# 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 JDK17 by default.
# To build with other versions, use "--build-arg JDK_VERSION=[value]"
ARG JDK_VERSION=17

# Step 1 - Download all Dependencies
