Apache Unomi Release Guide
The Apache Unomi project periodically declares and publishes releases. A release is one or more packages of the project artifact(s) that are approved for general public distribution and use. They may come with various degrees of caveat regarding their perceived quality and potential for change, such as "alpha", "beta", "stable", etc.
The Unomi community treats releases with great importance. They are a public face of the project and most users interact with the project only through the releases. Releases are signed off by the entire Unomi community in a public vote.
Each release is executed by a Release Manager, who is selected among the Unomi committers. This document describes the process that the Release Manager follows to perform a release. Any changes to this process should be discussed and adopted on the dev@ mailing list.
The release process consists of several steps:
- Decide to release
- Prepare for the release
- Build a release candidate
- Vote on the release candidate
- During vote process, run validation tests
- If necessary, fix any issues and go back to step 3.
- Finalize the release
- Promote the release
Decide to release
Deciding to release and selecting a Release Manager is the first step of the release process. This is a consensus-based decision of the entire community.
Anybody can propose a release on the dev@ mailing list, giving a solid argument and nominating a committer as the Release Manager (including themselves). There's no formal process, no vote requirements, and no timing requirements. Any objections should be resolved by consensus before starting the release.
In general, the community prefers to have a rotating set of 3-5 Release Managers. Keeping a small core set of managers allows enough people to build expertise in this area and improve processes over time, without Release Managers needing to re-learn the processes for each release. That said, if you are a committer interested in serving the community in this way, please reach out to the community on the dev@ mailing list.
Basically we will be following the procedure described here with a few more steps and details before and after.
Checklist to proceed to the next step
- Community agrees to release
- Community selects a Release Manager
Prepare for the release
- Setup new version in JIRA project
- Update all JIRAs, close the ones that are still not closed, review tickets that can be closed, postpone to another release tickets that are not managed now
- Clone and checkout the project using:
in a separate directory, to make sure you don’t have any additional files in the build (such as allCountries.zip or other binary files that should not be there)
git clone https://gitbox.apache.org/repos/asf/unomi.git
Build the project
- Tests source, javadocs and signature generation using:
mvn clean install -P apache-release,integration-tests
- Make sure we generate all sub-projects using:
mvn clean install -DskipTests=true -P integration-tests,performance-tests,rat,apache-release
- Check that there are no JARs or ZIP files in the source code, you can do this by looking at the generated RAT report here :
- Check that the KEYS file only contains signatures with @apache.org addresses (if there are non @apache.org don’t remove them because they have been used to sign older releases)
- Update the copyright notice years in the NOTICE file and anywhere else where it might be
- If you get JavaDoc errors or other errors you must correct all of them before proceeding further
- If you get a error while signing despite having the proper keys install that looks like this:
you can either try to sign a file like this:
[INFO] --- maven-gpg-plugin:1.5:sign (default) @ unomi-root --- gpg: 'echec de la signature : Inappropriate ioctl for device gpg: signing failed: Inappropriate ioctl for device
this will ask for your password and remember it in the agent for a while, or if you want a more permanent solution: https://dan.cx/2016/11/gpg-inappropriate-ioctl-for-device-errors
gpg -ab test.txt
Publish the release
- Setup server passwords for publishing as document here: https://www.apache.org/dev/publishing-maven-artifacts.html and https://maven.apache.org/guides/mini/guide-encryption.html#How_to_encrypt_server_passwords
- Check into the target directory and unzip the source release and compile it using:
to check that the packaged source build properly
cd target unzip unomi-root-1.4.0-SNAPSHOT-source-release.zip cd unomi-root-1.4.0-SNAPSHOT mvn clean install
- Go back to the root project directory and run:
mvn release:prepare -DskipTests=true -DdryRun=true -P apache-release,integration-tests,performance-tests
- Publish a snapshot to test the deployment passwords:
- Delete the release.properties file
mvn -P apache-release,integration-tests release:prepare
mvn -DskipITs=true -DskipTests=true -P integration-tests release:perform
- If something fails, make sure you first drop the staging repository created here: https://repository.apache.org/#stagingRepositories.
If you need to relaunch the
release:performand don’t have a release.properties, create a
release.propertiesfile with the following contents:
scm.url=scm:git:https://gitbox.apache.org/repos/asf?p=unomi.git scm.tag=unomi-root-1.4.0 and run mvn release:perform
- Make sure you uploaded your public PGP key using:
(get the identifier using gpg --list-secret-keys).
gpg --keyserver hkp://pgp.mit.edu --send-keys KEY_IDENTIFIER
This will be used by the Apache Nexus Repository Manager to validate the JARs uploaded in the staging repository.
- Connect to https://repository.apache
.org/#stagingRepositories and look for the open staging repositories, you should have two (one for everything and the other for KAR/features) for releases <= 1.2 and just one for versions >= 1.3.0 (because of changes in the Karaf plugins). Close the repositories and given a meaningful comment when closing such as:
Apache Unomi 1.4.0 Release
- Send out to the Unomi mailing list a mail to start the voting process, see 
- Send out a vote summary in the same thread to the Unomi mailing list once the voting period has expired, see 
- Upload the source and binary distributions to the Apache Dist repository before the PMC vote:
svn checkout https://dist.apache.org/repos/dist/dev/unomi unomi-dev
cd unomi-dev mkdir 1.4.0
- Copy all the Zip and Tarbars including SHA1/ASC (but do not copy the MD5 sum) files from: https://repository.apache.org/content/repositories/orgapacheunomi-1014/org/apache/unomi/unomi/1.4.0/ and https://repository.apache.org/content/repositories/orgapacheunomi-1014/org/apache/unomi/unomi-root/1.4.0/
Rename the source files to something shorter and consistent with previous releases:
mv unomi-root-1.4.0-source-release.zip unomi-1.4.0-src.zip mv unomi-root-1.4.0-source-release.zip.asc unomi-1.4.0-src.zip.asc mv unomi-root-1.4.0-source-release.zip.md5 unomi-1.4.0-src.zip.md5 mv unomi-root-1.4.0-source-release.zip.sha1 unomi-1.4.0-src.zip.sha1
cd .. svn add 1.4.0
If needed, update the KEYS file (that is in the svn checkout
svn commit -m "Apache 1.4.0 Release (for PMC voting)"
If the vote is refused, you will need to restart the release process. Make sure you remove the staging repositories as well as the release tag. You will also need to reset the version in the project using:
- Promote the staging repositories now that the release is approved
Finalize the release
Move the files uploaded to the unomi-dev repository to the unomi-release repository by doing the following:
svn mv https://dist.apache.org/repos/dist/dev/unomi/1.4.0 https://dist.apache.org/repos/dist/release/unomi/1.4.0 -m "Apache Unomi 1.4.0 Release"
- Update Jenkins
- In JIRA mark the version as released and add a release date
Connect to https://repository.apache.org/#stagingRepositories and look for the open staging repositories, you should have one. Select the staging repositoriy and click on
- Update the website to point to the new release on the download page by first copying the current release to the archive page. Make sure you change the links to use the archive.apache.org instead of the closer.lua script (see other archived versions for example). Then you can update the download page with the proper links to the new release (no direct links to
www.apache.org/dist, make sure you use the closer.lua script). Be careful with links that contain & (ampersand) characters, they must be replaced with & Finally on the home page update the news section to add the release.
- Check the generated site by opening
target/staging/index.htmland check your changes and verify that there are no broken links
- WAIT FOR THE MIRRORS TO SYNC (at least 24 hours)
Upload the site modification by using:
./generate-site-and-upload.sh APACHE_LDAP_USERNAME APACHE_LDAP_PASSWORD
- Delete the tag:
git push --delete origin unomi-root-1.4.0 git tag --delete unomi-root-1.4.0
- Reset to the previous commit before the release preparation:
git reset --hard c65f9897ec5f31d9d22ad639738c7db9d109aa77 git push origin -f
- Send an announce to the project mailing list and the incubator mailing list to announce the new release using mail template 
- If you were releasing from a branch, make sure you merge all the branch changes for the release back to the master.
Tweet, post on Facebook, LinkedIn, and other platforms. Ask other contributors to do the same.
Checklist to declare the process completed
- Release announced on the user@ mailing list.
- Release recorded in reporter.apache.org.
- Release announced on social media.
- Completion declared on the dev@ mailing list.
Improve the process
It is important that we improve the release processes over time. Once you’ve finished the release, please take a step back and look what areas of this process and be improved. Perhaps some part of the process can be simplified. Perhaps parts of this guide can be clarified.
If we have specific ideas, please start a discussion on the dev@ mailing list and/or propose a pull request to update this guide. Thanks!
