We need you!


The IzPack documentation needs work, and you are invited to edit it!

The server IDs are given by the Codehaus parent POM, use your Codehaus account as username and password. For encoding information on how to encrypt your personal password see the Maven documentation.


  1. Download the StartSSL CA and StartSSL Intermediate CA to your local filesystem.
  2. Install the downloaded certificate into the JDK


For more information, see Installing a new CA into the JDK.


If the certificate files attached here should be outdated, export the current certificate from your browser after navigating to https://nexus.codehaus.org/.

Deploying IzPack Snapshots


For a comprehensive manual how to manage Codehaus deployments see Performing a Release. 

For your own security, using --batch-mode is not really recommended since you have to enter your GPG passphrase in clear text on the command line, which could be saved for example in .bash_history. Rather wait and enter this passphrase as soon as Maven requests it on the command line input.

As an example, we will consider the release of version 5.20.0-rc2.

Do a dry run

No Format
mvn -Dtag=izpack-5.0.0-rc2 release:prepare [--batch-mode] -DdryRun=true \
                    -DdevelopmentVersion-DreleaseVersion=5.20.10-SNAPSHOT \
                    -DreleaseVersionrc2 -DdevelopmentVersion=5.20.0 \
                    -DpreparationGoals='clean verify install' \


-rc3-SNAPSHOT -Dusername=<your_codehaus_login>


Build locally and prepare the staging repository at Codehaus Nexus:

No Format
mvn release:clean
mvn release:prepare [--batch-mode] \
                    -DdevelopmentVersion=5.2.1-SNAPSHOT \
                    -DreleaseVersion=5.2.0 \
                    -DpreparationGoals='clean verify install' \
                    -Dusername=your_codehaus_login-Dtag=izpack-5.0.0-rc2 release:prepare -DreleaseVersion=5.0.0-rc2 -DdevelopmentVersion=5.0.0-rc3-SNAPSHOT -Dusername=<your_codehaus_login>

mvn release:perform -Dusername=your_codehaus_login


Code Block
git push origin master
git push --tags


 origin master

and to Codehaus (provided a remote codehaus initialized to ssh://nexusgit@git.codehaus.org/izpack.git):

Code Block
#git remote add codehaus ssh://git@git.codehaus.org/izpack.git
git push codehaus master
git push --tags codehaus master


Close, promote and release from the staging repository at Codehaus Nexus:

Log in at Codehaus Nexus Staging Repositories, check the staging repository and if everything is fine, close Close and release Release it (in this order).


  • You won't be able to perform release:prepare without having the HTTP credentials set in settings.xml, to be able to upload files to the staging storage at Codehaus Nexus
  • You won't be able to close a Nexus staging repository without having your GPG key exported to a key server.
  • Things work better if your local account name matches the one at Codehaus, and you don't have to specify the username parameter. Otherwise, things may break, especially the Git pushes.

Recovering from Failed Releases

There are several states you may get in after the release process described above fails:

Recover the staging repository:

Log in at  Codehaus Nexus Staging Repositories, select the the staging repository entry which failed and drop it.

Reset the local git repository to the state before releasing:

First remove the additional files generated by the release plugin:

Code Block
mvn release:clean

Using git log get  the latest commit before the auto-generated commit of the release plugin follow, for example:

Code Block
commit 49a769a0eefa7476d5ccc3849692ffe7b6e5ed2e
Merge: d682c30 3218c81
Author: René Krell <renda.krell@gmail.com>
Date: Tue Oct 15 09:45:05 2013 -0700
Merge pull request #143 from rkrell/IZPACK-993

[IZPACK-993] Dynamic variables - add configuration attribute to control whether to escape backslashes when reading from option and INI files

Now you can reset the local repository to the original state (or using FETCH_HEAD if the remote repository is still blocked and unchanged).

Code Block
git reset --hard  49a769a0eefa7476d5ccc3849692ffe7b6e5ed2e

Check whether the release plugin has already tagged the target version using git tag. If yes, delete the tag to avoid release:perform from failing:

Code Block
git tag --delete izpack-5.0.0-rc1

Now you can repeat the release process from the beginning.


Post-processing and Announcing Releases

  1. Use WebDAV at https://dav.codehaus.org/dist/izpack/ to push releases from the Maven repository
    Example 5.0.0-rc1:
    Copy izpack/izpack-dist/target/izpack-dist-5.0.0-rc1.jar  to  webdavs://<xircles_username>@dav.codehaus.org:443/dist/izpack/releases/5.0.0-rc1/izpack-dist-5.0.0-rc1-installer.jar
