This page is a guide, to making a release for the BookKeeper project. It's based off the Whirr instructions and our experience releasing.
There are a few things which you need to set up before making a release.
You should have a 4096 bit RSA PGP key for signing the release. This key should be in the Apache web of trust. Once generated, ensure your key is in https://svn.apache.org/repos/asf/bookkeeper/dist/KEYS.
Put the following in ~/.m2/settings.xml. This will allow you to release and deploy to the apache maven repositories. Of course, it's best not to store your password in cleartext. See http://maven.apache.org/guides/mini/guide-encryption.html for a guide on how to make this a little more secure.
<settings> <servers> <server> <id>apache.snapshots.https</id> <username>APACHE-ID</username> <password>APACHE-PASSWORD</password> </server> <server> <id>apache.staging.https</id> <username>APACHE-ID</username> <password>APACHE-PASSWORD</password> </server> <server> <id>apache.releases.https</id> <username>APACHE-ID</username> <password>APACHE-PASSWORD</password> </server> </servers> </settings> |
The release procedure will require multiple logins to people.apache.org. To avoid having to log in many times, ensure that you have ssh password less login set up for people.apache.org.
The steps for releasing are as follows.
This only needs to be done for the first release of a series, (e.g. It needs to be done for 4.1.0 but not for 4.1.1 or 4.1.2).
Create a branch for the release:
svn copy https://svn.apache.org/repos/asf/zookeeper/bookkeeper/trunk \ https://svn.apache.org/repos/asf/zookeeper/bookkeeper/branches/branch-X.Y -m "Branching for X.Y releases" |
Check out the new branch.
On trunk
Generate the release notes from JIRA. https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12311293
Select the correct version, in HTML format. Make it look like previous release notes. https://svn.apache.org/repos/asf/bookkeeper/site/content/docs/r4.1.0/releaseNotes.textile
Generate a list of all issues committed since last release. In this example, the last release was release-4.2.3, so we want to see all changes since that tag.
bookkeeper$ git log release-4.2.3..HEAD |
Manually check that the list from JIRA, GIT and CHANGES.txt all reflect the same changes.
Update CHANGES.txt using the JIRA release notes in text format.
Make sure the branch builds cleanly. Check for errors and warnings in the output.
mvn clean findbugs:findbugs apache-rat:check install |
Then build the artifacts.
mvn clean package assembly:single -DskipTests |
This will generate
Extract each of the generated artifacts;
Create a directory and copy the three tar.gz packages into it. Sign and generate md5 & sha1 hashes for each package.
md5sum <FILE>.tar.gz > <FILE>.tar.gz.md5 shasum <FILE>.tar.gz > <FILE>.tar.gz.sha1 gpg --armor -u yourname@apache.org --output <FILE>.tar.gz.asc --detach-sig <FILE>.tar.gz |
Add these files to a directory in https://dist.apache.org/repos/dist/dev/bookkeeper (this is a subversion repo), naming it bookkeeper-<VERSION>-candidate-0.
mvn clean deploy -Pdeploy |
This will ask for your gpg passphrase.
Login to https://repository.apache.org using your Apache SVN credentials. Click on Staging on the left. Then click on org.apache.bookkeeper in the list of repositories. In the panel below you should see an open repository that is linked to your username and IP. Select this repository and click Close. This will close the repository from future deployments and make it available for others to view.
Commit changes to git, tag, and push:
git tag -u <your-gpg-key> release-4.2.4 -m "BookKeeper Release 4.2.4" git push origin release-4.2.4 |
Send a mail like the following, updating the relevant content.

Note that we are voting upon the source (tag), binaries are provided for convenience. Source and binary files: https://dist.apache.org/repos/dist/dev/bookkeeper/bookkeeper-X.Y.Z-candidate-0/ Maven staging repo: https://repository.apache.org/content/repositories/orgapachebookkeeper-169/ The tag to be voted upon: release-X.Y.Z (21f4a4cffefaa9391b79d79a7849da9c539af834) BookKeeper's KEYS file containing PGP keys we use to sign the release: https://dist.apache.org/repos/dist/release/bookkeeper/KEYS Please download the the source package, and follow the README to build and run a bookkeeper and hedwig service. |
Move the release candidate into the release directory in subversion, stripping the candidate part from its name.
svn move https://dist.apache.org/repos/dist/dev/bookkeeper/bookkeeper-X.Y.Z-candidate-0 https://dist.apache.org/repos/dist/release/bookkeeper/bookkeeper-X.Y.Z |
Remove the old releases from the release directory in subversion (we only need the latest release there, older releases are available through the archive):
svn rm https://dist.apache.org/repos/dist/dev/bookkeeper/bookkeeper-X.Y.Z |
Release the repository in maven. Log in to https://repository.apache.org, click on Staging on the left. Select the repository that you closed earlier, and click Release, using a description like "Apache BookKeeper X.Y.Z artifacts". This will make the artifacts publicly available.
See Building the website and documentation. Follow the pattern used for previous releases. Add the documentation for the release, the release notes, and link in the releases page and an update in the new page.
Assuming 24 hours have passed since releasing the artifacts, send a mail like the following.
