@Yongjun Hong How would be your availability on the weekend and next week? I am going to Spring I/O next week but I should be available on Monday and Wednesday for a sync. If you have not already read the announcement from Sonatype, here is their stance on the end of life for OSSRH in June - https://central.sonatype.org/news/20250326_ossrh_sunset/ There is also an important part here:

Once OSSRH is sunset, we will have more roadmap capacity to begin working on a first-party Gradle plugin. We are working with Sonatype's legal department to streamline the process of open sourcing Central-related plugins. This discussion is currently focused on our Maven plugin, but we intend to launch a first-party Gradle plugin as open source from day one.

TIL: why the precursor of the vanniktech/gradle-maven-publish-plugin was created https://chrisbanes.me/posts/pushing-aars-to-maven-central/

First draft of the cookbook page - https://github.com/gradle/cookbook/pull/47. Just initial guidelines for Gradle users CC @Yongjun Hong

@Yongjun Hong I suggest having a regular sync-up starting from the next week - https://calendly.com/d/cq99-2j6-xws/gsoc-2025-maven-central-publishing-with-gradle We can also do one this week. I am not in the best state after the last week and recovering, but we can find a slot

<!channel> If anyone is interested in joining the sync-ups for the Maven Central Publishing project, please vote here: https://calendly.com/d/cq99-2j6-xws/gsoc-2025-maven-central-publishing-with-gradle .

@Yongjun Hong how is you pre-planning going? Did you have a chance to choose particular issues for NMCP or https://github.com/vanniktech/gradle-maven-publish-plugin?

@Amy Keibler @Joel Orlina @Martin @Gabriel Ittner To summarize today's discussion with @Yongjun Hong, the current plan for the first phase is to build add-on functionality that improves the publishing experience, regardless of the chosen plugin. This would include, as a first deliverable, a DSL for building/extending

pom.xml

definitions based on Gradle metadata/properties and user inputs. The second deliverable is TBD, but we discussed some options including validation of the artifacts or packaging additional data files (e.g. Maven BOMs).

@Sterling ^ this is the chat for Maven Central Publishing BTW

+ @Louis Jacomet too so that we have the key stakeholders from Gradle here, too 🙂

@Yongjun Hong Hi! How is your progress with setting up the repo for your plugin and the first steps?

@Yongjun Hong for your project, maybe you want to take a look at https://github.com/kordamp/pomchecker .

Sonatype Central repository for Maven snapshots is returning 404: https://central.sonatype.com/service/rest/repository/browse/maven-snapshots That endpoint is given in the Sonatype documentation for consuming snapshots.

@Yongjun Hong Good morning. You moved the meeting to tomorrow, right? Just to set an expectation, I have a meeting conflict tomorrow so I'm not 100% sure I will be able to make it. Just to confirm, I am available today for a meeting or for asynchronous discussion.

The Publishing to Maven Central page on the Gradle Cookbook doesn't mention the io.github.gradle-nexus.publish-plugin - is that deliberate?

I'm trying to migrate an existing build from the default maven publish plugin to

com.vanniktech.maven.publish:0.32.0

. I'm getting

Invalid publication 'maven': multiple artifacts with the identical extension and classifier ('jar', 'javadoc').

which is odd because I don't think I've created a

maven

publication. It's a multi-module project, I'm wondering if this is the vanniktech plugin trying to be clever & generating publications I haven't declared?

Added a Slack canvas to this channel. Contributions are welcome!

@Yongjun Hong If you need to estimate my availability when moving a meeting, https://calendly.com/onenashev/virtual-coffee is the best estimation

@Yongjun Hong I'm so sorry, but we have to move the meeting on Wednesday again. I have a court hearing and it looks like it will take longer than initially anticipated. Would you be fine with meeting on Thursday or Friday? My plan for reviews and GitHub issues is today

@Yongjun Hong For testing Gradle plugins: • https://docs.gradle.org/current/userguide/testing_gradle_plugins.html , especially https://docs.gradle.org/current/userguide/testing_gradle_plugins.html#implementing_automated_tests • The patch from the screenshare - https://github.com/YongGoose/kotlin-pom-gradle/pull/12/commits/198641e82e341959aecac3b7703295f67cbf513f

@Yongjun Hong just saw the pings on GitHub. Please do not hesitate to ping here. Sadly, I am on too many projects and my GitHub notifications are overflowing at the moment

Hi, Not sure if this is the correct channel to ask but With the OSSRH being sunset I am no longer able to login to oss.sonatype.com where as I can login to the central.sonatype.org . Is this the expected behaviour ? Also I don't see my namespace(group id) with which I use to publish my android artifacts in the central repository . How can I go about fixing this ?

@Yongjun Hong are we meeting today?

@Yongjun Hong do you want to meet today?

@Martin @Gabriel Ittner @Andres Almiray If you're interested to add short summaries/examples to https://cookbook.gradle.org/integrations/maven-central/publishing/ , I think it would be a win at this stage

FWIW JReleaser provides an example that may be used as a starting point https://jreleaser.org/guide/latest/examples/maven/maven-central.html

has renamed the channel from "maven-central-publishing" to "maven-central"

set the channel description: All things Maven Central related: from publishing to mirroring inside corporate networks

Hey folks, Renamed the channel so that we cover all interactions with Maven Central here: from publishing to mirroring.
