     - Publishing to maven should happen by at least Tuesday before the release since there is up to a 24 hour delay for the maven mirrors.
-    - Update [SDK4Mvn.aggr](https://github.com/eclipse-platform/eclipse.platform.releng/blob/master/publish-to-maven-central/SDK4Mvn.aggr) to the release build.

+    - Run the [Publish to Maven](https://ci.eclipse.org/releng/job/Releng/job/PublishToMaven/) job in jenkins with the `release` parameter and the release build as `sourceRepository`.
     - Once that publish job has completed successfully, log into https://oss.sonatype.org/#stagingRepositories and close the Platform, JDT and PDE repositories.
       - If you do not have an account on oss.sonatype.org for performing the rest of the release request one by creating an issue like https://issues.sonatype.org/browse/OSSRH-43870 to get permissions for platform, JDT and PDE projects and tag an existing release engineer to give approval.
