Clojure meets GraalVM

This project contains a set of "hello world" projects to verify which Clojure libraries do actually compile and produce native images under GraalVM.

Here the instructions on how to build your own Clojure projects with GraalVM.

Interesting GraalVM documentation to build native-images:

Understand Class Initialization in Native Image
Native Image Build Configuration
URL Protocols in Native Image for http and https
JCA Security Services in Native Image

How to contribute

If you wish to add a library and contribute with a PR please follow these steps:

Fork the project
use the sample-project as a template. cp -r sample-project my-library
add the library to the project.clj and the native-image parameters used
amend the my-library/src/simple/main.clj to use the library
amend the my-library/README.md with the info you discovered.
Make a PR with your findings and "Thank you" in advance.
