IzPack is a widely used tool for packaging applications on the Java platform as cross-platform installers.

IzPack is published under the terms of the Apache License, Version 2.0, meaning that you can adapt it to your needs with very minimal constraints.

Some third-party components (e.g., look and feel libraries) may be released under different terms.

IzPack requires Java SE 1.8 and at minimum Maven 3. Due to the JDK compatibility the maximum Maven version supported is 3.6.3 when compiled using JDK 1.8.

mvn verify install

The build generates a distribution IzPack installer JAR in izpack-dist/target.

The IzPack Maven plugin is inside the izpack-maven-plugin module.

While reporting an issue on our JIRA tracker is useful, investigating and offering a patch is much better!

We suggest that you follow our guidelines for contributing, and especially that you have a fork of https://github.com/izpack/izpack on GitHub. You can then offer contributions using pull requests.

We very much prefer pull requests over attaching patches in a JIRA issues.

During the migration from the Codehaus services, which were shut down, we had do divide different services to separate providers, there hasn't been available a compact offer comparable to the services the Codehaus in such a short time. There are some smaller drawbacks which couldn't be avoided, see below.

If you are wondering where to find some service the project offers visit out web site https://izpack.org/. This domain is still kindly provided and paid by Julien Ponge, the project founder.

The most recent snapshots builds based on the master branch are available on the Soantype Server:

https://oss.sonatype.org/content/repositories/snapshots/org/codehaus/izpack/

Below I provide a list of new services divided by providers:

If you want to participate in development or improving our website, grab a Github account and send pull requests. All you need is the basic idea and the knowledge in using GIT and the Github services.

Don't use the Github issue tracker or Wiki at this time. We use more advanced services for this.

The IzPack source code is hosted at https://github.com/izpack/izpack. See the Developing and contributing section about how to contribute code changes.

Fork the Github repository, create a branch using an according JIRA issue as the branch name for each change and send pull requests from this branch to be able to create a changelog for each release and not get mixed up changes from your master branch for several issues at once.

The IzPack website is hosted at https://github.com/izpack/izpack.github.com. For bigger changes or refactory use a special branch for each change. Send pull requests.

The resulting website izpack.github.com is directly forwarded to izpack.org by an according DNS configuration.

Sonatype provides the service of deploying snapshots and releases to the Maven Central repository.

For us being an open source project with the appropriate license, Sonatype offers a staging repository for our deployed binaries along with using the Nexus Professional repository service for free. See our wiki page Deploying IzPack for more information how this is set up and used.

We have been set up a new JIRA and Confluence cloud instance kindly provided by Atlassian we received an on-demand open source license for. The central address is https://izpack.atlassian.net/.

Although the number of registered users is limited everyone is currently allowed to sign up.

You can sign up to JIRA and Confluence with one and the same user account. It is your choice which one of both services you want use.

IzPack issues will continue to be tracked to JIRA. The central address is https://izpack.atlassian.net/.

By the way, the former Codehaus administrators kindly offered a HTTP redirection from the old Codehaus issues to the new address at Codehaus itself in case there are still old links. This has been activated for all former IZPACK issues and their issues IDs have been kept.

The Github issue tracking has been deactivated to not confuse anyone and because it is just too plain at the moment. There is no real advantage for us at the moment in using Github issues.

The IzPack Wiki has been reimported and left on Confluence. It seems to be the more comfortable choice and better user experience compared to the Github Wiki at the moment.

The central entry point to IzPack Confluence is at https://izpack.atlassian.net/wiki, or check the IzPack documentation directly. The content is considered to be up to date for Izpack 5, feel free to help us directly improving the documentation.

Regarding the mailing lists we ended up in reusing the existing mailing lists at Google Groups. There is a main reason - we kept all the old messages and subscribers from the Codehaus mailing lists mirrored there automatically and can continue to use it slightly.

Please note in advance that these are real mailing lists and you do not need necessarily an Google account at all to join them, see this support notice.

The existing subscribers have been left and don't probably have to re-subscribe. All existing lists have been left, just the mail addresses change.

In particular, there are activated the following lists:

• [email protected]
  Read more about the izpack-announce group.
  Do no longer use the former list [email protected]!
  If you are not a member you can subscribe by sending an e-mail to: [email protected].
• [email protected]
  Read more about the izpack-user group.
  Do no longer use the former list [email protected]!
  If you are not a member you can subscribe by sending an e-mail to: [email protected].
• [email protected]
  Read more about the izpack-dev group.
  Do no longer use the former list [email protected]!
  If you are not a member you can subscribe by sending an e-mail to: [email protected].

If you are not a member of one of the above groups of your interest you may subscribe to them with or without being logged on as Google user on the web interface or by mail. For more help on Google Groups visit the according help center.
