Capsule is a packaging and deployment tool for JVM applications that builds a single executable JAR containing the app's artifacts, dependencies, native libraries, required JRE version, and JVM flags as embedded files or declarative metadata. Extensible 'caplets' let capsules handle advanced launching behavior, acting as the deploy-time counterpart to a build tool.

Use cases

  • package a JVM app as a single executable jar
  • ship a java application with all dependencies bundled
  • deploy a jar that specifies its required JRE version and JVM flags
  • bundle native libraries with a java application
  • replace fat jars and startup scripts with one self-contained artifact

When to avoid

  • you need a modern, actively maintained packaging tool (development largely stopped after 2016)
  • you prefer container images or native-image tooling like GraalVM for deployment
  • you need OS-specific installers or application bundles
