tools-deps-native

This is an experiment to compile tools.deps with GraalVM native-image.

• resolve mvn deps
• download mvn deps
• resolve git deps
• download git deps

Why

Not needing a JVM for dependency resolution and downloading can speed up things (you don't pay the startup time). I might want to use this for babashka.deps, the namespace in babashka that downloads deps from clojars that can be used in scripts, but it might also have other use cases.

The official Clojure CLI has classpath caching. This tool is about as fast as that without any caching.

Install

A pre-release binaries for macOS and linux are available here.

You can also visit the CircleCI builds for more up to date binaries and download them from the artifacts.

To build from source yourself: see build.

Run

As of now the binary accepts a deps.edn literal map or file and returns the classpath as a string.

Build

To compile this project, point GRAALVM_HOME at your GraalVM distribution and then run script/compile. Using GraalVM 21.0.0 Java 11 CE is recommended.

The build requires clojure to be installed.

After a successful build, there is a tools-deps-native binary which you can pass a deps.edn map.
