not refreshed because a release
version already exists. I would propose to keep the -SNAPSHOT until we have a version that
we actually want to release to the public. Personally i would even be in favor of naming a
RC something like 4.4.99-SNAPSHOT until we push the final build, but that would interfere
with the way we sign and mark releases.

I wouldn’t mind dropping -SNAPSHOT in packaging scripts or anything else that happens with
the source after we finish working on it, but i would like not to have anything without -SNAPSHOT
in our git unless its a final release (or RC in our current way of working).

don’t know if it was GA or some other build. What we can do is, we store the git SHA used
for building/packaging in cloudstack-common package in a text file. So, in future if someone
is not sure they can read the SHA and compare if it was GA or not.

know which deb/rpm version/build they installed and they may not know what git SHA or tag
was used to build them, or if it was GA/official-release or patched.
