Requirements

• gnu make

Usage

A simple scala project is provided for testing, it has been created from the basic scala template:

sbt new scala/scala-seed.g8

but you can replace it by any other scala project you are interested in.

The following instructions expect a sbt project in the root level of this directory.

make help

// test with openjdk 8
make build-with-openjdk8

For debugging purposes you may want to ssh into the container:

env IMAGE=adoptopenjdk/openjdk11-openj9 ./docker-openjdk-x sh
# java -version

As they are minimal images, a setup task is provided, azul image I'm looking at you, to download an sbt launch jar.

make setup
make build-with-azul

Finally, if you encounter permission problems, just run make clean.
