Sorry, if I was unclear.

if you set the repository as false it won't be considered by maven in order to looking for remote artfacts/bundles. but maven can
still use already downloaded ones.
Here I wasn't asking about disabling a repo, but about restricting downloads
from it so that you only get release artifacts, not snapshots.
More precisely, what rules Maven applies when it finds the above element
in a repository declaration, or: how exactly does Maven recognize an
artifact as a snapshot.
Consider a company repository manager standing between you and
the outside, i.e., you can't directly turn on/off your connection
to OSSRH snapshots, but need to excluded snapshots in a given build.
if you have Nexus OSS free(https://www.sonatype.com/download-oss-sonatype), you can start and stop a snapshot that is exposed to the
world or internal network.
I don't operate the nexus. In that role I just need to ensure that the
intended versions are fetched from it. Consider this scenario as an
illustration for the above question.
and if we use thirty-part snapshot repo or p2 bundles, what I normally used to do at dev time (briefly) are:
* Download the bundles from the http links provided by Eclipse and create a local maven repository and point nexus to it (the most
* create a new branch in our releng project in git where I will change the FPOM ( a fragment POM with only dependencyManagement
and version that I want to work). Normally I declare every dependency, including transitive ones. Then I install those fpom in
maven snapshot repo;
* create a branch for consumer projects and change every multi-project root pom that imports fpom to use the snapshot and
consequently all hierarchy below it will have the right versions ( I use versions plugin for that):
Up-to this point this roughly corresponds to what I wrote about a huge dependencyManagement
as a stand-in for a target platform definition. We seem to be on the same page, good.
Thinking more about it, we might consider publishing this kind of target platform definition
in the future, s.t. like
containing dependencyManagement with all exact versions as of Oxygen GA.
I filed https://bugs.eclipse.org/515137
In that repo I see artifacts like this:
which exhibits two variants of the version: directory mentions SNAPSHOT,
artifact expands that to a time stamp. Is this artifact enabled/disabled
by the <snapshots> element? If so, then this could help avoid the problem
I mentioned in my first mail.
The first variation that you see is the directory. inside that directory you can have one or more different timestamped versions.
what defines which one is the latest is the
I know what is a directory ;p
But I still don't know how exactly versions in directory names and/or artifact names
must be constructed to be (negatively) affected by
I'm insisting in this point, because only if this is fully understood,
someone may publish snapshots to a global repository without affecting
consumers who rely on receiving release artifacts only.
