Steps for Creating a Release

The Eclipse Hudson infrastructure has Paho builds: https://ci.eclipse.org/paho/

The Hudson job creates jars from the master branch and uploads them to: Paho repository in https://oss.sonatype.org/#nexus-search;quick~org.eclipse.paho

Steps to create a release:

1. Merge all updates from the develop branch into the master branch
2. mvn release:prepare on the master branch will update the pom files to new release version (??) If this step doesn't work, try mvn release:update-versions -DautoVersionSubmodules=true
3. Review and update (if needed) version numbers in the following files: org.eclipse.paho.client.mqttv3.internal.traceformat/build.xml
   org.eclipse.paho.client.mqttv3.repository/category.xml
   org.eclipse.paho.client.mqttv3.repository/pom.xml
   org.eclipse.paho.client.mqttv3.test/pom.xml
   org.eclipse.paho.client.mqttv3/META-INF/MANIFEST.MF
   org.eclipse.paho.client.mqttv3/pom.xml
   org.eclipse.paho.sample.mqttclient/pom.xml
   org.eclipse.paho.sample.mqttclient/src/main/scripts/mqtt-client
   org.eclipse.paho.sample.utility/pom.xml
   pom.xml
   MQTTv3.md
   .github/ISSUE_TEMPLATE
   README.md
4. Check to see if any other files need version number updates
5. on Hudson
   • run paho-java-master-release-01
   • make note of repo ID orgeclipsepaho-????
     
     • example orgeclipsepaho-1023
6. on Hudson
   • Update configuration of paho-java-master-release-02 with repo ID from step 5.
     Example build goal:
     nexus-staging:release -pl org.eclipse.paho.client.mqttv3 -am -DstagingRepositoryId=orgeclipsepaho-1023
   • run paho-java-master-release-02
7. on Hudson
   • run paho-java-master-release-03
8. Tag & sign release on Github:
   • Example: git tag -a -s v1.2.2 -m "Version 1.2.2 - service release"

On successful completion of step 8, new release in Maven central is published by nightly scheduled cron job. So it may take time to get a new release published in Maven central.
