IzPack
IzPack generates installers for packaging and deploying Java applications.
What IzPack is
IzPack generates installers for packaging and deploying Java applications. It creates a single installer that runs on operating systems with a Java virtual machine, with Windows, Linux, Solaris, and Mac OS X listed as destinations. Users can select installer components and appearance, then extend installers with additional features. Optional native integration can create desktop shortcuts, modify a system registry, or switch to an administrator account during installation. The project documents command-line packaging, silent installation, auto-update support, and CI/CD integration. Its download page identifies version 5.2.7 as the current release. A Maven plugin is documented, with links to independent plugins for Gradle, Scala SBT, and Apache Buildr. IzPack is published under the Apache Software License 2.0. The project invites contributions through GitHub pull requests and directs users to mailing lists for updates and feedback. The Windows native launcher available with IzPack 4 is not supported in version 5 because it lacks a maintainer. No paid plans are listed.
