# This is an example for the analysis of the Java event-sourcing library "AxonFramework". 
# It includes the creation of the temporary directory, the working directory, the artifacts download and the analysis itself.

# Note: The first parameter is the version of "AxonFramework" to analyze.
#       All following parameters are forwarded to the "analyze" command.
# Note: This script is meant to be started in the root directory of this repository.
# Note: This script requires "cURL" ( https://curl.se ) to be installed.

# Fail on any error ("-e" = exit on first error, "-o pipefail" exist on errors within piped commands)
set -o errexit -o pipefail

## Get this "scripts" directory if not already set
# Even if $BASH_SOURCE is made for Bourne-like shells it is also supported by others and therefore here the preferred solution. 
# CDPATH reduces the scope of the cd command to potentially prevent unintended directory changes.
# This way non-standard tools like readlink aren't needed.
