Jenesis is a Java-native build tool that vendors its own source into the project and is launched directly by the JDK, eliminating the wrapper binary. It leverages module-info.java for build configuration and content-hashed caching for incremental builds, with benchmarks showing significant speedups for no-op rebuilds. The project also includes jpx, an npx-like module runner for Java.

Target audience: Java backend developers, build engineers, devops
