Re: [equinox-dev] Maven snapshot repository available ?

[Stephan Herrmann <stephan.herrmann@xxxxxxxxx>]

Let me directly add some words of caution:

When pushing Eclipse artifacts to Maven Central we convert
OSGi 4 part versions to 3 part versions as suitable for a Maven Release.

When anybody starts to publish snapshots they should be very
careful in testing that snapshots don't interfere with builds
requesting a release version. Example: [4.6.0,4.7.0) should
select any of 4.6.1, 4.6.2 ... but *not* 4.7.0.
As soon as a snapshot exists, e.g., as 4.7.0.v2017040112000
then this version would be considered (by some maven versions)
as < 4.7.0 and thus be picked via the above version range.
Client builds using Maven may not customarily use such version
ranges, but dependencies among Eclipse artifacts do make use
of semantic versioning and thus could be wired in incompatible
ways.

One way around this, *might* be to publish / consume snapshots
only via repo.eclipse.org, not Maven Central. This would leave
the due diligence to consumers, who only have to ensure that
artifacts from repo.eclipse.org don't accidentally creep into
release builds via their local maven repository.

Another way, might be to enhance the aggregator to create literally
4.7.0-SNAPSHOT versions (no qualifier expansion). So far, however,
I don't see huge demand for this.

Yep, there's plenty of ways how Maven can get confused (to say
the least) about mavenized OSGi artifacts.

cheers,
Stephan
