morphir-cli

#!/usr/bin/env sh

# This is a wrapper script, that automatically downloads morphir-cli from maven
# It tries to read the required morphir-cli version in this order:
#  1) --morphir-cli-version parameter
#  2) MORPHIR_CLI_VERSION env variable
#  3) reads from .morphir-cli-version file
#  4) reads from .config/morphir-cli-version file
#  5) tries to fetch newest from Github
#  6) DEFAULT_MORPHIR_CLI_VERSION set in this file
#
# Script Version: 0.4.10
