|
# 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.
