This document summarizes the steps of release procedure for Qpid Java Components
Pre-Requirements
The release procedure is based on Apache Release Policy, Release Signing and Publishing of Maven Documents
PGP
Release artifacts needs to be signed. GNU Privacy Guard from OpenPGP is used to sign on Apache. Please, refer Release Signing about PGP public key cryptography. The document contains basic information about release signing and contains link to various resources about PGP public key cryptography and how to use GNU Privacy Guard to generate and sign the PGP keys. Install GNU Privacy Guard, generate keys following steps provided here and publish public keys
Maven
Maven is used to build and manage Qpid Java project. 3.x version of maven needs to be installed and setup the development environment as describedat Publishing of Maven Documents.
Please, note that repository id (server id) in setting xml should be apache.releases.https. Using different id would result in failures to publish release artifacts into staging maven repo.
Java
JDK 1.7 is required to compile java classes. Thus, install latest 1.7 JDK. 1.7.0_80 JDK was the latest at the moment of writing this document.
SVN
Sources are kept in SVN repo. Thus svn client is required
Major version release
Checkout Qpid sources from trunk using svn client. Alternatively, git and git-svn can be used.
svn co https://svn.apache.org/repos/asf/qpid/java/trunk qpid-java cd ./qpid-java
Check that you can build using profile apache-release
mvn clean install -Papache-release -DskipTests
The build should finish successfully. The gpg plugin will prompt for the password of PGP signing key.
Run RAT tool to verify that all source files have license headers
mvn apache-rat:check
Add license headers to the files which do not have one or update RAT excludes if required.
Verify third party licenses
mvn -Pdependency-check prepare-package
Build alpha
Alpha does not requires branching. Thus, it can be built using maven versions plugin to change version and revert it back after build and deploy, for examplemvn versions:set -DnewVersion=6.0.0-alpha ; mvn clean install deploy -Papache-release ; mvn versions:revert
- The build is deployed into staging repository, which needs to be closed in order to be available. Log in into Apache Nexus UI, select the repository under "Staging Repository" and click Close button to close staging repository for any publishing of artifacts. After closing, a permanent link to the staging repository will be available.
- Send an email into users@qpid.apache.org about alpha availability with a link to the staging repository
- When beta is ready to be created and published, delete the staging repository by logging into Apache Nexus UI, selecting the repository and clicking "Drop" button.
- Check JIRA system for any unresolved JIRAs for the release and notify authors about the release
Cut the branch using release:branch. Please, refer maven release plugin documentation for more details
mvn release:branch -DbranchName=6.0.x -DupdateBranchVersions=false -DupdateWorkingCopyVersions=true -DautoVersionSubmodules=true
Checkout branch sources, for example
svn co https://svn.apache.org/repos/asf/qpid/java/branches/6.0.x cd 6.0.x
Cut the tag and build the release build using maven:prepare
mvn release:clean mvn release:prepare -Papache-release,java-mms.0-9 -DautoVersionSubmodules=true -DpreparationGoals=test
Preparing the release will create the new tag in SVN, automatically checking in on your behalf.
Stage the release for voting
mvn release:perform -Papache-release,java-mms.0-9 -Darguments="-DskipTests"
- The build is deployed into staging repository, which needs to be closed in order to be accessible. Log into Apache Nexus UI, select the repository under "Staging Repository" and click Close button to close staging repository for any publishing of artifacts. After closing, a permanent link to the staging repository will be available.
- Send an email into users@qpid.apache.org about RC availability with a link to the staging repository
- If RC is OK and voting passes, promote the artifacts from staging repository into the world by pressing Release button in Apache Nexus UI.
Otherwise, drop staging repository and repeat steps 12-16 until voting passes. - Update Qpid web site Qpid Java Component pages and publish new release documentation.
The website readme has more detail about these steps.
- Generate new release content
- Add any additional notes desired to the generated release notes
- Change current release version
- Update release references in other parts of the site - Mark release as released in JIRA and close any unresolved JIRAs if required
- Wait for 24 hours after closing the voting and send the release notification email into users@qpid.apache.org
Minor release procedure
Follow the steps 11-19 from Major release procedure. If required, it can include steps 3-9 for running RAT, verifying licenses and building alpha (with difference of checking out sources from svn branch).
