This is a how to document for creating Apache Jackrabbit releases. It documents the current release process and needs to be updated as we move forward.
Jackrabbit releases are created based on user demand and the availability of fixes and other requested changes. Any committer can declare their plan to cut a release by sending a "Apache Jackrabbit x.y.z release plan" message to the dev@ list. The plan should refer to Jira for the list of fixes to be included in the release and give a rough estimate of the release schedule. It's OK to revise the plan if needed.
If you're not a committer, you can send a message to the mailing list asking for a new release to be made. Including the list of specific fixes you need and a short rationale of why you need the release.
You need to be a Jackrabbit committer to prepare and perform a release, but anyone is welcome to help test the release candidates and comment on the release plans.
You should have a code signing key that is included in the Jackrabbit KEYS file. See Appendix A at the end of this page for more details.
- Make sure that an appropriate version for the release is entered in Jira and that all the related issues have been resolved.
- Create a RELEASE-NOTES.txt file in the root folder of the project to be released. If such a file already exists, update it for the release. When done, commit the file. See previous release notes for examples of what to include. The release note report in Jira is a useful source of required information.
- Build and deploy the release artifacts with Maven. See below for the exact steps.
- Close the staged repository on repository.apache.org.
- Upload the artifacts to https://dist.apache.org/repos/dist/dev/jackrabbit/ (instructions at the end of the build)
- Start the vote thread, wait 72 hours. See the vote template generated by the Maven build.
- If the vote fails (easy case first) remove the tag from svn and drop the staged repository - done
- If the vote is successful
- close the vote by publishing the results
- copy the release candidate from dev/jackrabbit to release/jackrabbit in https://dist.apche.org/repos/dist/, and delete any older releases from the same branch (they're automatically archived),
- release the staged repository for synchronization to Maven central.
- mark the version as released in Jira: Jira Project Home -> Project Summary -> Administer Project. Under Versions, click <More>. You'll see all the defined project versions. From the settings menu, choose 'Release' on the version.
- close all the issues included in the release: Jira Project Home -> Change Log -> Choose the released version. From the issue list you have the option to bulk update all of the included issues. Just 'Transition Issues' from 'Resolved' to 'Closed' and you are done!
- Update the Jackrabbit web site to point to the new release.
- Send the release announcement once the web site and download mirrors have been synced.
The release is built using the Maven release plugin. See the Releasing a Maven project guide for more details. Make sure you have added the pgp key information in you maven settings file, especially if you have more than one key installed locally. See Appendix B for the details.
- Execute mvn release:prepare. This will update the POM files and tag the release in svn.
- Execute mvn release:perform. This will build the tagged release and deploy the artifacts to a staging repository on repository.apache.org. The non-Maven release artifacts are automatically deployed to your home directory on people.apache.org. You only need to add the keyname if you have multiple keys and the code signing keys is not your default key.
Follow these instructions to generate your code signing key and to add it to the Jackrabbit KEYS file.
- Generate a code signing key using your @apache.org address as the email and "CODE SIGNING KEY" as the comment.
- The Jackrabbit KEYS file is managed in https://svn.apache.org/repos/asf/jackrabbit/dist/KEYS. To modify the file, first checkout the dist directory:
- See the beginning of the KEYS file for instructions on how to append your key to the file.
- Once you've committed the changes, update the KEYS file on people.apache.org:
- You are DONE, but to see the changes on http://www.apache.org/dist/jackrabbit/KEYS you must wait 2 hours
You should get your key linked to the Apache web of trust. Once other people have signed your key, you can update the KEYS file with the signatures you've received.
