Making an OpenJPA Release

These instructions guide through the steps of making an official OpenJPA release.


  1. You should have read the Apache Guide To Release Management During Incubation
  2. You must have shell access to
  3. You must have the following utilities installed on your local machine and available in your path:

Tasks that need to be performed for each release

In the examples below, it is assumed that the current committed version of OpenJPA is 0.9.6-incubating-SNAPSHOT, and the version of the official release will be 0.9.6-incubating
1 Make sure the One time setup steps have been performed
2 Update the POMs to remove "-SNAPSHOT" from the version. If you have perl installed, you can easily do it with a single command:
perl -pi -e 's;<version>0.9.6-incubating-SNAPSHOT</version>;<version>0.9.6-incubating</version>;g' pom.xml */pom.xml
3 Commit the POM changes
svn commit -m "Updated to version 0.9.6-incubating"
4 Perform the build with documentation and install it in the local repository (this step is required because there is a bug in Maven's javadoc generation aggregated between multiple modules):
mvn clean install -Pdocbook-profile,sign-release
This operation will also sign the release files with the gpg utility using the <username> key. If your code signing key is under a different address, specify it by appending the following argument to the command above:
5 Verify the signatures:
gpg --multifile --verify openjpa-project/target/assembly/*.asc
6 Now actually build the javadocs and perform the deploy upload:
mvn verify deploy -Pjavadoc-profile,sign-release
7 Tag the view with the release number:
svn copy -m "OpenJPA Release 0.9.6-incubating"
8 Update the pom.xml files to the subsequent version with the -SNAPSHOT suffix:
perl -pi -e "s;<version>0.9.6-incubating</version>;<version>0.9.7-incubating-SNAPSHOT</version>;g" pom.xml */pom.xml
9 Commit the POM changes
svn commit -m "Updated to version 0.9.7-incubating-SNAPSHOT"

One time setup

These setup steps only need to be performed on a particular machine once.

Developers using Linux workstations can skip over the references to PuTTY and Cygwin

Create and install a SSH key

1 Install PuTTY
2 Use PuttyGen to create a SSH key (see Putty help for details)
3 Use PuTTY to ssh to
4 Create a ~/.ssh folder
5 pscp your SSH public key to ~/authorized_keys
6 ssh to p.a.o
7 Create a ~\.ssh folder and move authorized_keys there
8 Configure putty to use your private key and save the session

Create a PGP key

1 Install cgywin, including utils/gpg
2 Generate a key with $ gpg --gen-key
3 Backup your cygwin home directory to another media
4 Add your key to

Update Maven settings for our servers

1 Create a settings.xml under .m2 (in your Document and Settings folder in Windows)
<settings xmlns=""

Expose a copy of known hosts to Maven

1 From cygwin, ssh to, save the public key if prompted, and exit
  cygwin will save the known hosts to your ~/.ssh folder, but the script cannot access it there (from Windows)
2 From cygwin (not Windows) create another .ssh folder at
3 Copy the known_hosts file to the new .ssh folder
