View source for Platform-releng/Publish to Maven Central

== Purpose == 
We publish Eclipse platform(includes equinox), PDE and JDT(including ECJ) to maven central. This document describes the process used.

=== Getting user accounts ===
1. Create user account using https://issues.sonatype.org/secure/Signup!default.jspa

2. Create a issue on Jira to get permissions for platform, JDT and PDE projects. Ref: https://issues.sonatype.org/browse/OSSRH-43870 for template

=== Process ===
When user runs stage 1 copy and rename job(https://ci.eclipse.org/releng/job/eclipse.releng.renameAndPromote/) the final release URLs for the eclipse release gets created. We use these URLs in this process. 

1. Update https://github.com/eclipse-platform/eclipse.platform.releng/blob/master/publish-to-maven-central/SDK4Mvn.aggr with the new URLs. Please make sure to update not only eclipse urls but emf and orbit as well

2. Update https://github.com/eclipse-platform/eclipse.platform.releng/blob/master/publish-to-maven-central/properties.sh with new build versions and repo locations

3. Run https://ci.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/CBIaggregator/ job. This will create an intermediate repo conforming to maven central. This also created baseline-next.txt for later use. This can be found in the workspace root.

4. Run https://ci.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/PublishJDTtoMaven/, https://ci.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/PublishPDEToMaven/ and https://ci.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/PublishPlatformToMaven/ to publish to maven central's staging repo. The parameter required is the build number from  https://ci.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/CBIaggregator/ please provide last successful build's number.

5. Close the maven staging repos by logging in to https://oss.sonatype.org/#stagingRepositories,  selecting Repositories orgeclipsejdt-*, orgeclipsepde-*, orgeclipseplatform-* and clicking on close button.

6. Release these repos by selecting them and click on release.

7. Replace contents of https://github.com/eclipse-platform/eclipse.platform.releng/blob/master/publish-to-maven-central/baseline.txt with the contents of baseline-next.txt created in step 3.
