jrs builds, tests, runs, and packages Java, Kotlin, Scala, and Groovy projects from a single jrs.toml manifest.

Landing page captured for the 2026-09-13 issue.

Field notes

jrs places project metadata, language settings, and dependency declarations in jrs.toml, then records resolved versions and checksums in a committed jrs.lock. The documented workflow covers Maven Central resolution, verified caching, offline builds, multiple JVM languages, JUnit and JaCoCo reporting, and several packaging formats. It requires JDK 17 or newer and deliberately targets single-module projects rather than reproducing the full Maven or Gradle feature set.
