Things to do before issuing a new release:
Ensure all new Configuration parameters are documented
Use your IDE to regenerate equals/hashCode for ConfigurationImpl (this is just much safer than trying to inspect the code).
Ensure all public API classes have a proper Javadoc.
Update docs/user-manual/en/versions.md to include appropriate release notes and upgrade instructions. See previous entries for guidance.
Bump the version numbers in example and test poms to the next release version. e.g. 2.0.0
Build the release locally: mvn clean install -Prelease
Test the standalone release (this should be done on windows as well as linux):
If everything is successful follow these next steps to build and publish artifacts to Nexus and send out a release vote.
If you don't have a key to sign the release artifacts you can generate one using this command:
gpg --gen-key
Ensure that your key is listed at https://dist.apache.org/repos/dist/release/activemq/KEYS. If not, generate the key information, e.g.:
gpg --list-sigs username@apache.org > /tmp/key; gpg --armor --export username@apache.org >> /tmp/key
Then send the key information in /tmp/key to private@activemq.apache.org so it can be added.
Add your key id (available via gpg --fingerprint <key>) to the OpenPGP Public Key Primary Fingerprint field at https://id.apache.org/. Note: this is just the key id, not the whole fingerprint.
Before starting make sure you clone a brand new git as follows as the release plugin will use the upstream for pushing the tags:
git clone git://github.com/apache/activemq-artemis.git cd activemq-artemis git remote add upstream https://gitbox.apache.org/repos/asf/activemq-artemis.git
If your git user.email and/or user.name are not set globally then you'll need to set these on the newly clone repository as they will be used during the release process to make commits to the upstream repository, e.g.:
git config user.email "username@apache.org" git config user.name "FirstName LastName"
This should be the same user.email and user.name you use on your main repository.
You will have to use this following maven command to perform the release:
mvn clean release:prepare -DautoVersionSubmodules=true -Prelease
You could optionally set pushChanges=false so the version commit and tag won't be pushed upstream (you would have to do it yourself):
mvn clean release:prepare -DautoVersionSubmodules=true -DpushChanges=false -Prelease
When prompted make sure the next is a major release. Example:
[INFO] Checking dependencies and plugins for snapshots ... What is the release version for "ActiveMQ Artemis Parent"? (org.apache.activemq:artemis-pom) 1.4.0: : What is SCM release tag or label for "ActiveMQ Artemis Parent"? (org.apache.activemq:artemis-pom) artemis-pom-1.4.0: : 1.4.0 What is the new development version for "ActiveMQ Artemis Parent"? (org.apache.activemq:artemis-pom) 1.4.1-SNAPSHOT: : 1.5.0-SNAPSHOT
Otherwise snapshots will be created at 1.4.1 and forgotten. (Unless we ever release 1.4.1 on that example).
For more information look at the prepare plugin:
If you set pushChanges=false then you will have to push the changes manually. The first command is to push the commits which are for changing the <version> in the pom.xml files, and the second push is for the tag, e.g.:
git push upstream git push upstream <version>
Note: The Apache Release plugin does not bump the version on the extraTests module. Release manager should manually bump the version in the test/extra-tests/pom.xml to the next development version.
To upload it to nexus, perform this command:
mvn release:perform -Prelease
Note: this can take quite awhile depending on the speed for your Internet connection.
If something happened during the release upload to nexus, you may need to eventually redo the upload.
There is a release.properties file that is generated at the root of the project during the release. In case you want to upload a previously tagged release, add this file as follows:
scm.url=scm:git:https://github.com/apache/activemq-artemis.git scm.tag=1.4.0
The last step before closing the staging repository is removing the activemq-pom-<version>-source-release.zip. At the moment this artifact is uploaded automatically by the Apache release plugin. In future versions the ActiveMQ Artemis pom will be updated to take this into account.
The file will be located under ./artemis-pom/<version>/
Remove these files manually under Nexus (https://repository.apache.org/#stagingRepositories) while the repository is still open.
Once the file is removed close the staging repo using the “Close” button on Nexus website.
Use the closed staging repo contents to populate the the dist dev svn area with the official release artifacts for voting. Use the script already present in the repo to download the files and populate a new ${CURRENT-RELEASE} dir:
svn co https://dist.apache.org/repos/dist/dev/activemq/activemq-artemis/ cd activemq-artemis ./prepare-release.sh https://repository.apache.org/content/repositories/orgapacheactivemq-${NEXUS-REPO-ID} ${CURRENT-RELEASE}
Give the files a check over and commit the new dir and start a vote if all looks well.
svn add <version> svn commit
Old staged releases can be cleaned out periodically.
Please, include the git-commit-report as part of the release proces. To generate it follow these steps:
$ java -jar git-release-report.jar <checkoutDirectory>/activemq-artemis <checkoutDirectory>/artemis-website commit-report-<version>.html <previous-version> <version> true
real example used on 2.6.1:
$ java -jar git-release-report.jar /work/apache-checkout/activemq-artemis commit-report-2.6.1.html 2.6.0 2.6.1 true
Once all the artifacts are stage then send an email to dev@activemq.apache.org. It should have a subject like [VOTE] Apache ActiveMQ Artemis <version>. Here is an example for the body of the message:
I would like to propose an Apache ActiveMQ Artemis <version> release. We added these new features as part of <version>: [ARTEMIS-123] - Great new feature 1 [ARTEMIS-456] - Great new feature 2 The release notes can be found here: https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=<releaseNotesVersionID>&projectId=12315920 Ths git commit report is here: http://activemq.apache.org/artemis/commit-report-<version>.html Source and binary distributions can be found here: https://dist.apache.org/repos/dist/dev/activemq/activemq-artemis/<version>/ The Maven repository is here: https://repository.apache.org/content/repositories/orgapacheactivemq-<repoID> In case you want to give it a try with the maven repo on examples: http://activemq.apache.org/artemis/docs/latest/hacking-guide/validating-releases.html The source tag: https://gitbox.apache.org/repos/asf/activemq-artemis.git;a=tag;h=refs/tags/<version> I will update the website after the vote has passed. [ ] +1 approve the release as Apache Artemis 2.4.0 [ ] +0 no opinion [ ] -1 disapprove (and reason why) Here's my +1
Rules for the Apache voting process are stipulated here.
Assuming the vote is successful send a email with a subject like [RESULT] [VOTE] Apache ActiveMQ Artemis <version> informing the list about the voting results, e.g.:
Results of the Apache ActiveMQ Artemis <version> release vote. Vote passes with 2 +1 binding votes. The following votes were received: Binding: +1 John Doe +1 Bill Smith Non Binding: +1 Mike Williams Thank you to everyone who contributed and took the time to review the release candidates and vote. I'll move forward with the getting the release out and updating the relevant documentation. Regards
After a successful vote, populate the dist release area using the staged files from the dist dev area to allow them to mirror. Note: this can only be done by a PMC member.
svn cp -m "add files for activemq-artemis-${CURRENT-RELEASE}" https://dist.apache.org/repos/dist/dev/activemq/activemq-artemis/${CURRENT-RELEASE} https://dist.apache.org/repos/dist/release/activemq/activemq-artemis/${CURRENT-RELEASE}
Good mirror coverage can take up to 24 hours. Mirror status can be viewed here.
Go to https://repository.apache.org/#stagingRepositories and click the “Release” button.
Make sure you get a copy of the website at:
svn co https://svn.apache.org/repos/infra/websites/production/activemq/content/artemis/
Once the mirrors are up-to-date then update the following:
gitbook pdf)gitbook epub)gitbook mobi)gitbook pdf)Run svn add for all the added directories & files and then svn commit -m "updates for <version> release".
Note: Generating PDFs, etc. with gitbook requires the installation of Calibre. You can install this manually, but it is recommended you use your platform's package management to install (e.g. sudo apt-get install calibre).
Once the website is updated then send an email with a subject like [ANNOUNCE] ActiveMQ Artemis <version> Released to user@activemq.apache.org & dev@activemq.apache.org, e.g.:
I'm pleased to announce the release of ActiveMQ Artemis <version>. Downloads are now available at: http://activemq.apache.org/artemis/download.html For a complete list of updates: http://activemq.apache.org/artemis/release-notes-<version>.html I would like to highlight these improvements: - Summary of feature 1: <link to relevant documentation> - Summary of feature 2: <link to relevant documentation> - Summary of feature 3: <link to relevant documentation> As usual it contains a handful of bug fixes and other improvements. Many thanks for all the contributors to this release.
Only the current releases should be mirrored. Older releases must be cleared:
svn rm -m "clean out older release" https://dist.apache.org/repos/dist/release/activemq/activemq-artemis/${OLD-RELEASE}
Any links to them on the site must be updated to reference the ASF archive instead at https://archive.apache.org/dist/activemq/activemq-artemis/ (this should already have been done implicitly in the previous step).
Ensure old releases are only removed after the site is updated in order to avoid broken links.
