OSSRH: Migrate Namespace to Maven Central

[Weltraumschaf]

Today got this reminder per Mail:

NOTE: If you have already migrated your namespace(s) to Maven Central this email does not apply to you and thank you for your initiative.

Greetings OSSRH Publisher,

As you may have heard, OSSRH is reaching end of life on June 30, 2025. OSSRH users need to migrate their namespaces to the Central Portal as soon as possible.

Instructions for self migration are located here: https://central.sonatype.org/faq/what-is-different-between-central-portal-and-legacy-ossrh/#self-service-migration

To make the transition smoother we will be automatically migrating publishers that have not used oss.sonatype.org or s01.sonatype.org to publish artifacts in some time starting with the oldest and working our way forward. To avoid disruption to your publishing processes we strongly encourage migrating before the June 30, 2025 deadline.

Thank you for your assistance,

The Central Team

Docs: What is different between Central Portal and Legacy OSSRH?

[Weltraumschaf]

From docs:

How do I know if I am on Legacy OSSRH?

If you use https://oss.sonatype.org or https://s01.sonatype.org to publish, you are publishing via the Legacy OSSRH service. If you are publishing via a build tool integration, this might be configured as a default, so check the plugin's documentation to be sure, if you didn't manually specify a URL.

We're affected:

docs/release.md
31:- Upload the resulting artifacts to [Sonatype Nexus](https://oss.sonatype.org/) and stage them.

pom.xml
198:      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
202:      <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
350:            <nexusUrl>https://oss.sonatype.org/</nexusUrl>
