# Save as openapi-generator-cli on your PATH. chmod u+x. Enjoy.

# 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 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.
