Capsule

Capsule is a packaging and deployment tool for JVM applications. A capsule is a single executable JAR that contains everything your application needs to run either in the form of embedded files or as declarative metadata. It can contain your JAR artifacts, your dependencies and resources, native libraries, the require JRE version, the JVM flags required to run the application well, Java or native agents and more. In short, a capsule is a self-contained JAR that knows everything there is to know about how to run your application the way it's meant to run. One way of thinking about a capsule is as a fat JAR on steroids (that also allows native libraries and never interferes with your dependencies) and a declarative startup script rolled into one; another, is to see it is as the deploy-time counterpart to your build tool. Just as a build tool manages your build, Capsule manages the launching of your application.
