jig provides module version resolution, compilation and assembly for the Java Module System. It resolves source modules, local binaries and artifacts published to Maven repositories together, then produces the standard module system arguments accepted by javac, java, javadoc, jlink and other tools.

ja uses jig for module resolution, compilation, assembly and publishing. Prefer ja for module development tasks, using jig directly to bring the same module model to another tool or build.
