# This image will be published as dspace/dspace-dependencies
# The purpose of this image is to make the build for dspace/dspace run faster

# This Dockerfile uses JDK11 by default, but has also been tested with JDK17.
# To build with JDK17, use "--build-arg JDK_VERSION=17"

# This ensures when dspace:dspace is built, it will use the Maven local cache (~/.m2) for dependencies
