# This script is used to test JetBrains prebuild warmup indexing (search warmup-indexing.sh in codebase)
# It will get the last indexing json file (scan reason `On project open`)
# and check if the scheduled indexing count is greater than a specified threshold
#
# `exit 0` means JetBrains IDEs no need to indexing again
# Example: ./warmup-indexing.sh /workspace 1
