#
# This script will query github on every invocation to pull the latest released version
# of openapi-generator.
#
# If you want repeatable executions, you can explicitly set a version via
# OPENAPI_GENERATOR_VERSION
# e.g. (in Bash)
# export OPENAPI_GENERATOR_VERSION=3.1.0
# openapi-generator-cli.sh
# or
# OPENAPI_GENERATOR_VERSION=3.1.0 openapi-generator-cli.sh
#
# This is also helpful, for example, if you want want to evaluate a SNAPSHOT version.
#
# NOTE: Jars are downloaded on demand from maven into the same directory as this script
# for every 'latest' version pulled from github. Consider putting this under its own directory.
