IzPack
What it is
IzPack packages, distributes, and deploys Java applications by generating installers. It creates a single installer that runs wherever a Java virtual machine is available, 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. Documented capabilities include command-line packaging, silent installation, auto-update support, and CI/CD integration. Output includes standard JAR installers, web installers, and pack JARs. A Maven plugin is documented, with links to independent Gradle, Scala SBT, and Apache Buildr plugins. The download page identifies IzPack 5.2.7 as the current release. IzPack is free under the Apache Software License 2.0. The project uses mailing lists for updates and feedback and accepts GitHub pull requests. The Windows native launcher from IzPack 4 is not supported in version 5.
