# Use case:
#
# The purpose of this script is to compact the steps required to regenerate TypeSpec into a single script.
#
# If 'com.azure.autorest.customization' tests fails, re-install 'customization-base'.
#
# Before running this script the 'tsp' profile must be built, 'mvn install -P local,tsp'.
#
# This script can only be ran from the root of the repository.

# Invokes the given expression and only writes the output of the expression if it failed.
