Gradle is a build tool designed to take advantage of conventions over (not instead) configuration, while staying flexible enough to be customized to the needs of a particular project. In other words, the build tool bends to the project’s will, not the other way around.
Follows the Maven conventions. Expressive : Prefers a DSL for describing what needs to be done. Extensible : Has a growing an thriving plugin ecosystem. Productive : Fosters fast and reproducible builds. Convenient : It’s CI friendly (gradle wrapper).
Caching of task input and outputs Richer, configurable lifecycle The Gradle deamon The Gradle wrapper Multi-project builds are hassle free Plugin development is more intuitive Better documentation overall

1. Add assembly plugin
2. Create assembly descriptor
1. Dist option for building the directory structure2. Zip option for packing all in a single file
3. Create launch scripts (for all target platforms!)
4. Might require custom profiles
OR configure the appassembler plugin
