Hi
I had the same problem in with the NAR plugin at the time. No way to
make those SNAPSHOTS
work if you deploy multi-platform artifacts with classifiers. I hope
this can be fixed in 3.0 as
there did not seem a way out in 2.x for NAR to handle it correctly.

Why not just incorporate the full coordinate in the metadata. This
is also a problem for finding attached artifacts like javadocs and
sources. There is no record of them in the metadata. If we had a
complete catalog of the the artifacts deployed and not just for the
primary this would not be an issues, yes?

I was recently working with a customer to move them off of using
non-unique snapshots for various reasons. In the process we
discovered
a problem with snapshots, classifiers and multi-platform builds.
In this scenario, we have a project that is built on multiple
platforms, say windows, solaris and mac. The binaries must be built
on
the target platform. The source is the same, so the gav is the
same. A
CI build actually consists of 3 builds running in parallel. Each
build
deploys a classified artifact where the classifier is the platform,
ie
[windows|solaris|mac].
When we flipped them over to using timestamped snapshots, we
uncovered
a problem. As each build finishes, maven increments the timestamp and
build number and deploys their artifacts. The trouble is that each
timestamped build consists of only 1/3 of the classified artifacts.
So
for example, once the Mac target is deployed, the Windows SNAPSHOT
version is no longer able to be located because the maven-
metadata.xml
says the latest is the Mac only build.
Since the source in this case is identical, having separate modules
for this seems out of the way. Classifier really is the right way to
distinguish between different flavors normally, but obviously this
doesn't work well when you have to produce the artifacts from
separate
mvn invocations.
It feels to me like we need some better support in Maven to handle
these types of multi-platform builds, but I'm curious how people are
handling it now?
