Score: 7.0/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 6)

Jrs is a Rust-based build tool for JVM projects that mimics Cargo's ergonomics with a simple TOML manifest, lockfile, and single binary. It handles dependency resolution from Maven Central, supports multiple JVM languages, and offers built-in packaging, testing, and security features without a plugin system. Its focus on reproducibility and supply-chain security makes it a compelling alternative to Maven and Gradle for simpler projects.

Target audience: Java developers, backend devs, devops
