Making an OpenJPA 1.0.x or 1.1.x Release
These instructions guide the release manager through the steps of making an official OpenJPA release.
Prerequisites
- You should read the OpenJPA Release Policy to decide on the name of the new release, based on the content.
- You should read the Apache Release FAQ
- You must have shell access to people.apache.org
- You must have the following utilities installed on your local machine and available in your path:
- For Windows users, install Cygwin in addition to the above utilities
- Make sure the Net/openssh and Utils/gnupg packages are installed that come with Cygwin installation.
- Optional: Putty
Tasks that need to be performed for each release

In the examples below, it is assumed that the release name will be 1.0.1, and that the current checked-in version name is 1.0.1-SNAPSHOT and stored in the branch named 1.0.x. |
Monday, 12:00 | Make sure the #One time setup steps have been performed | |||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Monday, 12:01 | Create a sub-branch off of the parent branch from which to make the release. Releasing from a branch will allow any cosmetic changes that need to be made for the release to be approved to be done without preventing other more disruptive advances in the trunk from potentially causing problems with the release. A branch can be made by running:
| |||||||||||||||||
Monday, 12:02 | Check out a clean branch from which to build the release:
| |||||||||||||||||
Monday, 12:03 | Update all the POMs to remove "-SNAPSHOT" suffix from the version. If you have perl installed, you can easily do it with a single command:
Update the | |||||||||||||||||
Monday, 12:10 | Verify that LICENSE.txt contains up to date licenses for any dependencies which are included in our distribution. | |||||||||||||||||
Monday, 12:15 | Update BUILDING.txt, CHANGES.txt and RELEASE-NOTES.html
| |||||||||||||||||
Monday, 12:20 | Commit the POM changes
| |||||||||||||||||
Monday, 12:21 | Perform an initial build and install it in the local repository (this step is only required because of an open bug with Maven's javadoc plugin):
| |||||||||||||||||
Monday, 12:23 | Now build the release locally, which will build and test, run the Apache Release Audit Tool to verify license headers, generate the javadoc and docbook PDF and HTML, run through the JPA TCK, build the source and binariy assemblies in target/site/downloads/, and sign the release files.
| |||||||||||||||||
Monday, 13:00 | Verify the signatures:
| |||||||||||||||||
Monday, 13:01 | Upload the release candidate to http://openjpa.apache.org/builds/1.0.1/downloads/:
| |||||||||||||||||
Monday, 15:00 | Start a vote for the release on the dev@openjpa.apache.org mailing list. Votes made by committers and members of the OpenJPA project are considered binding for this vote. For an example of the mail, see this archived 1.0.0 vote | |||||||||||||||||
Tuesday, Wednesday | While waiting for the vote to complete, perform whatever manual review and testing on the release you deem appropriate. | |||||||||||||||||
Thursday, 15:00 | If the vote is successful after 3 days tally the votes in an email to dev@openjpa.apache.org, like this one. | |||||||||||||||||
Thursday, 15:10 | Make the OpenJPA assemblies available to the Apache mirroring system by copying them over on people.apache.org:
| |||||||||||||||||
Thursday, 15:15 | Now that the release is locked down, convert the writeable 1.0.1 branch to a (du jure) read-only tag:
| |||||||||||||||||
Thursday, 15:16 | Check out the parent branch and bump up the release number to be the next snapshot version:
| |||||||||||||||||
Thursday, 15:20 | Update the http://cwiki.apache.org/openjpa/downloads.html page with links to the download mirrors, using the existing entries as templates.
| |||||||||||||||||
Thursday, 15:30 | The documentation on the server-side must manually be extracted on people.apache.org, and the links at http://openjpa.apache.org/documentation.html need to be updated with the new versions and the "latest" documentation symbolic links need to be updated:
| |||||||||||||||||
Thursday, 15:45 | Merge the staged maven2 repository jars to with the official repository to rsync. This is currently a difficult process that requires the maven-staging-plugin, which much be built from source. The process looks something like this (executed in the root of your local OpenJPA checkout):
| |||||||||||||||||
Thursday, 16:00 | Update the JIRA versions page to mark the version as "released", and set the date to the date that the release was approved. You may also need to make a new release entry for the subsequent release. | |||||||||||||||||
Friday, 16:00 | After the mirrors have had time to update (24 hours to be on the safe side), make a news announcement on the OpenJPA wiki.
| |||||||||||||||||
Friday, 16:05 | Make an announcement about the release on the users@openjpa.apache.org list (and, for major releases, on the announce@apache.org list as per the Apache Announcement Mailing Lists page). The announcement might look something like this. | |||||||||||||||||
Friday, 16:10 | Make an announcement for the freshmeat.net OpenJPA project (optional) | |||||||||||||||||
Friday, 17:00 | Have a beer and enjoy your weekend while the world's grateful programmers revel in yet another high-quality release of Apache OpenJPA! |
One time setup

Troubleshooting
Space Character in Build Root Path
Description | If there are spaces in the path to the build root subdirectory, the maven task uses to generate the revision number for the org.apache.openjpa.revision.properties yields incorrect data. For example:
| |||||||
---|---|---|---|---|---|---|---|---|
Solution | Rename the path and remove all spaces. |
Merging local repository to remote repository in Cygwin/Windows
Description | The "maven-stage-plugin" is very sensitive to the parameters being passed to it, i.e. the source and target URL properties. When this plugin is used under Cygwin, make sure the following practices are used:
| ||||||
---|---|---|---|---|---|---|---|
Solution | As recommended in the descriptions.

Cygwin/Windows File Path
Description | For Cygwin/Windows user: file and folder path names using drive identifier (e.g. |

Solution | Consistently use the following naming conventions:
