Hi Nicholas,
the Snapshots are generated nightly by Jenkins: * Main: https://ci-builds.apache.org/job/Lucene/job/Lucene-Maven-Snapshots-main/ * 8.x: https://ci-builds.apache.org/job/Lucene/job/Lucene-Solr-Maven-8.x/ About your questions: The snapshots pile up, so there is relics of outdated modules that were deleted. E.g., lucene-spatial no longer exists and was replaced by lucene-spatial3d. Because of this you see some old artifacts that were published when it was still active. As no new artifacts are pushed, the last 10 old ones per version number stay there forever. During 8.x there is a gap because the snapshot build was broken for about 1.5 years. So the last ones were 8.3.2. It was reactivated for 8.9.0 (see https://issues.apache.org/jira/browse/LUCENE-9836). Snapshot version numbers are always slightly different. You wont use direct version numbers. If you want to refer to a snapshot artifact you would use the -SNAPSHOT version number, whoich downloads the latest one. For Solr it’s a bit different now, we do not rely on snapshots anymore (too uncontrollable). There we build “real” (non-snapshot) prereleases which are located on some separate repository with version numbers after the Jenkins build number. The builds are manually triggered when Solr decides to upgrade Lucene, it is not automatic: https://ci-builds.apache.org/job/Solr/job/Lucene-prerelease-main/ Artifacts are here (one repository per “release”): https://nightlies.apache.org/solr/lucene-prereleases/ (latest is jenkins build 5) Uwe ----- Uwe Schindler Achterdiek 19, D-28357 Bremen https://www.thetaphi.de eMail: u...@thetaphi.de From: Nicholas Knize <nkn...@gmail.com> Sent: Friday, June 4, 2021 1:00 AM To: Lucene/Solr dev <dev@lucene.apache.org> Subject: Re: SNAPSHOT builds Also, lucene-spatial module's last release was 8.4. So I'm confused why there are any artifacts past 8.4 let alone one built in 2019 for 9.0.0? Seems like all the modules should be consistent on a consistent SHA? Is this snapshot repository used for anything?

Are they auto published somehow or manually published? Looks like the artifacts include timestamp and build identifier but all the modules seem to be built at different times and are not consistent with each other (e.g., lucene-core-9.0.0 <https://repository.apache.org/content/groups/snapshots/org/apache/lucene/lucene-core/9.0.0-SNAPSHOT/> snapshot was recently published, but lucene-spatial-9.0.0 <https://repository.apache.org/content/groups/snapshots/org/apache/lucene/lucene-spatial/9.0.0-SNAPSHOT/> snapshot was last built Dec 12, 2019).
