What is Groovy?

Apache Groovy is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform aimed at improving developer productivity thanks to a concise, familiar and easy to learn syntax. It integrates smoothly with any Java program, and immediately delivers to your application powerful features, including scripting capabilities, Domain-Specific Language authoring, runtime and compile-time meta-programming and functional programming.

How to use this image

Note that if you are mounting a volume and the uid running Docker is not 1000, you should run as user root (-u root).

Starting Groovysh

docker run -it --rm groovy:latest

Running a Groovy script

docker run --rm -v "$PWD":/home/groovy/scripts -w /home/groovy/scripts groovy:latest groovy <script> <script-args>

Reusing the Grapes cache

The local Grapes cache can be reused across containers by creating a volume and mounting it in /home/groovy/.groovy/grapes.

docker volume create --name grapes-cache
docker run --rm -it -v grapes-cache:/home/groovy/.groovy/grapes groovy:latest

Instructions for a new Groovy release

1. Change ENV GROOVY_VERSION in all Dockerfiles to new version number.
2. Update .travis.yml.
3. Update official-images (and docs if appropriate).

Note: Java 9 support is experimental
