I'd prefer to see some stable artifacts with names like 0.23.0-alpha1,
or 0.20.0-r5545 where the SVN revision is included


Because -SNAPSHOT is pretty much meaningless.

1. At build time it means "the last published version that M2 could be
bothered to download"

2. It's extra meaningless when someone files a bugrep against a SNAPSHOT
version. Which snapshot? Today's? Yesterdays?

3. downstream projects need stable artifacts to build and release
against, so I can say "here is a version that includes the 0.23.0-r5545
alpha release" rather than "here is a version that includes some
snapshot artifact whose provenance is indeterminate.

4. downstream builds will be utterly unreplicable. Just because
everything compiled on the box at time t1=today, if you take my source
tree and try to build at time t2 != t1 it may not compile, let alone work.

I propose that every alpha/beta release has a set of artfacts published
to the stable maven repo with the same version counter as the .tar.gz
artifacts. That way I can set hadoop.version=0.23.0-r5545 and have a
stable build/release process.

IDEs? Not my problem. I can do an ant ivy-retrieve and get the current
artifact set if I want that; for Hadoop I'm more likely to mount the
live svn branch, so that if I get a stack trace I can not only go into
the source, I can change things. For everyone else in my group who
builds, they can get the artifact and src jar from the maven repositories
