jbundle

Package JVM applications into self-contained binaries. No JVM installation required.

Transforms JVM applications (Clojure, Java, Kotlin, Scala, Groovy) into self-contained binaries. Previously known as clj-pack, renamed to reflect support for all JVM languages.

Why jbundle?

GraalVM native-image has slow compilations, complex reflection configuration, and library incompatibilities. jbundle bundles a minimal JVM runtime with your uberjar into a single executable—full JVM compatibility, no external dependencies.
