Version 5.4.9 missing on Maven Central

[mkczyk]

Hi,

On Maven Central there are versions 5.4.8 and 5.4.10, but 5.4.9 is missing:
https://central.sonatype.com/artifact/org.jgroups/jgroups/versions

However, on GitHub I can see the 5.4.9 tag:
https://github.com/belaban/JGroups/releases/tag/jgroups-5.4.9.Final

Is this a bug during upload to Maven Central, and will this version appear again, or was it removed intentionally for some reason?

@mkczyk Maven Central has stricter rules for publishing Maven artifacts than the JBoss Nexus has, see https://central.sonatype.org/publish/requirements/

This release is very likely not syncable to central due to some violation of the above and is only available in JBoss Nexus repository.

We have fixed it since and everything is being synced to central now.

e.g. you can just use

<repositories>
    <repository>
        <id>jboss-nexus</id>
        <name>JBoss Nexus Repository</name>
        <url>https://repository.jboss.org/nexus/content/groups/public/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

Thanks for the clarification.

I noticed that in the listings 5.4.9 and newer are not shown (it ends at 5.4.8):
https://repository.jboss.org/nexus/service/rest/repository/browse/public/org/jgroups/jgroups/
https://repository.jboss.org/nexus/service/rest/repository/browse/releases/org/jgroups/jgroups/
But all versions, including 5.4.9, are present in the metadata:
https://repository.jboss.org/nexus/repository/releases/org/jgroups/jgroups/maven-metadata.xml

That is strange, it's also missing from this browse UI... https://repository.jboss.org/nexus/#browse/browse:releases:org%2Fjgroups%2Fjgroups

@dhladky Can you help us understand why these versions are not browsable anywhere?

[dhladky]

https://repository.jboss.org/nexus/service/rest/repository/browse/public/org/jgroups/jgroups/5.4.9.Final/ is in our Nexus as well. Sometime Nexus does not update browsing index properly. I let it "repair" every weekend so that is probably why it is there already.

Yes, 5.4.9 is missing, but more recent versions are listed on mvn central: [1].

Hello Bela, yes, this is because Sonatype implemented the browsing very poorly and it relies on generated database table, that does not always get the updates it should get. I will run the repair task, however it usually runs about 24 hours and during that time there might be problems with getting other stuff. The files are there and if people use the version in their build, it would work for them, but the directory listing is incomplete.
